CMOS image sensor for spatiotemporal image acquisition
We present a 6464-pixel CMOS image sensor chip that can acquire a 16-gray-level image containing both spatial and temporal information of the moving luminous object under observation. The image can next be processed using any image processing software in order to determine the speed, trajectory, and direction of motion of the moving object. The architecture of the sensor and an example of its a...
متن کاملEmbedded ARM9 Image Acquisition System Based on CMOS Image Sensor
This article is based on CMOS image sensor which is commonly used in image acquisition. It applies 32-bit ARM9 microprocessor S3C2410A as the CPU to control other function modules and designs embedded Arm9 image acquisition system for the realization of machine vision. The main function modules are SDRAM memory cell, image acquisition unit and Ethernet transmission module, UART serial port comm...
متن کاملCurrent-Mode CMOS Image Sensor
This thesis presents a current-mode CMOS image sensor using lateral bipolar phototransistors (LPTs). The objective of this design is to improve the photosensitivity of the image sensor, and to provide photocurrent amplification at the circuit level. Lateral bipolar phototransistors can be implemented using a standard CMOS technology with no process modification. Under illumination, photogenerat...
متن کاملCMOS Active Pixel Image Sensor
This paper addresses the development of a micropower 176 144 CMOS active pixel image sensor that dissipates one to two orders of magnitude less power than current state-of-the-art CMOS image sensors. The chip operates from a 1.5-V voltage source and the power consumption measured for the chip running from an internal 25.2-MHz clock yielding 30 frames per second is about 550 W. This amount enabl...
