Abstract
A new method and device to generate two field of view images from a sensor pixel array is achieved. The method comprises providing an array of sensing pixels. An array digital data stream is generated by sequentially generating a plurality of digital data streams each corresponding to blocks of the sensing pixels in the array. All the sensing pixels in any block are sampled simultaneously. First and second digital video streams are generated from the array digital data stream. The first and second digital video streams comprise first and second fields of view of the array, respectively. Each pixel of the first digital video stream corresponds to a filtered and sub-sampled combination of more than one of the sensing pixel samples.
