20080253616 | Imaging System and Imaging Method - The present invention relates to, for example, an image pickup system having a structure capable of imaging a subject at a low power consumption and a low cost even when the subject may be dark. The image pickup system comprises an image pickup device, a peak position detecting section, a partial image acquiring section, and a partial image operating section. The image pickup device outputs image data that represents the two-dimensional intensity distribution of light incident on a photodetecting section, and outputs light intensity profile data that represents the one-dimensional intensity distribution of the incident light in each of first and second directions in the photodetecting section. The peak position detecting section detects a light intensity peak position in the two-dimensional intensity distribution of the light incident on the photodetecting section in the image pickup device, based on the light intensity profile data outputted from the image pickup device. The partial image acquiring section acquires a partial image from an entire image that can be imaged by the image pickup device so that the light intensity peak position detected by the peak position detecting section is made a specific position for the partial image in the entire image. The partial image operating section integrates the acquired partial image. | 10-16-2008 |

20120018621 | SIGNAL PROCESSING DEVICE AND PHOTODETECTION DEVICE - In a signal processing device of an embodiment, an integration circuit accumulates a charge from a photodiode in an integrating capacitor element, and outputs a voltage value according to the amount of charge. A comparator circuit, when the voltage value from the integration circuit has reached a reference value, outputs a saturation signal. A charge injection circuit, in response to the saturation signal, injects an opposite polarity of charge into the integrating capacitor element. A counter circuit performs counting based on the saturation signal. A holding circuit holds the voltage value from the integration circuit. An amplifier circuit outputs a voltage value that is K times (where K>1) larger than the voltage value held by the holding circuit. An A/D converter circuit sets a voltage value that is K times larger than the reference value as the maximum input voltage value, that is, a full-scale value, and outputs a digital value corresponding to the voltage value from the amplifier circuit. | 01-26-2012 |
