CONFERENCE PROCEEDINGS FREE ACCESSCompound-eye cameras have large design capability of system configuration and functions that cannot be achieved by conventional single-eye camera. We propose high-frame-rate multispectral three-dimensional compound-eye camera TOMBO (Thin Observation Module by Bound Optics), and formulate its imaging property. A prototype TOMBO with complementary color filters is fabricated, and fundamental experiments of multispectral imaging is shown.View full abstractDownload PDF (823K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn this paper, we present the new row-parallel search and address encoding architecture, and circuit implementations for high speed 3-D range-fin ding using the light-section method. We propose the new integration tech nique for fast integration, the row-parallel embedded binary search tree and address encoding for high-speed detection and readout of activated pixel addresses, and a mask circuit for masking operation of a detected pixel. We achieve 14.3k range maps/s operation at a system clock of 180MHz and the maximum range error and the standard deviation of range error is 0.997mm and 0.258mm respectively at a target distance of 400mm.View full abstractDownload PDF (709K) -

CONFERENCE PROCEEDINGS FREE ACCESSThis paper presents a CMOS Image Sensor for car-to-car and road-to-car optical communications using LED signal light source. A prototype sensor with 320x480 image pixels and 320x480 communication pixels is implemented with 0.18μm CMOS technology. The measurement results of the implemented chip demonstrates for the first time that a spatial optical communication using a CMOS image sensor and a LED light successfully works in long distance of over 70meters and sufficient data rate of 10Mbps for sending video signals while attaining signal-light finding and tracking functions.View full abstractDownload PDF (959K) -

CONFERENCE PROCEEDINGS FREE ACCESSThis paper describes an improved two-stage charge transfer pixel for low-noise global shutter imaging and dual global shutter. In the proposed pixel, low noise level of 2.7e- and high shutter efficiency of 99.7% is attained by dual doping pinned diodes, shielding structure and stepwise potential. Proposed dual global shutter operation enables attractive functions such as wide dynamic range imaging, motion detection and dual consecutive snapshot imaging.View full abstractDownload PDF (1155K) -

CONFERENCE PROCEEDINGS FREE ACCESSThis article discusses column-parallel readout circuits design for high-speed imaging while attaining low-noise and wide dynamic range. The analysis of noise and response time of the column readout circuits including pixel source follower and column amplifiers shows that there is a trade-off between the attainable readout speed and noise. Column-parallel analog-to-digital converters (ADCs) are useful for achieving high-speed, low-noise and wide dynamic range imaging. Three major column ADCs are compared and their performances are discussed using figure of merits (FoMs) defined with several viewpoints of ADC performance. Column readout timing and digital correlated double sampling techniques are also discussed.View full abstractDownload PDF (1091K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe have developed a 1/2.3-inch 10.3Mpixel Back-Illuminated (BI) CMOS Image Sensor with 1.65x1.65μm^2 pixel. By using the FD boost-driving architecture, this sensor achieves a saturation signal of 9130e-, a conversion gain of 75μV/e- and a random noise of 1.7e-rms. Moreover, in employing BI process, this sensor achieves a sensitivity of 9890e-/lux・s and an F-number dependence of 0.99 (F2.8/F5.6).View full abstractDownload PDF (797K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe report a 2.2/3-inch 4K2K single CMOS image sensor based on a dual-resolution-and-exposure (DRE) technique. The motion information from the red and blue signals is used for spatio-temporal deconvolution of the green/red/blue signals to improve the sensitivity of image sensor by a factor of 4× in comparison to a conventional progressive scan.View full abstractDownload PDF (766K) -

CONFERENCE PROCEEDINGS FREE ACCESSSingle-chip color imaging is one of the practical method to realize a compact Super Hi-Vision (SHV) camera. We have developed an experimental pickup system with a 33-M-pixel color CMOS image sensor and measured its performance as the SHV image quality. The sensor has Bayer color filter array and the signal format is compatible with the conventional SHV camera which uses four 8M-pixel CMOS image sensors. The experiment results showed that the resolution is equivalent to or surpassing the conventional camera. Though there are still much room for improvement of its performance on the sensitivity, SNR and color reproduction characteristics, we confirmed the possibility of a practical compact SHV camera by the single chip color imaging.View full abstractDownload PDF (564K) -

CONFERENCE PROCEEDINGS FREE ACCESSA high data rate and a high resolution of a single-slope column-parallel A/D converter in the CMOS image sensor requires a fast system clock, and it causes large power consumption on the digital circuit region. This paper describes two low power circuits for the digital region of the single-slope column-parallel A/D converter. One is a latch circuit of a dynamic comparator for the gray-code counter data, and the other is a low power current sense amplifier using push-pull CMOS inverter. Simulation results show effectiveness for low power operation.View full abstractDownload PDF (593K) -

CONFERENCE PROCEEDINGS FREE ACCESSThe condition that super-resolution can exist is examined by looking over existing proposed systems. It is found that, in most cases, the aliasing which takes place in sampling where the sampling theorem is not satisfied is essential, and the image signals obtained by the solid-state image sensors satisfy this condition, while those by taking tubes do not.View full abstractDownload PDF (892K) -
