Abstract
A method, an image sensor, and an image processing device for crosstalk noise reduction are proposed. The method is applicable to an image sensor having a sensing array of image sensing elements and PD sensing elements and includes the following steps. A raw image generated by the sensing array is obtained. Whether to compensate image data of a current image pixel among image pixels corresponding to the image sensing elements is determined based on a first condition associated with at least one of an exposure and a system gain of the image sensor, a second condition associated with pixel coordinates of PD pixels corresponding to the PD sensing elements, and a third condition associated with sharpness information of the raw image. The image data of the current image pixel is compensated in response to the three conditions being satisfied. A processed raw image including the compensated image data is generated.
