[0046] FIG. 1 is a block diagram showing an apparatus for controlling vehicle interior lighting according to embodiments of the present disclosure.

[0047] Referring to FIG. 1, an apparatus for controlling vehicle interior lighting 100 according to embodiments of the present disclosure may include a first communication module 110, a second communication module 120, a lighting module 130, a memory 140, and a processor 150. Each of the components included in the apparatus for controlling vehicle interior lighting 100 according to embodiments of the present disclosure may be connected via (or through) a common bus, or may be connected through an individual interface or an individual bus centered on the processor 150. The apparatus for controlling vehicle interior lighting 100 according to embodiments of the present disclosure may further include various other components in addition to the components illustrated in FIG. 1, or may not include some of the components illustrated in FIG. 1.

[0048] The first communication module 110 may perform communication with a display device disposed (or installed) in a vehicle. The first communication module 110 may perform communication with the display device by using various types of communication methods. The display device is a device that includes a display for outputting an image, and may include a navigation system. The first communication module 110 may perform communication with the display device, for example, by using a wired communication. However, the communication method of the first communication module 110 is not limited to the embodiments described above, and the first communication module 110 may perform communication with the display device by using a variety of known communication methods.

[0049] The second communication module 120 may perform communication with a mobile device located within the vehicle. The second communication module 120 may perform communication with the mobile device by using various types of communication methods. The mobile device is a device that includes a display for outputting an image, and may include a variety of wireless electronic devices, such as a smartphone, tablet, and laptop. The second communication module 120 may perform communication with the mobile device by using, for example, Wi-Fi Direct technology. However, the communication method of the second communication module 120 is not limited to the embodiments described above, and the second communication module 120 may perform communication with the mobile device by using a variety of known wireless communication methods.

[0050] The lighting module 130 may illuminate a vehicle interior with light. The lighting module 130 may include a plurality of light sources 131. Each of the light sources 131 may be disposed or installed at different locations in the vehicle. The light sources 131 may illuminate the interior of the vehicle with various colors of light. The colors of the light output by the plurality of light sources 131 may be different from each other. For example, the lighting module 130 may output ambient light.

[0051] The memory 140 may store at least one instruction executed by the processor 150. The memory 140 may be implemented as a volatile storage medium and/or a non-volatile storage medium, for example, as read-only memory (ROM) and/or random access memory (RAM). The memory 140 may store various information required during the operation of the processor 150. In addition, the memory 140 may store various information generated during the operation of the processor 150.

[0052] The processor 150 may be operatively connected to the first communication module 110, the second communication module 120, the lighting module 130, and the memory 140. The processor 150 may be implemented in a central processing unit (CPU) or a system on chip (SoC), may run an operating system or an application to control a plurality of hardware or software components connected to the processor 150, and may perform various data processing and computations. The processor 150 may be configured to execute at least one instruction stored in the memory 140 and to store the resulting data in the memory 140.

[0053] The processor 150 may receive first image information, which is information on an image being output on the display device, via (or through) the first communication module 110, generate first color information based on the first image information, and control the lighting module 130 based on the first color information. The present embodiment may change the output color of the light sources in the vehicle in response to the image being output on the display device, thereby enhancing a user's immersion in the image being output on the display device.

[0054] The processor 150 may receive second image information, which is information on an image being output on the mobile device, via (or through) the second communication module 120, generate second color information based on the second image information, and control the lighting module 130 based on the second color information. The present embodiment may change the output color of the light sources in the vehicle in response to the image being output on the mobile device, thereby enhancing a user's immersion in the image being output on the mobile device.

[0055] FIG. 2 is a first flowchart showing a method for controlling vehicle interior lighting according to embodiments of the present disclosure. FIGS. 3A and 3B are example views illustrating a method of dividing a frame into a plurality of areas. FIGS. 4 and 5 are example views showing the results of controlling a lighting module.

[0056] Referring to FIG. 2, a method for controlling the lighting module 130 depending on the image being output on the display device, will be described below, with a focus on an operation of the processor 150. Some of the steps described below may be performed in a different order than the order described below, or may be omitted.

[0057] First, the processor 150 may receive first image information, which is information on an image being output on the display device, via or through the first communication module 110 (S201). The first image information may include color information, for each area, on the image being output on the display device. In various embodiments, the processor 150 may receive information on only some areas (e.g., edge areas) of the image being output on the display device.

[0058] Next, the processor 150 may sample the first image information to extract a first frame (S203). The first frame may refer to an image being output on the display device at a specific point in time. In step S203, the processor 150 may perform sampling at a predetermined set interval. The set interval may be changed depending on the interior illuminance of the vehicle. To this end, the apparatus for controlling vehicle interior lighting 100 may further include an illuminance sensor configured to detect the interior illuminance of the vehicle. Relationship information on the interval depending on the interior illuminance may be preset and stored in the memory 140, and the processor 150 may detect the interval corresponding to a current interior illuminance from the relationship information stored in the memory 140, and set the detected interval as a set interval. The interval at which the light sources 131 change colors may be changed depending on the set interval.

