ABSTRACT:
An image data processing apparatus is provided for crisply reading a dark portion on an original. The image data processing apparatus includes a light source for applying a light ray to an original, a CCD sensor for receiving a light reflected by the original, converting the light into an electric signal and storing the electric signal, an analog processing circuit for receiving the electric signal from the CCD sensor and correcting the DC level of the electric signal, an analog-to-digital converter for receiving a corrected electric signal from the analog processing circuit and converting the corrected electric signal into a digital signal, a digital processing circuit for reading the digital signal from the analog-to-digital converter two or more times and adding the digital signal into one output signal, and a control section for controlling the CCD sensor, the analog processing circuit, the analog-to-digital converter and the digital processing circuit.
