Abstract
A reference charge generator provided on an image capture element generates reference charge. The reference charge is transferred through a vertical transfer section as is signal charge of a pixel which is generated by a photoelectric converter. A reference signal corresponding to the reference charge is output from the image capture element. Data of a digital value obtained by conversion from the reference signal and a digital value which is obtained from the reference signal when the image capture element ideally operates are compared to estimate the state of a pulse for driving the image capture element. The state of the pulse is adjusted such that the pulse has optimum phase and duty.
