Solid-state image pickup device and camera system |
摘要 |
A solid-state image pickup device including a pixel section arranged with multiple pixel circuits in matrix having functions for converting an optical signal to an electrical signal and for accumulating the electrical signal depending on an exposure time, and a pixel driving section capable of driving through a control line to reset, accumulate, transfer, and output signal electric charge of the pixel section. The pixel section may have a pixel shared structure arranged with one selection control line, one reset control line, and multiple transfer control lines, including a readout-pixel section and an unread-pixel section in its entirety. The pixel driving section includes a pixel control section where an unread-pixel is normally fixed in a reset state. When reading a readout-pixel in a shared relationship, if its address is selected or a selection signal becomes active, the unread-pixel reset-state is cancelled to turn into an unread state. |

1. A solid-state image pickup device comprising:
a pixel section including a plurality of pixels, each pixel having at least one photoelectric conversion element; and a pixel driving section configured to control the pixel section; wherein,
the pixel section includes two or more pixels which share at least one transistor element and when the pixels are driven at least one becomes a readout pixel and at least one becomes an unread pixel, andthe pixel driving section is configured to set a reset state for the unread pixel and when reading an electrical charge from the readout pixel which shares the same transistor element cancel the reset state of the unread pixel to place the unread pixel into an unread state. |
