摘要： 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.

摘要： An encoder is provided as one capable of accurately detecting an absolute value of an operating angle or the like of a scale plate in a simple configuration.In this encoder, each of light relay portions 4 formed along an operational direction α in the scale plate has a pattern of a one-dimensional array of some of optically transparent potions 5 and optically nontransparent portions 6 different from those of the other light relay portions. This allows the encoder to identify the light relay portion 4 located on a light receiving region 100, based on second light intensity profile data VY(m), using the patterns as codes. In the identification of the light relay portion 4, the light relay portion 4 can be accurately identified with respect to a position of a reference light propagation portion 7 formed for each light relay portion 4 in the scale plate. Furthermore, the encoder is able to calculate a center-of-gravity position of the identified light relay portion 4 relative to a reference position in the light receiving region 100, based on first light intensity profile data VX(n), and to calculate an operating angle of the scale plate from the center-of-gravity position.

摘要： The present invention relates to a photo-detecting apparatus having a structure for enabling photodetection with high sensitivity and wide dynamic range. When light is incident on a pixel section of an active pixel-type within a photo-detecting section, a voltage value corresponding to the amount of an electric charge generated at a photodiode included in the pixel section is outputted from the pixel section by way of a selecting transistor. A first pixel data readout section outputs the output from the pixel section as a first voltage value. On the other hand, the electric charge generated at the photodiode including the pixel section is outputted from the pixel section by way of a discharging transistor. The electric charge flown in a second pixel data readout section via a switch is accumulated in a capacitive element, and a voltage value corresponding to the amount of the accumulated electric charge is outputted from the second pixel data readout section as a second voltage value. The capacitance value of the capacitive element within the second pixel data readout section is greater than that of the parasitic capacitance section included in the pixel section.

摘要： A signal processing circuit 20 has switches 21, a shift register 22, and an integrating circuit 23, and outputs voltages Vout indicating luminance profiles in a second direction and in a first direction of light incident to a photosensitive region 10. The switches 21 are provided corresponding to groups of photosensitive portions on one side electrically connected among a plurality of pixels arrayed in the first direction and corresponding to groups of photosensitive portions on another side electrically connected among a plurality of pixels arrayed in the second direction. The shift register 22 is an element for sequentially reading electric currents from the groups of photosensitive portions on one side in the second direction and for sequentially reading electric currents from the groups of photosensitive portions on another side in the first direction. The integrating circuit 23 sequentially imports the electric currents from the groups of photosensitive portions on one side and the groups of photosensitive portions on another side sequentially read by the shift register 22, and converts the electric currents into voltages.

摘要： There is provided a solid-state imaging device in which images can be read at high speed. Since an n-th processing circuit (e.g. PU1) can be connected to n-th pixel columns (N1) in respective imaging blocks B1, B2, and B3 via switches Q (1), Q (4), and Q (7), signals from the adjacent pixel columns (N2) are to be processed separately by another processing circuit (PU2) even when a partial readout area R may be small. In addition, an image data arithmetic section 10 specifies the partial readout area R restrictively, which allows for higher speed imaging.
