A time delay and integration(TDI) type CMOS image sensor is proposed to obtain RGB pattern real color image.Rolling exposure in along-track direction is applied to TDI technology
and the operating mode of readout after accumulation accelerates readout speed of image data.Red
green and blue color filters are circulation arranged to obtain real color image of objects
and color distortion is avoided.TDI algorithm in digital domain is deduced and verified.Experimental results show that PSNR increases by 3dB every 2 TDI stages.
