This paper presents a new image sensor with programmable multiresol~~tion rearlout capability. The proposed image sensor can o11tp11t data at varying resolutions. Differing to our previollsly reported spatially variant snnlpling sensor which sub-samples witho ~ ~ t filtering[l], in the m~lltiresollltion sensor, 11locks of the pixels are averaged and read out then, the new sensor does not suffer...

In this paper we present a low power temporaldifference image sensor with wireless communication capability designed specifically for imaging sensor networks. The eventbased image sensor features a 64×64 pixel array and can also report standard analog intensity images. An ultra-wideband (UWB) radio channel allows to transmit digital temporal difference images wirelessly to a receiver with high ...

An imaging system includes an array of lenses, a plurality of sensor pixels for each lens, the sensor pixels being on an image plane of the imaging system, and a corresponding plurality of focal plane coding elements. A focal plane coding element for each sensor pixel has multiple sub-pixel resolution elements. The focal plane coding element being between the lens and each sensor pixel, wherein...

In this paper a new rail-to-rail pixel readout architecture is proposed to enhance the performance of CMOS image sensor for both low voltage and low power applications. Due to this new readout circuit, the enough input voltage swing under a low supply voltage is achieved and guaranteed for correct successive signal processing. As a consequence, the ability of working under a lower voltage using...

In this paper, we show anew image sensor for measuring traffic flow. The image sensor is set at an intersection. The image sensor measures t r af f i c flow by vehicle tracking. The tracking is done by gray level pattern matching. Gray level pattern matching is suitable for outdoor use since it is robust against change of scene brightness. Then we provide the hardware for high speed gray level ...

The image sensor is the most important part of video and still image processing line in digital video or still camera. Data of CMOS process will produce noise in long transmission distance; therefore it must first be amplified and integrated each pixel data. The choice of medium and apparatus for transmitting image and the other the control signal will be directly related to the quality and rel...
