摘要： The objective of this invention is to perform high-precision tracking error detection and tracking control using digital circuitry at relatively low speed and with a small circuit scale. Tracking servo circuit is formed as a single-chip circuit. Low-pass filters (LPF) and gain control amplifiers (GCA) of the input portion are analog circuits, while the circuits after analog-digital (A/D) converters, that is, offset cancellation circuits, equalizers (EQ), first and second phase difference detectors, adder, low-pass filter (LPF), gain control amplifier (GCA), and servo DSP are all digital circuits.

摘要： A solid-state image pickup device and method are provided. The device can not only operate with a wide dynamic range but it also allows the user to switch the dynamic range corresponding to the photographic scene, and its operating method. Plural pixels, each of which has a photodiode, a transfer transistor, a floating diffusion region, an additional capacitance element, a capacitance coupling transistor, and a reset transistor, are integrated in an array on a semiconductor substrate. The capacitance of such floating diffusion region is less than that of such photodiode. A first signal S1 obtained by transferring part or all of the photoelectric charge accumulated in such photodiode PD to such floating diffusion region FD or a second signal S1+S2 obtained by transferring all of the photoelectric charge accumulated in such photodiodes to the potential obtained by coupling such floating diffusion region and such additional capacitance element CS is output to all of the pixels.

摘要： This invention is a solid-state image pickup device that solves the problem of limited dynamic range in the high luminance region in an image sensor having white pixels. White pixels or yellow pixels and at least red pixels, green pixels or blue pixels are arranged in array form on the light receiving surface of a semiconductor substrate. White pixels or yellow pixels have an additional capacitance CS connected to the photodiode via the floating diffusion, a capacitance coupling transistor S that can couple or separate the floating diffusion and the additional capacitance. The proportion of white or yellow pixels to the total number of pixels is higher in a central portion of the light receiving surface than a peripheral portion. The white or yellow pixel may share a floating diffusion with a red, green or blue pixel.
