Image processing method and image processing apparatus which can perform background noise removing based on combined image

摘要

An image processing method, applied to an image processing apparatus comprising a light source and an image sensor. The image sensing method comprises: acquiring a first image via the image sensor if the light source operates in a first mode; acquiring a second image via the image sensor if the light source operates in a second mode; acquiring a third image via the image sensor if the light source operates in the first mode; generating a combined image based on the first image and the third image; and acquiring a target image after background noise removing based on the second image and the combined image.
