چکیده

This paper presents a 64×64 CMOS image sensor with on-chip moving object detection and localization capability. Pixel-level storage elements (capacitors) enable the sensor to simultaneously output two consecutive frames, with temporal differences digitalized into binary events by a global differentiator. An on-chip, hardware-implemented, clustering-based algorithm processes events on the fly and localizes up to three moving objects in the scene. The sensor can automatically switch to region of interest mode and capture a picture of the object. The proposed image sensor was implemented using UMC 0.18 μm CMOS technology with a die area of 1.5 mm × 1.5 mm, and power consumption was only 0.4 mW at 100 FPS.

New Method for Analysis of image sensor to produce and evaluate the image

In this paper, a new method for evaluating CMOS image sensors based on computer modeling and analysis is introduced. Image sensors are composed of different parts, each of which has a specific effect on image quality. Circuits of image sensors can be evaluated and analyzed using circuit simulators or theoretically, but these methods cannot help to produce the final image. In order to produce th...

An APS With 2-D Winner-Take-All Selection Employing Adaptive Spatial Filtering and False Alarm Reduction

An active pixel sensor (APS) with two-dimensional winner-take-all (WTA) detection is presented. This system-on-a-chip employs adaptive spatial filtering of the processed image, with bad pixel elimination and false alarm reduction in case of a missing object. The circuit has a unique ability of adaptive spatial filtering that allows removal of the background from the image, one stage before it i...

CMOS Active Pixel Sensor with On-Chip Successive Approximation Analog-To-Digital Converter

The first CMOS active pixel sensor (APS) with onchip column-parallel successive-approximation analog-to-digital converter (ADC) is reported. A 64 64 element CMOS APS implemented in a 1.2m n-well single-poly, double-metal process with 24m pixel pitch is integrated with a 64 1 array of column parallel successive approximation 8-b ADC’s. Good image quality was observed. The capacitively-coupled AD...

A 600-dpi Capacitive Fingerprint Sensor Chip And Image-synthesis Technique - Solid-State Circuits, IEEE Journal of

This paper examines the possibility of a low-cost, high-resolution fingerprint sensor chip. The test chip is composed of 64 256 sensing cells (chip size: 2.7 10.8 mm2). A new detection circuit of charge sharing is proposed, which eliminates the influences of internal parasitic capacitances. Thus, the reduced sensing-capacitor size enables a high resolution of 600 dpi, even using a conventional ...
