Patent ID: 11064134

Abstract:
An image sensor includes a pixel array, and a first, second, and an intermediate memory-element. The memory-elements store, respectively, a first, second, and an intermediate exposure value. The pixel array includes pixel-subarrays each including a rescue pixel and a first, second, and third plurality of contiguous pixels. Each of the first plurality of pixels is connected to the first memory-element and spans diagonally-opposite corners of the pixel-subarray. Each of the second plurality of pixels is connected to the second memory-element and located on a first side of the first plurality of pixels. Each of the third plurality of pixels is connected to the second memory-element and located on a second side of the first plurality of pixels. The rescue-pixel is connected to the intermediate memory-element and is (i) located on one of the first side and the second side and/or (ii) adjacent to one of the first plurality of pixels.
