Image sensor and operating method thereof

An image sensor comprising:

• an image generating device including a plurality of pixels configured to generate a plurality of pixel signals, and the image generating device configured to generate first image data, the first image data including pixel codes of the plurality of pixels, based on the plurality of pixel signals;
• a channel deviation determination processor configured to receive the first image data, determine whether the first image data is channel deviation image data in which a channel deviation has occurred, calculate a determination parameter, based on the pixel codes, in response to the first image data being channel deviation image data, and determine at least one channel deviation region within the first image data, based on the calculated determination parameter;
• and
• a pre-processor configured to generate second image data by correcting the at least one channel deviation region of the first image data, based on the determination parameter,
• the channel deviation determination processor configured to calculate a saturation ratio of the first image data, based on the pixel codes, and determine the first image data to be channel deviation image data, based on the saturation ratio being greater than or equal to a threshold ratio.

An operating method of an image sensor including a plurality of pixels, the operating method comprising:

• generating first image data including pixel information, based on a plurality of pixel signals generated by the plurality of pixels;
• determining whether the first image data is channel deviation image data in which a channel deviation has occurred, based on the pixel information;
• calculating a determination parameter, based on the pixel information, in response to the first image data being the channel deviation image data
• determining at least one channel deviation region within the first image data, based on the determination parameter;
• and
• generating second image data by correcting the at least one channel deviation region, based on the determination parameter,
• the pixel information including pixel codes of the plurality of pixels.
