A computational pixel imaging system has been granted a patent (Publication Number: US11974049B2) that includes a computational pixel imager with a plurality of pixels, each equipped with a detector, a detector biasing line, one or more counters, and a mixer. The system utilizes a light source to illuminate objects and a modulation source to adjust light intensity. The difference between the modulation frequencies is crucial, falling within a range of 10 kHz to 500 kHz. The system's innovative design allows for precise control over count-up and count-down cycles, enabling advanced image processing capabilities.

Moreover, the patent also covers a method for down-sampling using a pixel integrated circuit, involving illuminating objects with modulated light, receiving the light with a detector, and modulating bias or supply with a different frequency. The method includes digitizing signals using counters and controlling the periodicity of count-up and count-down cycles. Additionally, a multi-thread processing method within the pixel array is detailed, where different computational algorithms are simultaneously applied to process image data. These methods, along with the unique design of the computational pixel imager, offer enhanced image processing functionalities, including spatial and temporal filtering, convolution, correlation, image shift operations, and background subtraction. The system's ability to handle infinite dynamic range counting further enhances its utility in various imaging applications.
