Abstract:
An image processing device is provided which comprises an input unit and an analog front end circuit with DC inputs. According to the invention, no capacitor is installed in the input unit and no clamper is installed in the AFE circuit with DC inputs. By appropriately selecting a comparing voltage and adding a level shifter or a compensation circuit, the invention can still generate an accurate digital signal.
