This paper proposes a 240 frames/s 2.1 M-pixel CMOS image sensor with column-shared cyclic ADC that consumes low power of 90 μW/column at 1.5 V supply and is applicable to the fine pixel pitch of 2.25 μm. The prototype sensor was fabricated in a 0.13-μm 1P4M CMOS technology. The measured DNL and INL are +0.59/-0.83 LSB and +2.8/-3.6 LSB, respectively. The measured maximum pixel rate is 500 Mpix...

This paper presents a new high speed simulation methodology to solve the long simulation time problem of CMOS image sensor matrix. Generally, for integrating the pixel matrix in SOC and simulating the system performance, designers try to model the pixel in various modeling languages such as VHDL-AMS, SystemC or Matlab. We introduce a new alternative method based on spice model in cadence design...

This paper reports recent results of a direct-detection X-ray CMOS image sensor for X-ray Free-Electron Laser (XFEL) experiments. The sensor incorporates the in-pixel dual gain circuitry by using Fully Depleted-Silicon-On-Insulator (FD-SOI) CMOS transistors located on top of the buried oxide (BOX) layer. Beneath of the BOX layer, high resistivity handle wafer made from floating zone method was ...

This paper describes a temporal filter aimed to the simultaneous cancellation of fixed pattern noise and temporal noise from image sequences by exploiting all the data provided by a typical image sensor (e.g. CCD/CMOS).

This paper presents a single-bit CMOS image sensor (CIS) that uses a data processing technique with an edge detection block for simple iris segmentation. In order to recognize the iris image, the image sensor conventionally captures high-resolution image data in digital code, extracts the iris data, and then compares it with a reference image through a recognition algorithm. However, in this ca...

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 an...

Digital images captured from CMOS image sensors suffer Gaussian noise and impulsive noise. To efficiently reduce the noise in Image Signal Processor (ISP), we analyze noise feature for imaging pipeline of ISP where noise reduction algorithm is performed. The Gaussian noise reduction and impulsive noise reduction method are proposed for proper ISP implementation in Bayer domain. The proposed met...

The CMOS (Complementary Metal-Oxide-Semiconductor) is a new type of solid image sensor device widely used in object tracking, object recognition, intelligent navigation fields, and so on. However, images captured by outdoor CMOS sensor devices are usually affected by suspended atmospheric particles (such as haze), causing a reduction in image contrast, color distortion problems, and so on. In v...
