Abstract: Suppress deterioration in picture qualities while achieving expansion in a dynamic range. An image sensor readout method that reads out, from an area sensor where a plurality of image pickup elements are arranged in matrix, signal charges that are accumulated in the image pickup elements is constituted as follows. First, plural kinds of exposure time different in length from each other are set, and the exposure time is then individually allocated to each line of the area sensor. Next, the signal charges accumulated in the image pickup elements in the allocated exposure time are read out through a line unit of the area sensor. Then, the read out signal charges are synthesized through a screen unit of the area sensor.

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.
