We developed a pixel-parallel image processing algorithm for detecting and tracking temporally modulated light signals for use as optical ID tags. The proposed algorithm requires no wavelength filters and obtains position information on signals at a high frame rate while decoding transmitted data. We implemented the proposed algorithm in a digital vision chip, a pixel-parallel processor embedde...
In this paper, spatiotemporally varying exposure imaging for high quality image reconstruction is introduced and a CMOS image sensor with a spatiotemporal exposure control function is presented. Moreover, we show the effectiveness of the spatiotemporally varying exposure imaging by reconstructing high quality image by simulation.
A submicron pixel's light and dark performance were studied by experiment and simulation. An advanced node technology incorporated with a stacked CMOS image sensor (CIS) is promising in that it may enhance performance. In this work, we demonstrated a low dark current of 3.2 e-/s at 60 °C, an ultra-low read noise of 0.90 e-·rms, a high full well capacity (FWC) of 4100 e-, and blooming of 0.5% in...
A high-speed non-destructive CMOS image sensor with bi-directional multiple charge transfer active pixel scheme is presented. The high-speed intermediate pictures are used in the motion vector estimation with adaptive iterative search. The sensor has an ability to cancel FPN of intermediate image. The proposed adaptive iterative search with high-speed non-destructive intermediate pictures reduc...
Abstract The CMOS image sensor having VIPS(Vertically Integrated Photodiode Structure) was fabricated for the first time. By adding the high energy(~3MeV) ion implantation to the conventional CIS(CMOS Image Sensor) process, it was verified that the deep photo diode was successfully formed under the normal photodiode on a pixel. And it was observed that this image sensor can detect the visual im...
Products from the Milbeaut Series for cellular phone cameras. These products integrate an image engine that processes high-resolution, high-speed, and small CMOS image sensor images beautifully and at high speed with low power consumption processes utilizing 90nm CMOS technology. We have developed highperformance M-4MO that is capable of processing up to 5 million pixels and MC-3 that can help ...
We have been developing polarization-analyzing CMOS image sensor with monolithically embedded polarizer [1, 2]. Differing from preceding works [3-5], we implement on-chip polarizers configured with a metal wiring layer available in standard CMOS technology. In the last workshop, we have demonstrated the polarization-analyzing functionality with a CMOS image sensor fabricated with 0.35 μm standa...
Active perception refers to a theoretical approach grounded on the idea that perception is an active process in which the actions performed by the agent play a constitutive role. In this paper we present two different scenarios in which we test active perception principles using an evolutionary robotics approach. In the first experiment, a robotic arm equipped with coarse-grained tactile sensor...
In this paper several tuning strategies for integrated active filters are discussed. Furthermore we compare two compensation schemes to decrease the temperature dependence of the transconductance value of a differential gain stage. The compensation circuitry consists of on-chip temperature sensors and a level adjustment circuit all realized by standard CMOS transistor techniques. The temperatur...
