Document Type and Number:
Japanese Patent JP4991494
Kind Code:
B2
Abstract:
An image pickup apparatus is provided that is capable of obtaining a correction value effective for horizontal noise correction, while suppressing increase in chip area of an image pickup device. The image pickup apparatus includes an image pickup device (101) for converting an object image into electrical signals, and a correcting section for correcting a picked-up image. The image pickup device includes a pixel signal readout circuit (204) for reading out pixel signals from a pixel region on a line-by-line basis via vertical signal lines, a dummy signal readout circuit (209) for reading out dummy signals, and a horizontal transfer circuit (205) for transferring outputs of the pixel signal readout circuit and the dummy signal readout circuit. The correcting section corrects the outputs of the pixel signal readout circuit on a line-by-line basis using the outputs of the dummy signal readout circuit.
