| Research Abstract |
3-D image sensors have been studied and a real・time high-resolution 3-D image capturing system has been realized. Using CMOS APS pixels, an original time-domain ADC and a sub-pixel detection method, a high accuracy range measurement system has been demonstrated.. For objects at a distance of 1200mm the measurement error was within 0.1% at the range finding speed of 23.3 range map/sec. A correlation sensor has been also developed to realize-22.8dB SBR.
An intellectual visual feedback system has been studied, and an improved general-purpose 64x64 pixel vision chip has been implemented. Compared with the conventional analog chips, a high speed vision processing has been realized at a speed of several μsec. several tens μsec. Combining multiple PEs, a high speed visual feedback system has been demonstrated. A high resolution and high speed version was implemented for commercial use collaborating with a company. A variable focus lens has been also studied.
A system of variable space-sampling image sensors has been studied, and its functionality has been extended by multiple high-speed random access image sensors (SVS). In detail, An IBR system with a dense array of SVSs was developed for a real-time capturing of images from a virtual viewpoint, and a network sensor system with globally distributed SVSs has been demonstrated to selectively obtain moving objects to be transferred to a server via network. A variable threshold and capacitance sensors for a wide dynamic range operation is also studied for their possibilities.
