摘要 |
A fixed pattern noise removal circuit is provided for removing vertical streak fixed pattern noise from an output signal of an image sensor including an output system for every predetermined number of columns. The fixed pattern noise removal circuit includes a correction signal output unit configured to output a correction signal corresponding to the output system in accordance with an offset component and a light-intensity-dependent component of the fixed pattern noise occurring in the output system, and a signal correction unit configured to remove the fixed pattern noise from the output signal of the image sensor on the basis of the correction signal output from the correction signal output unit. |
