Abstract:
1. An image input apparatus comprising: a light source having a white spectral characteristic; a 4-line CCD sensor having a monochromic reading line sensor section composed of a monochromic photodiode array, a monochromic shift gate, a monochromic analog shift register, and a monochromic amplifier which has an amplification factor set according to the spectral characteristic of the light source and which amplifies an electric signal from the monochromic analog shift register with this amplification factor to output the amplified electric signal to an exterior, a color reading line sensor section composed of color photodiode arrays, color shift gates, color analog shift registers, and color amplifiers each of which has an amplification factor set according to the spectral characteristic of the light source and which amplifies an electric signal from the color analog shift register with this amplification factor to output the amplified electric signal to the exterior; and a control circuit, which controls the 4-line CCD sensor.
