Patent ID: 7379105

Claim:
A video image capture device, comprising: an image sensor comprising a two-dimensional array of pixel elements overlaid with a pattern of a given number of selectively transmissive filters and having a first vertical resolution being an intermediate vertical resolution of vertical resolutions specified for a group of video formats, said image sensor outputting digital pixel data representing an image of a scene; a frame buffer, in communication with said image sensor, for storing said digital pixel data; and an interpolator module, in communication with said frame buffer, for interpolating said digital pixel data by upsampling or downsampling in the vertical direction only to generate video data in at least three color planes and having a second vertical resolution corresponding to a video format selected from said group of video formats; wherein said interpolator module applies at least one combined filter for interpolating said digital pixel data into video data in a first color plane and having said second vertical resolution, said combined filter incorporating a demosaic filter and a scaling filter, and wherein said demosaic filter is an n×n′ convolution kernel where n=n′ or n≠n′, said scaling filter is a 1×m convolution kernel, and said combined filter is an n×(n′+m−1) convolution kernel.
