Patent ID: 7242426

Claim:
A digital still camera, comprising: a solid state image pickup device for reading signal charges accumulated in imaging pixels and transferring said signal charges along a vertical transfer path, wherein color filters of said imaging pixels are horizontally arranged so as to form same patterns on every other line; a shooting mode selector for selecting either a low sensitivity mode or a high sensitivity mode; an image pickup device driver for, when said shooting mode selector selects said low sensitivity mode, reading signal charges from said image pickup device in the full-pixel reading mode, and for, when said shooting mode selector selects said high sensitivity mode, reading signal charges from said image pickup device in two or more even-numbered field reading modes; and a current controller controlling a strength of current supplied to an output signal amplification circuit provided at a final stage of the image pickup device or for controlling a strength of current supplied to a current amplification circuit connected to an output terminal of the image pickup device or both, wherein when the current controller controls the strength of the current supplied to the output signal amplification circuit, the current controller controls the strength of the current supplied to the output signal amplification circuit when the shooting mode selector selects the high sensitivity mode to be less than the strength of the current supplied to the output signal amplification circuit when the shooting mode selector selects the low sensitivity mode, and wherein when the current controller controls the strength of the current supplied to the current amplification circuit, the current controller controls the strength of the current supplied to the current amplification circuit when the shooting mode selector selects the high sensitivity mode to be less than the strength of the current supplied to the current amplification circuit when the shooting mode selector selects the low sensitivity mode.
