Image inputting apparatus |
摘要 |
All electric charges accumulated in a line sensor are transferred via a first shift gate to a first analog shift register. By controlling the width of a shift pulse signal to be supplied to a second shift gate, the amount of an electric charge transfer when the electric charges on the first analog shift register are transferred to a second shift register is controlled. As a result, the amount of the electric charges on the first analog shift register is controlled to a desired value. Accordingly, the amplitude of an image signal outputted from the first analog shift register can be easily adjusted. Further, the sensitivity of a CCD line sensor and variation of light amount of a light source can be corrected.
