Abstract
An image pickup apparatus configured to pick up a still image includes an image pickup device having a plurality of pixels to convert an object image formed by an optical system to an electric charge. A pixel reading circuit operates in either a first reading mode for reading electric charges obtained from the respective pixels of the image pickup device on a pixel by pixel basis or a second reading mode for adding and reading the electric charges obtained from the respective pixels of the image pickup device. A controller evaluates camera shake during exposure. When an evaluation level of the shake is greater than a predetermined level, this controller controls the pixel reading circuit to operate in the second reading mode. when the evaluation level is smaller than the predetermined level, the controller controls the pixel reading circuit to operate in the first reading mode.
