1. An operating method of an image sensor, the operating method comprising:
generating first result image data including a plurality of first standard dynamic range (SDR) image data and first high dynamic range (HDR) image data based on performing first image capturing;
generating first parameters, which are associated with the first image capturing and include a plurality of first exposure times and a plurality of first sensor gains, based on the first result image data;
generating an adjustment factor based on the first parameters;
generating second parameters including a plurality of second exposure times and a plurality of second sensor gains based on adjusting the first parameters based on the adjustment factor; and
performing second image capturing based on the second parameters.
