Modular CMOS imaging system

Abstract

The invention relates to a modular CMOS imaging system, which aims to solve such problems as a large designing workload, a long processing cycle and high cost of the conventional imaging system of CMOS image sensors. The modular CMOS imaging system comprises a CMOS image sensor focal plane unit and a video processing unit, wherein the CMOS image sensor focal plane unit and the video processing unit are connected through a connector; and the CMOS image sensor focal plane unit comprises a CMOS image sensor, a clock switching circuit, a digital signal shaping and level converting circuit, a vertical driving circuit, and a power switching circuit. When the imaging system is applied to different CMOS sensors, only the corresponding CMOS image sensor focal plane units need to be replaced, and replacement of the video processing unit is avoided, so that the work cycle is greatly shortened, the cost is greatly lowered, and the designing risk is reduced; and power supplies of the CMOS image sensors are classified into multiple types, and two or more adjustable power supplies are used to respectively supply power, so that the power efficiency is improved, the total power consumption is reduced, and thermal deformation of an optical-mechanical structure caused by heating of a focal plane sensor is alleviated.

Description

Technical field [0001] The present invention relates to a modular CMOS imaging system, in particular to a universal modular imaging system compatible with multiple CMOS image sensors such as area array, single-spectrum linear array, multi-spectral linear array, TDICMOS and the like. Background technique [0002] There are many types of CMOS image sensors, including area arrays and linear arrays; linear arrays are divided into multi-spectral and single-spectrum, and can also be divided into TDI working mode devices and non-TDI working mode devices. Different CMOS image sensors require different types and quantities of operating voltages, and require different input clock types, control signals and output data methods. If a specific imaging system is designed for each CMOS image sensor, there will be a design workload Large, long processing cycle and high cost.
