PROBLEM TO BE SOLVED: To provide an imaging device which suppresses the frequency of the charge shift clock of an HCCD low, and performs photographing with good image quality over the whole area of a screen. SOLUTION: An output signal from a left channel comprising a pixel region 11a, a horizontal OB portion 15a, an oblique shift region 12a, and an HCCD 13a, and an output signal from a right channel comprising a pixel region 11b, a horizontal OB portion 15b, an oblique shift region 12b, and an HCCD 13b, are supplied to a comparison adjustment portion. To the signals of both channels, vertical reference signals by the function of a vertical charge injection portion 17 are added, and the comparison adjustment portion adjusts the level of the output signal of each channel, so that the levels of the vertical reference signals of both channels become the same. Consequently, variations of charge shift efficiencies of regions near the boundaries of both channel portions, the oblique shift regions 12a and 12b, etc., can be excellently corrected.
