Abstract: An operation method of an image sensor includes detecting a motion region based on a first image and a second image to obtain a detected motion region, the first image corresponding to a first exposure time and the second image corresponding to a second exposure time, the second exposure time being shorter than the first exposure time, determining a weight for the detected motion region, performing signal pre-processing on the first image to generate a pre-processed image, and outputting a third image based on the pre-processed image and the weight.

Abstract: An imaging system includes an image sensor configured to obtain first image data, based on a received light; and a processing circuit configured to determine an operating mode of the image sensor, among a first mode and a second mode, based on an illumination and a dynamic range corresponding to the obtained first image data. The image sensor includes a first sub-pixel configured to sense a target light corresponding to a target color, in the first mode, convert the target light sensed during a first exposure time, into a first signal, and in the second mode, convert the target light sensed during a second exposure time longer than the first exposure time, into a second signal.
