Smart Image Capturing and Pre-processing

3-D image sensors have been studied and a real time high-resolution 3-D image capturing system has使用CMOS APS pixels， an original time-domain ADC and a sub-pixel检测方法，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 speedof 23.3 range map/sec. A correlation sensor has been also developed to realize-22.8dB SBR.Anintellectual视觉反馈系统has been studied，an improved general-purpose 64x64 pixel vision chip has been implemented. Compared with theconventional analog chipsa high speed vision processing has been realized at a speed of several μsec. several tens μsec.Combining multiple PEsa high speed visual feedback system has been demonstrated. a high resolution and high speed versionwas implemented for commercial use collaborating with a company. a variable focus lens has be alsoA system of variable space-sampling image sensors has been studied，其功能已扩展由多重高速随机存取图像传感器（SVS）. In者,An IBR system with a dense array of SVSs was developed for a real-time capturing of images from avirtual viewpoint,and a network sensor system with全球分布式SVSs has been demonstrated to selectivelyobtain moving objects to be transferred to a server via network. a variable threshold andcapacitance sensors for a wide dynamic range operation is also studied for their possibilities。
