1. An image sensor, comprising:
a pixel group including a first region and a second region; and
a color filter having a first color on the pixel group, wherein:
the first region includes a first pixel including a first photodiode, a first floating diffusion region on the first photodiode, and a first transfer transistor on the first photodiode,
the second region includes a second pixel including a second photodiode, a second floating diffusion region, and a second transfer transistor connected to the second photodiode and the second floating diffusion region,
each of the first pixel and the second pixel are arranged in an m*n arrangement, wherein m and n are natural numbers of 2 or more, such that at least four first pixels are in the first region and at least four second pixels are in the second region, and at least four first photodiodes are in the first region and at least four second photodiodes are in the second region,
in plane view, a total first photodiode area in the first region is greater than a total second photodiode area in the second region, and
in plane view, the first region surrounds the second region.
