摘要:
A 3D /2D multiprimary color image device is provided with an optical unit to direct one image to the left eye and another image to the right eye. Each color dot of the multiprimary color image device comprises at least two color sections controlled independently. To display a 3D image, one section of a color dot is for displaying a left eye image while another section of the same color dot is for displaying a right eye image. To display a 2D image, both sections of a color dot for the left eye and for the right eye displaying the same image independently.

Methods and apparatuses for color denoising are described. There is provided an image processing method. The method comprises the steps of retrieving chrominance level for a plurality of pixels in a predetermined configuration; computing a weight for each pixel; applying the weight to the chrominance level for each the pixel; summing the weighted chrominance level to output a chrominance level for a center pixel at the center of said predetermined configuration; and repeating the above steps for every pixel per image. The color noise can be reduced while preserving the edge without any edge detection.

Methods and systems for denoising embedded digital video decoding. Prediction and residue block of a current frame are obtained from motion vector. Variance of residue block is calculated using prior reference blocks, and a causal temporal linear minimum square error estimator is used to calculate a filter coefficient. The residue block is modified using the filter coefficient, and an output digital bitstream of blocks of pixels of the current frame is produced using the modified residue block and prior denoised prediction value of prior frames.

An image device and a data processing system. In order to process subpixel rendered RGB data such as Clear Type™ font data to be processed and put correctly on a non-RGB stripe image device such as a 2×2 matrix RGBW quad pixel image device, a matching 2×2 quad pixel image device is selected to cope with the corresponding input data triplet from the subpixel rendered RGB input data string. Since the blue dot carries the least luminance information in a white balance, Green/Blue/Red (GBR) triplet from the subpixel rendered input RGB data string is selected to match with a 2×2 matrix quadpixel image device where G and R dots of the 2×2 quad pixel have the maximum overlapping area with the corresponding G and R dots from the GBR stripe pixel data.

A method, apparatus and computer program product for correcting white balance in a digital image are described. The method comprises determining a number of grey blocks in the digital image (s102), each block comprising a subset of pixels of the image, and if the number of grey blocks is less than a predetermined value, scaling one or more color channels of the digital image using a first gain value to generate a first intermediate image (s201A) and scaling one or more color channels of the digital image using a second gain value to generate a second intermediate image (s201B). A number of grey blocks in each of the first and second intermediate images (s202A, s202B) is determined and the gain value resulting in the intermediate image having a greater number of grey blocks is set as the reference gain value (s203). A grey world process is performed on the intermediate image having a greater number of grey blocks (s205). Also described are a method, apparatus and computer program product for computing gain values for correcting a white balance of a digital image. The method comprises receiving an image divided into a number of blocks, removing the three most frequently occurring colors from the image (s204), and scaling one or more color channels of the image by respective reference gain values derived by a grey world process performed on the image.
