Abstract: In one embodiment, a light sensor includes four cell arrays, one for each color of the Bayer pattern, and four lenses each focusing the light coming from the scene to be captured on a respective cell array. The lenses are oriented such that at least a second green image, commonly provided by the fourth cell array, is both horizontally and vertically shifted (spaced) apart by half a pixel pitch from a first (reference) green image. In a second embodiment, the four lenses are oriented such that the red and blue images are respectively shifted (spaced) apart by half a pixel pitch from the first or reference green image, one horizontally and the other vertically, and the second green image is shifted (spaced) apart by half a pixel pitch from the reference green image both horizontally and vertically.

Abstract: An image generating pipeline (IGP) includes a digital signal processor for implementing processing blocks connected in cascade for processing an input image that includes an array of raw pixel values to generate a color image that includes an array of reconstructed pixel values. A memory is coupled to the digital signal processor for storing the raw pixel values and the array of reconstructed pixel values. The digital signal processor includes a data cache, and the raw pixel values of the input image are processed through the processing blocks in sub-arrays having fractional dimensions of the pixel dimensions of the whole image array. The sub-arrays include an input sub-array of pixel values being loaded from the memory for defining a working window. The sub-arrays of raw pixel values have a row-wise dimension of at least a fraction of a full row of the input image, and a column-wise dimension equal to or larger than a column-wise filtering action of a respective processing block to which the input sub-array is input. The digital signal processor outputs at least one fraction of full rows of completely reconstructed pixel values of the input image for storing in the memory.
