Camera module for calibrating image data, operating method of camera module, and electronic device including camera module

An operating method of a camera module, the method comprising;

• outputting raw image data, by an image sensor including a plurality of pixels included in the camera module;
• and
• generating crosstalk calibration data, by control logic included in the camera module,
• wherein the generating the crosstalk calibration data includes:
• turning off calibration of the image sensor in response that an amount of light measured by the image sensor is less than or equal to one threshold value and that a value indicating a distance between a depth sensor and a display detected by the depth sensor is less than or equal to another threshold value;
• after turning off the calibration of image sensor, receiving first raw image data from the image sensor;
• obtaining first code values respectively corresponding to first output values included in the first raw image data from among code values respectively corresponding to output values of the image sensor based on first color temperature data from the first raw image data;
• generating a first ratio value group of the first output values for each of the first code values;
• generating the crosstalk calibration data based on the first ratio value group;
• and
• after generating the crosstalk calibration data based on the first ratio value group, turning on the calibration of the image sensor.

An electronic device comprising:

• a camera module;
• a display through which light is incident onto the camera module;
• and
• an application processor configured to receive image data from the camera module and to output an output image,
• wherein the camera module includes:
• a memory;
• a depth sensor configured to detect a distance from the display and to generate a distance value;
• an image sensor including a plurality of pixels outputting raw image data;
• and
• control logic configured to receive the raw image data and to generate image data, wherein the image sensor is configured to:
• output first raw image data including first color temperature data based on light incident from the display, and
• wherein the control logic is configured to:
