Abstract
An image-sensing device has pixel areas for outputting CCD signals of plural channels, and an adjusting portion for adjusting a level of each channel of the CCD signals outputted from the pixel area. A first channel CCD signal is provided from a pixel area 11a, a horizontal OB area 15a, a slide shift area 12a, and an HCCD 13a. A second channel CCD signal is provided from a pixel area 11b, a horizontal OB area 15b, a slide shift area 12b, and an HCCD 13b. Both of the first and second CCD signals are supplied to the adjusting portion with a reference signal added. The adjusting portion controls CCD signal of each channel by making the level of reference signal the same. The variation of the shift efficiency of electric charge in the border of pixel areas 11a and 11b for each channel, and in the slide shift areas 13a and 13b can be compensated.
