description Provided is an image sensor and an operation method of the image sensor. The image sensor includes a pixel array including a plurality of white pixels, a plurality of color pixels, and a plurality of auto focus (AF) pixels, a first shared pixel including the plurality of white pixels and the plurality of color pixels includes a first conversion gain transistor and a second conversion gain transistor configured to control a conversion gain of the first shared pixel, and a second shared pixel including some of the plurality of white pixels and the plurality of color pixels and at least one AF pixel includes a third conversion gain transistor and a fourth conversion gain transistor configured to control a conversion gain of the second shared pixel. The first conversion gain transistor, the second conversion gain transistor, the third conversion gain transistor, and the fourth conversion gain transistor are connected to different conversion gain control lines, respectively.
