Imaging sensor having reduced column fixed pattern noise |
摘要 |
An imaging sensor having reduced column fixed pattern noise includes a plurality of imaging pixels and a column sampling circuit. The plurality of imaging pixels are arranged in a column the column sampling circuit is coupled to the column. A plurality of sampling channels are included in the column sampling circuit, where the column sampling circuit randomly selects a first sampling channel from among the plurality of sampling channels to sample a first data signal from a pixel included in the plurality of imaging pixels and where the column sampling circuit randomly selects a second sampling channel from among the plurality of sampling channels to sample a second data signal from the pixel. |
