  • Patent number: 8200725
    Abstract: An arithmetic processing system processes a sensing signal and a first approximate offset signal to obtain a second approximate offset signal. The system includes a first arithmetic processor and a second arithmetic processor. The first arithmetic processor receives and processes the sensing signal and the first approximate offset signal to output a first arithmetic signal. The second arithmetic processor processes the first arithmetic signal to output a second arithmetic signal, and the second arithmetic signal is added with a predetermined offset signal to obtain the second approximate offset signal, and the second approximate offset signal is closer to a real offset signal of the sensing signal than the first approximate offset signal. A method of arithmetic processing is also disclosed.

  • Patent number: 8111291
    Abstract: Image capture systems capable of ensuring clear images are provided, in which an image capture module senses at least one image, and an operational module performs a compensation to the image capture system according to a modulation transfer function (MTF) value corresponding to the image, such that the image capture system can be operated under an optimized total gain thereby ensuring clear images.

  • Patent number: 7916176
    Abstract: A method of offset compensation for solid-state imaging devices is provided. In the method a first and second detection signal are obtained. The two signals are compared to obtain a difference value. A variable voltage is output according to the difference value to drive a magnetic element. The solid-state imaging device is moved by the magnetic element to compensate the offset of the solid-state imaging device. A system of offset compensation of the solid-state imaging device is also disclosed.

  • Publication number: 20090213230
    Abstract: An image capture method for capturing an image with a single lens is provided. The method includes: (a) sequentially moving an image capture unit to predetermined positions; (b) sequentially capturing a plurality of frames of images by the image capture unit at the predetermined positions, wherein at least one image distance difference exists among the images; and (c) generating at least one image file by a processing unit according to the images.
