  • Patent number: 9237285
    Abstract: A solid-state image pickup device including a pixel section arranged with multiple pixel circuits in matrix having functions for converting an optical signal to an electrical signal and for accumulating the electrical signal depending on an exposure time, and a pixel driving section capable of driving through a control line to reset, accumulate, transfer, and output signal electric charge of the pixel section. The pixel section may have a pixel shared structure arranged with one selection control line, one reset control line, and multiple transfer control lines, including a readout-pixel section and an unread-pixel section in its entirety. The pixel driving section includes a pixel control section where an unread-pixel is normally fixed in a reset state. When reading a readout-pixel in a shared relationship, if its address is selected or a selection signal becomes active, the unread-pixel reset-state is cancelled to turn into an unread state.

  • Patent number: 9204070
    Abstract: An integrating A/D converter includes: a comparator comparing an input voltage to a reference voltage having a ramp waveform, a voltage value of which linearly varies with time; a higher-order bit counter starting operation or stopping operation triggered by inversion of an output signal of the comparator and outputting higher order bits by performing counting in a cycle of a clock signal; and a time-to-digital converter latching phase information of the clock signal corresponding to plural signals obtained by delaying an output signal of the comparator and decoding the latched values to output lower order bits having higher resolution than the clock cycle.

  • Patent number: 9113102
    Abstract: Disclosed is a method of acquiring physical information that acquires physical information by using a semiconductor device. The semiconductor device includes unit elements, each of which has a detecting unit and a unit signal generating unit. The method includes the steps of: providing an operation current supply unit supplying an operation current such that the unit signal generating unit outputs a unit signal, and a signal processing unit receiving the unit signal output from each of the unit elements forming the semiconductor device and outputting an output unit signal; and when a selective read mode is designated for reading the unit signal from a portion of the respective unit elements, an operation current of the output signal line of the unit signal generating unit not to be read is reduced so as to be smaller than an operation current of the output signal line of the unit signal generating unit to be read.

  • Patent number: 8748793
    Abstract: An image pickup element includes a light-receiving portion having a matrix arrangement formed by disposing first-direction arrays, each having photoelectric conversion portions arranged in a first direction with a predetermined gap maintained therebetween, in a second direction orthogonal to the first direction, and micro-lenses provided above the light-receiving portion. A certain first-direction array in the matrix arrangement is provided with a pair of photoelectric conversion portions that optically receive, via a pair of micro-lenses, photographic-subject light beams passing through a pair of segmental regions in an exit pupil of a photographic optical system, the pair of segmental regions being disposed biasedly in opposite directions from each other in the first direction. The pair of micro-lenses is disposed such that light axes thereof extend through vicinities of edges of the pair of photoelectric conversion portions, the edges being the farthest edges from each other in the first direction.

  • Patent number: 8743253
    Abstract: To reduce random noise caused by address setting in an apparatus that controls a read address of an image sensing device, without causing a significant increase in circuit complexity. A ring shift register sets a low-order address value depending on a value in steps of which an overall address value is incremented, and a Gray code counter sets a high-order address value. In the ring shift register, a carry from the lowest-order bit to the highest-order bit does not occur, and thus use of the ring shift register makes it possible to reduce the maximum number of toggled bits. The Gray code counter does not need to include a complicated circuit for switching the value in steps of which to increment the high-order address value.
