IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, PROGRAM, AND IMAGE PROJECTION METHOD
An image processing apparatus generates, from a mixed image of projection images projected from a plurality of projection devices, separated images for respective pieces of color information, on the basis of a color model. For the color model, the pieces of color information of the projection images changed according to spectral characteristics of the projection devices and an image pickup device for acquiring the captured image and an attenuation coefficient are used as parameters, and a color separation processing section generates the separated images for the respective pieces of color information on the basis of the color model, by using parameters that minimize the difference between the color information of the captured image and color information estimated by the color model. The image processing apparatus becomes able to accurately separate projection images from the captured image of the mixed image including a plurality of projection images.

Method for rendering color images
A system for rendering color images on an electro-optic display when the electro-optic display has a color gamut with a limited palette of primary colors, and/or the gamut is poorly structured (i.e., not a spheroid or obloid). The system uses an iterative process to identify the best color for a given pixel from a palette that is modified to diffuse the color error over the entire electro-optic display. The system additionally accounts for variations in color that are caused by cross-talk between nearby pixels.
IMAGE PROCESSING APPARATUS
The present disclosure relates to an image processing apparatus. The image processing apparatus according to an embodiment of the present disclosure includes a display having a plurality of pixels, and a controller, wherein the controller: calculates an average luminance value of a first frame of an image based on RGB data corresponding to the image; sets a criterion for determining an output level of the plurality of pixels according to the average luminance value of the first frame; controls the display to output a first frame group, including the first frame, according to the set criterion; calculates an average luminance value of a second frame of the image according to a predetermined cycle; resets a criterion for determining the output level of the plurality of pixels according to the average luminance value of the second frame; and controls the display to output a second frame group, including the second frame, according to the reset criterion. Accordingly, by dynamically changing the criteria for determining the output level of the plurality of pixels included in the display based on the luminance value of each frame of the image, the image may be displayed more clearly. Various other embodiments are possible.

Transmitting device, transmitting method, receiving device, and receiving method
Display with an appropriate luminance dynamic range is realizable on a receiving side. A gamma curve is applied to input video data having a level range from 0% to 100%*N (N: a number larger than 1) to obtain transmission video data. This transmission video data is transmitted together with auxiliary information used for converting a high-luminance level on the receiving side. A high-level side level range of the transmission video data is converted on the receiving side such that a maximum level becomes a predetermined level based on the auxiliary information received together with the transmission video data.
