26 Claims

1. An imaging system, comprising:

a plurality of optical sensors on an integrated circuit, wherein the plurality of optical sensors are arranged in an array, wherein the array comprises a plurality of rows and a plurality of columns;

a plurality of sets of optical filters configured in a layer having a respective top surface and a respective bottom surface, wherein the bottom surface of the plurality of sets of optical filters is located proximal to the plurality of optical sensors, wherein each optical filter of a set of optical filters is configured to pass light in a different wavelength range;

an interface configured to interface and communicate with the plurality of optical sensors;

memory that stores operational instructions;

processing circuitry operably coupled to the interface and to the memory, wherein the processing circuitry is configured to execute the operational instructions to:

sample an image in a first mode; and

sample at least a portion of the image sequentially on a row-by-row basis at a predetermined sampling rate in a second mode to produce row-by-row sample outputs, wherein the processing circuitry is further configured to initiate sampling at least some rows of the plurality of rows of optical sensors using different time stamps.
