摘要： A method for removing background signal values from readout signal values generated by image pixels in a pixel array may include generating background signal values using optically black pixels formed around a border of the pixel array. The background signal values may be separated into blocks. Block average values may be calculated based on the background signal values included in each of the blocks. Corner regions of the pixel array may be free of image pixels and optically black pixels. Corner background signal values may be extrapolated based on the block average values. Image pixel background signal values may be interpolated based on the block average values and the corner background signal values. The image pixel background signal values may be subtracted from the readout values.

摘要： A pixel within a pixel array of an integrated-circuit image sensor outputs an analog signal representative of accumulated photocharge. First and second analog-to-digital conversions of the analog signal are initiated while the pixel is outputting the analog signal, the first analog-to-digital conversion corresponding to a low-light range of photocharge accumulation within the pixel and the second analog-to-digital conversion corresponding to a brighter-light range of photocharge accumulation within the pixel.

摘要： A CMOS sensor has unit pixels each structured by a light receiving element and three transistors, to prevent against the phenomenon of saturation shading and the reduction of dynamic range. The transition time (fall time), in switching off the voltage on a drain line shared in all pixels, is given longer than the transition time in turning of any of the reset line and the transfer line. For this reason, the transistor constituting a DRN drive buffer is made proper in its W/L ratio. Meanwhile, a control resistance or current source is inserted on a line to the GND, to make proper the operation current during driving. This reduces saturation shading amount. By making a reset transistor in a depression type, the leak current to a floating diffusion is suppressed to broaden the dynamic range.

摘要： An image sensor includes a light-electron conversion unit, a signal generation unit, and a selection unit. The light-electron conversion unit generates photo-charges from incident light. The signal generation unit accumulates photo-charges from the converter in a storage node during a detection period, and then generates a first analog signal and a second analog signal during an output period. The analog signals are generated based on an amount of photo-charges accumulated in the storage node. The selection unit generates an image signal based on one of the first analog signal and the second analog signal.
