Method for Compressive sensing using high-order sigma-delta modulator for Image sensor and an Image sensor using high-order sigma-delta modulator

摘要

An embodiment is a method of applying a high-order delta-sigma modulator to a compression sensing image sensor, selecting a series of pixel groups based on a measurement matrix from an array in the image sensor, and individual pixels in the selected group are input to the delta-sigma modulator It may include deriving a solution of the partitioning problem and applying it to determine the order in which it is obtained, deriving a sampling order, and performing oversampling according to the sampling order derived using the partitioning algorithm, and a high-order delta - The more sigma modulators are used, the higher the sampling rate can be.