[0059] Next, the processor 150 may divide the first frame into a plurality of areas (S205). As illustrated in FIG. 3A, the processor 150 may divide the first frame into three areas. In various embodiments, as illustrated in FIG. 3B, the processor 150 may divide the first frame into nine areas. However, the manner in which the first frame is divided into a plurality of areas is not limited to the embodiments described above, and the first frame may be divided in a variety of manners. The size and number of the plurality of areas may be set by considering the number of the light sources 131, the location of the light sources 131, and the like.

[0060] Next, the processor 150 may determine a representative color for each of the plurality of areas (S207). In various embodiments, the processor 150 may determine representative colors for only some areas (e.g., edge areas) out of the plurality of areas. For example, if the first frame is divided as shown in FIG. 3A, the processor 150 may determine representative colors for the left and right areas and not determine a representative color for the central area.

[0061] Next, the processor 150 may generate the first color information by including the representative color for each of the plurality of areas (S209). In step S209, the processor 150 may generate the first color information by integrating information on the representative colors determined in step S207.

[0062] Next, the processor 150 may control the lighting module 130 based on the first color information (S211). In step S211, the processor 150 may identify a representative color of the area corresponding to each of the plurality of light sources 131 by using the first color information, and may control the lighting module 130 such that each of the plurality of light sources 131 outputs light having the representative color of the area corresponding to each of the plurality of light sources 131. For example, as illustrated in FIG. 4, assuming that the representative color of a first area 10a is a first color and the representative color of a second area 10c is a second color, the processor 150 may change the color of a first light source 131a and a third light source 131c, which are the light sources corresponding to the first area 10a, into the first color, and change the color of a second light source 131b and a fourth light source 131d, which are the light sources corresponding to the second area 10c, into the second color.

[0063] In this case, the processor 150 may determine a location of a user, identify at least one light source 131, out of the plurality of light sources 131, corresponding to the location of the user, and control only the at least one identified light source 131. The processor 150 may receive information on the location of the user from various sensors and systems provided in the vehicle. For example, the processor 150 may receive information on the location of the user from an airbag system. To this end, the apparatus for controlling vehicle interior lighting 100 may include a separate communication module (third communication module) for communicating with sensors and/or systems in the vehicle.

[0064] In the present embodiment, the light source corresponding to the location of the user may refer to a light source of which the output light (or color of light) is detected in the user's field of view. For example, as illustrated in FIG. 5, assuming that the representative color of the first area 10a is a first color, the representative color of the second area 10c is a second color, and the user is located in a driver's seat A, the processor 150 may only change the colors of the first light source 131a and the second light source 131b, which are light sources that are detected in the driver's seat A, and not change the colors of the third light source 131c and the fourth light source 131d, which are light sources that are not detected in the driver's seat A, thereby reducing unnecessary power consumption.

[0065] FIG. 6 is a flowchart showing a method of determining a representative color for a random area. FIG. 7 is an example view showing the result of selecting points in an area.

[0066] Referring to FIG. 6, a method for determining a representative color for a random area will be described below, with a focus on an operation of the processor 150. Some of the steps described below may be performed in a different order than the order described below, or may be omitted. The processor 150 may perform the process in FIG. 6 for each of the plurality of areas.

[0067] First, the processor 150 may randomly select a number (n) of points in an area for which a representative color is to be determined (hereinafter the target area) (S601). For example, assuming that the target area is the right area and n is 10, the processor 150 may select points as illustrated in FIG. 7. n may be pre-set to a suitable value.

[0068] Next, the processor 150 may detect a color value at each of the number (n) of the randomly selected points (S603). In the present embodiment, a color value may refer to an RGB value. The processor 150 may calculate a difference between a color value detected from a previous frame and a color value detected from a current frame, and may change a set interval (sampling interval) based on the calculated difference. The processor 150 may decrease the set interval as the difference between the color value detected from the previous frame and the color value detected from the current frame becomes greater.

[0069] Next, the processor 150 may calculate a median value for the color values detected in step S603 (S605), and determine a color corresponding to the calculated median value as a representative color for the target area (S607). In various embodiments, the processor 150 may utilize an average value, a maximum value, or a minimum value instead of a median value. The processor 150 may receive user input regarding which value to use among the median, average, maximum, and minimum values, and may determine which value to use based on the received user input.

[0070] FIG. 8 is a flowchart showing a method of controlling a light source based on first color information.

[0071] Referring to FIG. 8, a method for controlling the light sources 131 based on the first color information will be described below, with a focus on an operation of the processor 150. Some of the steps described below may be performed in a different order than the order described below, or may be omitted. The processor 150 may perform the process in FIG. 8 for each of the plurality of light sources 131 included in the lighting module 130.

[0072] First, the processor 150 may determine a location of the display device (S801). Information on the location of the display device may be pre-stored in the memory 140, and the processor 150 may determine the location of the display device from the memory 140.

