Abstract: One embodiment of the present invention sets forth a technique for generating and transmitting video frame data from a graphics processing unit (GPU) to a color field sequential display device. A frame buffer image comprising per-pixel packed color channels is transformed to a frame buffer image comprising regions corresponding to the color channels with vertical blanking regions inserted between color sub-field regions. Each region of the transformed frame buffer image is sequentially transmitted to the color field sequential display device for display of the corresponding color channel. Backlight illumination for each color channel is controlled by the GPU for temporal alignment with display of each color channel during a vertical blanking interval. The GPU may compensate an individual pixel's color channel value based on a corresponding previous color channel value in order to minimize crosstalk between neighboring color fields.

Abstract: In embodiments of power saving field sequential color (FSC), an illumination source illuminates pixels of a displayable image by sequentially generating RGB (red, green, blue) components of a pixel in a timed sequence of field sequential color. The pixels of a displayable image may also include a white component derived from the RGB components. An illumination reduction algorithm is implemented to determine the highest RGB (or RGBW) components from any of the pixels of the displayable image. The highest RGB (or RGBW) components can be determined from any combination of the same or different pixels of the displayable image. The illumination reduction algorithm then divides each of the highest RGB (or RGBW) components by a maximum brightness value to generate respective RGB (or RGBW) component factors. A display controller then processes each pixel of the displayable image for display according to the RGB (or RGBW) component factors.

Abstract: A mechanism for mitigating undesired color image breakup artifacts arising in display systems that exploit the principle of field sequential color generation. By suitably reducing the time interval during which image information strikes the moving retina, such that the differential position for the respective red, green, and blue components of the image falling upon the moving retina does not exceed the diameter of a retinal cone or rod, the cause of the breakup is negated and the image becomes unitary as expected: the eye sees the image as if all the components arrived at the same time. The truncation of light emission into shorter time frames necessitates a compensatory increase in imaging light intensity, such that the net amount of photonic flux striking the retina, averaged over time, remains unchanged. The mechanism can be applied to systems with discrete red, green, and blue sources as well as to color-wheel-based systems.

Abstract: A subject captured by a camera may be affected by environmental lighting provided by nearby light sources and the sun or moon, which may cause underexposure or overexposure of the image or aesthetically displeasing color tones. Image processing and camera adjustments may mitigate some imaging problems with limited effect and introduce undesirable side effects.

Moreover, the lighting array may be responsively controlled to adjust the subject image with respect to one or more target spectra specifying desirable colors for the subject image. The lighting array may be iteratively controlled, e.g. by a gradient descent algorithm, for incrementally adjusting parameters with respect to proximate target spectra for the image.

Preferably, a continuous scaling function is provided which smoothly approaches the minimum and maximum of the system's dynamic range for providing an aesthetically pleasing enhancement while maintaining true color.

Abstract: In a frame-by-frame color image pickup apparatus, images of light components transmitted through red, green, and blue filters of a rotating filter are introduced to an image pickup device arranged in an optical path with rotating filter. The cells in the image pickup device are grouped into cell blocks, each block made up of four cells arranged in one horizontal row and four vertical columns. The rotational speed of the rotating filter is increased, and the cells within each block selected by switches for reading are fixed when an image is dynamic, a quarter of all the cells are read at one cycle of revolution of the rotating filter, and the remaining cells are interpolated to form one frame image. Color breakup is thus precluded. When an image is still, the cells selected are switched at each cycle of revolution of the rotating filter, and all the cells are read over four cycles of revolution of the rotating filter. Thus, a high resolution color image is obtained.

Abstract: An encoder decomposes an input color image signal into a luminance signal and color signals, places the color signals in image memories, then fetches color signals of a given screen before and after. A detector calculates differences between the color signals to detect color misregistration either on a pixel basis or a block basis. On the other hand, color signals of a last image acquired before occurrence of color misregistration are stored in frame memories. When color misregistration is detected, a corrector reads the color signals of the last image from the frame memories, and produces correction signals. A counter carries out counting for each difference between color signals of given screens before and after, then detects a distribution of color misregistration of a screen. A selector checks the distribution of color misregistration of a screen to identify the cause of color misregistration, then selectively outputs either the input color image signal or a correction signal sent from the corrector.
