Abstract: An operating method of an image sensor may include generating first result image data based on performing first image capturing. The first result image data may include a plurality of first standard dynamic range (SDR) image data and first high dynamic range (HDR) image data. The operating method may include generating first parameters based on the first result image data. The first parameters may be associated with the first image capturing and may include a plurality of first exposure times and a plurality of first sensor gains. The operating method may include generating an adjustment factor based on the first parameters and generating second parameters based on adjusting the first parameters based on the adjustment factor. The second parameters may include a plurality of second exposure times and a plurality of second sensor gains. The operating method may include generating performing second image capturing based on the second parameters.

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.
