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.

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

Provided is an image sensor including: a pixel array including a plurality of pixel groups each including first pixels to which a first conversion gain is applied and second pixels to which a second conversion gain is applied; a readout circuit configured to receive a first pixel signal corresponding to the first pixels and a second pixel signal corresponding to the second pixels through a single readout with respect to each of the plurality of pixel groups, generate first image data, based on first pixel signals of the plurality of pixel groups, and generate second image data, based on second pixel signals of the plurality of pixel groups; and an image signal processor configured to generate output image data by merging the first image data and the second image data in units of a pixel group.

Image sensor, electronic device including the image sensor and configured to generate output image data based on high conversion gain pixel signals, and low conversion gain pixel signals, and operating method therof

An image sensor and an image processing system in which the image sensor includes a sensing unit configured to generate a plurality of images having different luminances with respect to a same object, a pre-processor configured to merge n images (n is a natural number equal to or greater than 2) except for at least one of the plurality of images to generate a merged image, and an interface circuit configured to output the at least one image and the merged image to an external processor.
