Classic design summary based on CMOS or CCD image sensor

An image sensor, or photosensitive element, is a device that converts optical images into electrical signals that are widely used in digital cameras and other electro-optical devices. Early image sensors used analog signals, such as video camera tubes. Today, image sensors are mainly classified into two types: a charge-coupled device (CCD) and a complementary CMOS AcTIve pixel sensor. This article describes the application and technical literature based on CMOS or CCD image sensors for your reference.

Implementation of Fingerprint Identification Instrument Based on USB Transmission and CMOS Image Sensor

This article uses CMOS color digital image sensor USB control transfer chip (integrated with enhanced 51 core) to achieve fingerprint information acquisition and USB transmission, while the speed of the fingerprint sensor output data (27MB / s) and USB controller (AN2131QC) The data transfer rate (12Mb/s) is not matched, so the system uses SRAM and CPLD to form an intermediate cache.

Dual Image Sensor Design Based on FPGA

This article improves by using data from two image sensors; one example is the black box of the Car Driver Recorder (CDR), which is usually mounted near the rearview mirror and has two cameras. One camera is facing the windshield while the other camera is pointing at the driver. The video of the camera is stored in a local memory chip and can be retrieved if there is an accident or doubt.

Application of CCD Image Sensor in Low-light TV System

The CCD image sensitive unit can realize self-scanning and complete the conversion from optical signal to electrical signal. Such an electrical signal is usually a video signal conforming to the television standard, and can be restored to a visible image of an object on a television screen, or can be stored in a tape drive or input into a computer for image enhancement, recognition, storage, and the like. Therefore, the CCD device is an ideal imaging device.
