Abstract
The present invention provides an image adjustment method and associated image processing circuit for performing the following operations upon each pixel of an image: obtaining R, G, B values and infrared ray (IR) value corresponding to the current pixel; generating multiple initial compensation parameters corresponding to the R, G, B values; generating an over-compensation parameter according to the R, G, B and IR values; comparing the over-compensation parameter with at least one threshold value to generate a compensation adjustment coefficient; and performing IR crosstalk compensation upon the image with the compensation adjustment coefficient.
