CMOS Image Sensors and the Quanta Image Sensor
2018 International Conference on Optical MEMS and Nanophotonics (OMN), 2018This paper briefly reviews CMOS image sensor invention and development. The focus of the paper is on a possible successor - the Quanta Image Sensor – a photon-counting image sensor that operates at room temperature without avalanche multiplication. Experimental results with 1Mpixel array devices are described.

Micro CMOS image sensor for multi-area imaging
2011 IEEE/IFIP 19th International Conference on VLSI and System-on-Chip, 2011We propose a micro complementary-metal-oxide semiconductor (CMOS) image sensor for simultaneous multi-area imaging. The sensor is designed for observation of mouse brain and its dimension is 550 µm × 850 µm. By connecting the sensors one after another, all the sensors are operated with only 5 lines.

A CMOS Image Sensor for Focal Plane Decomposition
2005 IEEE International Symposium on Circuits and Systems, 2005An alternative image decomposition method that exploits prediction via nearby pixels has been integrated on a CMOS sensor focal plane. The proposed focal plane decomposition is compared to the 2D discrete wavelet transform (DWT) decomposition commonly used in state of the art compression schemes such as EBCOT and SPIHT.

CMOS image sensor with programmable compressed sensing
2015 IEEE 11th International Conference on ASIC (ASICON), 2015The concept of compressed sensing CMOS image sensor is to compress data while sampling and prior to storage. This is our main idea to accomplish high speed imaging. In this paper, a CMOS image sensor with compressed sensing sampling mode is presented, which is composed of 256x256 pixel array.

Surveillance sensor systems using CMOS imagers
Proceedings 10th International Conference on Image Analysis and Processing, 1999Surveillance sensors are being applied in factory automation systems, traffic control, entrapment protection, automotive safety systems and in other applications where information about the occupancy of a scene is required. In order to detect object motion several methods exploiting distinct physical phenomena, e.g.

Integrated polarization-analyzing CMOS image sensor
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010A CMOS image sensor with an integrated wire grid polarizer to sense the polarization of light is presented. The chip consists of an array of 128 by 128 pixels, it occupies an area of 5×4 mm2 and it has been designed and fabricated in a CMOS 180nm process. Extinction ratio of 6.3 and 7.7 were achieved.

The evolution of CMOS image sensors
2013 IEEE Asian Solid-State Circuits Conference (A-SSCC), 2013Previous video cameras were big and heavy. However, CCD image sensors (CCD-ISs) replaced video camera tubes, so that video cameras became smaller and lighter, and video cameras as consumer products were introduced. Moreover, CCD-ISs created a market for digital still cameras and they replaced film cameras because of they were easy to use. However, CMOS
