A communication terminal includes a memory and circuitry. The memory stores, for each image type information indicating a type of image data, sizes of a plurality of display areas, each display area being a divided area divided from an entire area displayable by a display, in association with required resolutions of image data to be displayed in the corresponding display areas. The circuitry receives, from a communication management system, specific image type information indicating a type of specific image data transmitted from other communication terminal. The circuitry transmits, to the communication management system, specific required resolution, which is a resolution stored in the memory for the specific image type information in association with the size of one of the display areas in which the specific image data is to be displayed.

An image capturing device may capture image data for processing to form an image. The image capturing device may perform a hashing procedure on the image data, wherein performing the hashing procedure generates a hash value of the image data. The image capturing device may provide, to an image authentication device, the hash value of the image data, wherein the hash value of the image data is to be used by the image authentication device to validate the image based on a request to authenticate the image received from a receiving device. The image capturing device may process the image data to form the image for display to a user. The image capturing device may provide, after providing the hash value of the image data to the image authentication device, the image for display to the user.

An imaging control method is provided. The method may include obtaining a current image generated based on an exposure parameter, wherein the current image includes a plurality of pixels; determining a plurality of target pixels or target pixel groups from at least portion of the plurality of pixels; determining a statistic representation based on target pixels or target pixel groups; determining a characteristic feature based on the statistic representation; and, updating the exposure parameter, based on the characteristic feature, to generate an updated image.

Embodiments of the present disclosure include apparatuses and methods for sensor blocking. In a number of embodiments, a method can include operating a sensor block of an apparatus in a first mode to allow a sensor to receive inputs, and operating the sensor block in a second mode to inhibit the sensor from receiving the inputs. A sensor block can be used to prevent a sensor, such as an image sensor, from receiving an input, such as a light source input, to capture image data. A sensor block can be used to prevent a sensor from capturing image data even when an application causing to the sensor to operate, such as when applications have access to the sensor, but the user of a device is unaware that an application is using the sensor. The sensor block can be used to prevent the sensor from capturing useful images and the sensor can only capture a black image of the sensor block and not the surroundings of the device.

In a communication system, an image forming apparatus sends an address of a receiving section to an external device. The external device receives a selection of image data through plural thumbnails displayed on a display section, and wirelessly sends the selected image data to the image forming apparatus with the address. The image forming apparatus receives the selected image data sent with the address by the external device, and prints an image based on the selected image data. The image forming apparatus accepts a selection indicating whether a communication between the external device and the image forming apparatus is performed by a first communication system method or a second communication system method. The image forming apparatus performs sending and/or receiving the image data with the address by the first communication system method when the first communication system method is selected, and performs sending and/or receiving the image data with the address by the second communication system method when the second communication system method is selected.

A method, apparatus and computer program product are provided to define the location of a center point associated with each frame within a stream of image data. Metadata associated with the orientation, such as the pitch and yaw, of a camera is synchronized on a frame-by-frame basis with a related stream of image data. In connection with receiving the image data and the orientation data, the method defines a center point associated with a video frame images and transmits a control signal causing the reorientation of at least a subset of video image frames. In some example implementations, arising in the context of 360° video streams, the rotation of the head of a viewer of virtual reality content or other 360° video streams may be taken into account when defining the location of a center point.

A contextual local image recognition module of a device retrieves a primary content dataset from a server and then generates and updates a contextual content dataset based on an image captured with the device. The device stores the primary content dataset and the contextual content dataset. The primary content dataset comprises a first set of images and corresponding virtual object models. The contextual content dataset comprises a second set of images and corresponding virtual object models retrieved from the server.

An image capturing control apparatus includes a detection unit configured to detect a specific object area in an image captured by an image capturing apparatus, an acquisition unit configured to acquire a first input/output characteristic of the image capturing apparatus, a conversion unit configured to convert the image by acquiring a second input/output characteristic that is an inverse input/output characteristic to the first input/output characteristic, and by applying the second input/output characteristic to the image, and a control unit configured to control exposure of the image capturing apparatus based on a luminance value of the specific object area in the converted image.

A visible light sensor may be configured to sense environmental characteristics of a space using an image of the space. The visible light sensor may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the visible light sensor may be configured to decrease or eliminate glare within a space. In the daylighting sensor mode and the color sensor mode, the visible light sensor may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the visible light sensor may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.

A digital camera with a printer is a digital camera with a printer and includes a communication unit that communicates with a digital camera with a printer that is another apparatus, and an image composition unit that generates a composite image in which a first image captured by the digital camera with a printer that is an owned apparatus and a second image captured by the other apparatus are composited, in which the communication unit transmits the composite image to the other apparatus. A user of the other apparatus can also obtain the composite image. Accordingly, the composite image can be enjoyed by capturing images using a plurality of cameras.
