Image sensor processing merged image and image processing system comprising the same

Abstract

An image sensor includes a pixel array and a readout circuit that generates a first image of an object based on a first exposure time, a second image of the object based on a second exposure time, and a third image of the object based on a third exposure time, the first exposure time, the second exposure time, and the third exposure time being different from each other and the second exposure time and the third exposure time are shorter than the first exposure time, a pre-processor that performs linearization processing on the second image and the third image to generate a merged image with an increased number of bits of a pixel value, and an interface circuit that outputs first image data based on the first image and second image data based on the merged image to an external processor.
