IMAGE PICKUP APPARATUS |
摘要 |
An image pickup apparatus that makes it possible to achieve both high picture quality and a wide dynamic range is provided. Each pixel unit included in the image pickup apparatus includes: four photodiodes; four transfer transistors; a charge storage portion (four floating diffusions) for storing electric charges generated at the photodiodes; an amplification transistor; a select transistor; and a reset transistor. The image pickup apparatus further includes multiple coupling transistors. Each coupling transistor couples together the charge storage portions of two pixel units of the pixel units. A scanning circuit switches on or off the coupling transistors according to read mode.
