摘要： An imaging device including: image generation pixels generating signals for image generation; and phase difference detection pixels generating signals for focus alignment determination by phase difference detection is disclosed. The first lines where the image generation pixels are arranged in a specific direction and second lines where the phase difference detection pixels are arranged in the specific direction are alternately arranged in a direction perpendicular to the specific direction. The image generation pixels and the phase difference detection pixels are alternately arranged so that the image generation pixels constituting the first line and the phase difference detection pixels constituting the second line adjacent to the first line overlap by portions thereof in the perpendicular direction.

摘要： Imaging signal obtained through exposure for divided exposure times is A/D converted to digital imaging signal. Dark current component is subtracted from the digital imaging signal. The result of subtraction is accumulated and stored in a first memory. Next, exposure for divided exposure times is performed with the imaging device shielded from light. The obtained imaging signal is A/D converted to digital imaging signal. Dark current component is subtracted from the digital imaging signal. The result of subtraction is accumulated and stored sequentially in a second memory. The digital imaging signal stored in the second memory is subtracted from the digital imaging signal stored in the first memory. Then the result of subtraction is output. The word length allocated to one pixel in the first and second memories is longer than the word length of one A/D converted pixel.
