Solid-state imaging apparatus |
摘要 |
A solid-state imaging apparatus includes a pixel array, an effective signal line, a dummy pixel, a dummy signal line, and a processing unit. The effective pixels in the pixel array include a photoelectric converter, a charge-voltage converter, and an output unit. The dummy pixel includes a charge-voltage that has the same configuration as the charge-voltage converter of the effective pixel, and an output unit. A shortest distance between the charge-voltage converter of the dummy pixel and the effective signal line is longer than a shortest distance between the charge-voltage converter of the dummy pixel and the dummy signal line. |

1. A solid-state imaging apparatus, comprising:
a pixel array having a plurality of effective pixels arranged in an array; an effective signal line to which a signal of a plurality of effective pixels aligned in a first direction is output; a dummy pixel provided with respect to the plurality of effective pixels aligned in the first direction; a dummy signal line to which a signal of the dummy pixel is output; and a processing unit configured to correct the signal from the effective signal line, based on the signal from the dummy signal line, wherein the effective pixels include a photoelectric converter, a charge-voltage converter configured to convert a charge generated in the photoelectric converter into voltage, and an output unit configured to output a signal corresponding to the voltage of the charge-voltage converter, to the effective signal line, the dummy pixel includes a charge-voltage converter that has the same configuration as the charge-voltage converter of the effective pixel, and an output unit configured to output a signal corresponding to voltage of the charge-voltage converter of the dummy pixel, to the dummy signal line, and a shortest distance between the charge-voltage converter of the dummy pixel and the effective signal line is longer than a shortest distance between the charge-voltage converter of the dummy pixel and the dummy signal line. |
