Image sensors and methods of operating the same

An electronic device, comprising:

• image processor circuitry and an image sensor,
• wherein
• the image processor circuitry is configured to transmit, to the image sensor, gain information indicating an intensity of light concurrently with the image sensor generating an image at a pixel array of the image sensor based on the light being incident to one or more pixels of pixel array, and
• the image sensor includes image sensor processing circuitry configured to control a switch to be turned on/off to change an electrical path of a current that passes through pixel load circuitry of the image sensor based on the pixel array generating the image, based on the gain information.

A method of operating an image sensor, the method comprising:

• receiving, from image processor circuitry, gain information indicating an intensity of light concurrently with generation of an image at a pixel array of the image sensor based on the light being incident to one or more pixels of pixel array;
• and
• controlling a switch of the image sensor to be turned on/off to change an electrical path of a current that passes through pixel load circuitry of the image sensor based on the pixel array generating the image, based on the gain information,
• wherein the switch is connected to a node between a plurality of transistors of the pixel load circuitry that are serially connected to each other.