[0073] Next, based on the location of the display device and the location of a light source to be controlled (hereinafter the target light source), the processor 150 may identify an area corresponding to the target light source among the plurality of areas constituting the first frame (S803). Information on the location of each of the light sources 131 may be pre-stored in the memory 140, and the processor 150 may determine the location of the target light source from the memory 140. In step S803, the processor 150 may identify an area closest to the target light source as the area corresponding to the target light source. Mapping information in which the relationship information on the corresponding area depending on the location of the light sources 131 is set for each location of the display device may be pre-stored in the memory 140, and the processor 150 may identify the area corresponding to the target light source by using the mapping information.

[0074] However, the method of identifying the area corresponding to the target light source is not limited to the embodiments described above, and the processor 150 may identify the area corresponding to the target light source by using various methods, by considering the locations of both the display device and the target light source. There may be one or more light sources 131 corresponding to the area.

[0075] Next, the processor 150 may detect a representative color for the area identified in step S803 from the first color information (S805). Information on representative colors for each area may have been recorded in the first color information, and the processor 150 may detect a representative color for the area corresponding to the target light source from the first color information.

[0076] Next, the processor 150 may control the target light source to output light having the representative color detected in step S805 (S807).

[0077] FIG. 9 is a second flowchart showing a method for controlling vehicle interior lighting according to embodiments of the present disclosure.

[0078] Referring to FIG. 9, a method for controlling the lighting module 130 depending on the image being output on the mobile device, will be described below, with a focus on an operation of the processor 150. Some of the steps described below may be performed in a different order than the order described below, or may be omitted.

[0079] First, the processor 150 may receive second image information, which is information on an image being output on the mobile device, via or through the second communication module 120 (S901). The second image information may include color information for each area on the image being output on the mobile device. In various embodiments, the processor 150 may receive information on only some areas (e.g., edge areas) of the image being output on the mobile device.

[0080] Next, the processor 150 may sample the second image information to extract a second frame (S903). The second frame may refer to an image being output on the mobile device at a specific point in time. In step S903, the processor 150 may perform sampling at a predetermined set interval. The set interval may be changed depending on the interior illuminance of the vehicle.

[0081] Next, the processor 150 may divide the second frame into a plurality of areas (S905). The size and number of the plurality of areas may be set by considering the number of the light sources 131, the location of the light sources 131, and the like.

[0082] Next, the processor 150 may determine a representative color for each of the plurality of areas (S907). In various embodiments, the processor 150 may determine representative colors for only some areas (e.g., edge areas) out of the plurality of areas.

[0083] Next, the processor 150 may generate the second color information by including the representative color for each of the plurality of areas (S909). In step S909, the processor 150 may generate the second color information by integrating information on the representative colors determined in step S907.

[0084] Next, the processor 150 may control the lighting module 130 based on the second color information (S911). In step S911, the processor 150 may identify a representative color of the area corresponding to each of the plurality of light sources 131 by using the second color information, and may control the lighting module 130 such that each of the plurality of light sources 131 outputs light having the representative color of the area corresponding to each of the plurality of light sources 131.

[0085] In this case, the processor 150 may determine a location of a user, identify at least one light source 131, out of the plurality of light sources 131, corresponding to the location of the user, and control only the at least one identified light source 131. In the present embodiment, the light source corresponding to the location of the user may refer to a light source of which the output light is detected in the user's field of view.

[0086] FIG. 10 is a flowchart showing a method of controlling a light source based on second color information.

[0087] Referring to FIG. 10, a method for controlling the light sources 131 based on the second color information will be described below, with a focus on an operation of the processor 150. Some of the steps described below may be performed in a different order than the order described below, or may be omitted. The processor 150 may perform the process in FIG. 10 for each of the plurality of light sources 131 included in the lighting module 130.

[0088] Next, the processor 150 may determine a location of the mobile device (S1001). The apparatus for controlling vehicle interior lighting 100 may include a capture module (e.g., a camera), and the processor 150 may determine a location of the mobile device based on the image captured by the capture module.

[0089] Next, based on the location of the mobile device and the location of a light source to be controlled (hereinafter the target light source), the processor 150 may identify an area corresponding to the target light source among the plurality of areas constituting the second frame (S1003). In step S1003, the processor 150 may identify an area closest to the target light source as the area corresponding to the target light source. Mapping information in which the relationship information on the corresponding area depending on the location of the light sources 131 is set for each location of the mobile device may be pre-stored in the memory 140, and the processor 150 may identify the area corresponding to the target light source by using the mapping information.

[0090] Next, the processor 150 may detect a representative color for the area identified in step S1003 from the second color information (S1005). Information on representative colors for each area may have been recorded in the second color information, and the processor 150 may detect a representative color for the area corresponding to the target light source from the second color information.

[0091] Next, the processor 150 may control the target light source to output light having the representative color detected in step S1005 (S1007).

[0092] As described above, the apparatus and the method for controlling vehicle interior lighting according to embodiments of the present disclosure may control vehicle interior lighting to correspond to an image output on the display device or mobile device, thereby enhancing the user's immersion in the image output on the display device or mobile device.
