PROBLEM TO BE SOLVED: To reduce an influence of a correlation noise in a supplementary image concerning various modalities.SOLUTION: A device generates a portion of an image from a plurality of channels in a row by sampling each channel during a sampling time, offsets sampling times of different channels in the row, thereby reducing noise correlation among the channels. Pixel sampling times may be defined by start times of the channels within the row, end times or both. Offsetting may be accomplished using a predetermined set of sampling time values or by randomizing sampling time values. Offsetting pixel sampling times relative to each other decorrelates channel sampling because different phases of the noise signal are sampled on each channel, effectively dithering the channel noise within each row. Random sampling within the channel, such as by varying a channel sampling time between rows, further dithers the noise within each channel. |
