Abstract
An image processing apparatus and an image processing method are provided. The image processing apparatus includes a sample unit, an amplifier, an analog to digital converter, and a white balance unit. The sample unit is for sampling a pixel to obtain a pixel voltage. The amplifier is for amplifying the pixel voltage according to an analog gain. The analog to digital converter is for converting the amplified pixel voltage into digital pixel data, the digital pixel data including a number of first sub-pixel data which are corresponding to different colors. The white balance unit is for obtaining a number of second of sub-pixel data from white balance compensating the first sub-pixel data. The first sub-pixel data are white balance compensated respectively according to the analog gain and a number of white balance gains which are corresponding to different sub-pixels.
