Patent Images
1. A device comprising:
- an array of sensors configured in a row-column format to capture image data through a color filter having different color filter components;
an array controller configured to select subsets of the sensors for readout, wherein a group of multiple sensors in a column of sensors are included in each of a plurality of the subsets of the sensors; and
a compensation system configured to compensate the image data readout from the subsets of the sensors based on the color filter components associated with the sensors in the subsets of sensors.
