A multi-mode display includes a mode selector to select one of a plurality of modes, each of the modes having a different light configuration, wherein one mode comprises a reduced color space mode, and one or more light sources controlled by the mode selector, the one or more light sources used to display content to a user with the multi-mode display.

This application provides a bullet-screen comment display method. The bullet-screen comment display method includes: obtaining a to-be-displayed target bullet-screen comment; in a case in which a display type of the target bullet-screen comment is a multi-direction bullet-screen comment display type, obtaining a pre-configured motion parameter corresponding to the multi-direction bullet-screen comment display type, where the multi-direction bullet-screen comment display type is a bullet-screen comment display type in which mobile display is performed from a preset start position to multiple preset movement directions; and dynamically displaying the target bullet-screen comment along a target movement direction from the preset start position based on the motion parameter.

Disclosed are a system and method for providing an electronic book based on a reading type, which can provide one electronic book in various forms depending on the reading types of users. A reader terminal of the system outputs an electronic book, which has different texts and image ratios depending on the reading type of a user, on a screen, detects a sight area at which the user stares, by capturing an image of eye movement of the user who reads the electronic book, and sets and updates the reading type of the user based on the sight area.

A display device includes a display panel including a correction area in which a correction image including a logo image and a logo background image is displayed, and a panel driving block. The panel driving block includes a luminance correction block which corrects a luminance of the correction image, and the luminance correction block includes a first correction block which divides the correction area into a plurality of sub-areas, based on a distance from the logo image and generates an area correction signal for correcting the luminance of the correction image, a second correction block which generates a luminance correction signal for correcting the luminance of the correction image displayed in each of the sub-areas, based on a grayscale of the image signal and the area correction signal, and a third correction block which corrects the luminance of the correction image.

A method for tying a virtual speaker to a physical space. A first user with a first wearable extended reality appliance enters an area associated with a virtual speaker. First sounds are transmitted from the virtual speaker to the first wearable extended reality appliance. The first user hears the first sounds at first settings of the virtual speaker. The first user changes the settings of the virtual speaker to second settings. Second sounds are transmitted from the virtual speaker to the first wearable extended reality appliance, such that the first user hears the second sounds at the second settings. After the first user leaves the area, a second user with a second wearable extended reality appliance enters the area. Third sounds are transmitted from the virtual speaker to the second wearable extended reality appliance, such that the second user hears the third sounds at the second settings.

An electronic device includes a display panel, a data driving circuit, a scan driving circuit, and a signal control circuit that receives input data. The signal control circuit includes a histogram check unit that divides data of one frame among the input data into a plurality of regions based on a gray scale and calculates a distribution of the data based on the plurality of regions, a gray check unit that calculates the number of major grayscales having data of a specific number or more among the input data, an optical waveform analysis unit that generates a signal calculated based on an optical waveform of the plurality of pixels, and a frequency selection unit that selects a driving frequency of the display panel based on the distribution of the data, the number of the major grayscales, and the signal.

An image processing apparatus comprises a receiver (201) for receiving an image signal which comprises at least an encoded image and a target display reference. The target display reference is indicative of a dynamic range of a target display for which the encoded image is encoded. A dynamic range processor (203) generates an output image by applying a dynamic range transform to the encoded image in response to the target display reference. An output (205) then outputs an output image signal comprising the output image, e.g. to a suitable display. The dynamic range transform may furthermore be performed in response to a display dynamic range indication received from a display. The invention may be used to generate an improved High Dynamic Range (HDR) image from e.g. a Low Dynamic Range (LDR) image, or vice versa.

A method and apparatus therefor comprises: receiving an image data and a power metadata, wherein the power metadata includes information relating to a power consumption or an expected power consumption; determining, based on the power metadata, an amount and a duration of a drive modification that may be performed by a target display in response to the power consumption or the expected power consumption; and performing a power management of the target display based on the power metadata to modify a driving of at least one light-emitting element associated with the target display relative to a manufacturer-determined threshold, based on a result of the determining, wherein the power metadata includes at least one of a temporal luminance energy metadata, a spatial luminance energy metadata, a spatial temporal fluctuation metadata, or combinations thereof.

An information processing apparatus includes a processor configured to perform control for displaying a first screen for receiving a change of setting of processing and an execution instruction of the processing, cause the screen to transition while maintaining first setting that is setting changed on the first screen, and perform notification that the first setting is changed upon receiving the execution instruction of the processing is received on the first screen in a case where a transition from the first screen to a second screen for receiving a change of second setting related to the processing or from the first screen to the second screen for receiving processing different from the processing received on the first screen is made during a period from the change of the first setting to reception of the execution instruction of the processing received on the first screen.
