  • Patent number: 10999520
    Abstract: The present technology relates to an image capture device, a method of image capture, a signal processing device, a method of signal processing, and a program capable of capturing reliably a blinking image capture target. A predetermined image capture timing of an image capture unit is controlled so that image capture is performed N times during an exposure time in which at least a part of a turn-on period in which an image capture target is on overlaps with an exposure time of image capture of at least one time at a timing of dividing a blinking cycle in which the image capture target to be captured by the image capture unit configured to perform image capture at the image capture timing blinks into N equal parts where N represents more than one. The present technology is applicable to, in one example, a camera unit or the like used to capture an image.

  • Patent number: 10791287
    Abstract: Provided is an imaging control apparatus, method, and a vehicle, capable of efficiently analyzing an image. Among a short accumulation signal and a long accumulation signal of a photographed image, the short accumulation signal of a preceding frame is set to correspond to the short accumulation signal of a succeeding frame. The signal of the succeeding frame is processed by using the short accumulation signal of the preceding frame. The present technology is applicable to control imaging in an apparatus that supports driving of a vehicle by performing various processing, in each of frames of an N-frame sequence, for example, of recognizing various target objects necessary in supporting the driving of the vehicle, such as an obstacle, a guidance object, and other target objects, for example.

  • Patent number: 9602749
    Abstract: There is provided an image sensor that includes a pixel array section, a column processing section, and a row control section. The pixel array section is configured to include two or more shared pixel cells arranged in a two-dimensional array, the shared pixel cells each including a plurality of pixels that output electric signals by photoelectric conversion. The column processing section is configured to process the electric signals that are read at the same time from the shared pixel cells on a plurality of rows in the two-dimensional array. The row control section is configured to perform access control differently between one and another of the rows for reading the electric signals from the pixels in the shared pixel cells.

  • Publication number: 20060129703
    Abstract: Embodiments of the invention realize a power-save mode which prevents reduction in performance of a data storage device. The HDD as an embodiment of the present invention, upon receiving a request for switching to a power-save mode (PMREQ) from the host, judges whether the serial interface should be switched to the power-save mode based on the execution status of the command. When the HDD has determined not to switch the serial interface to the power-save mode, the HDD transmits a negative response (PMNACK) to the host and keep the serial interface in the active mode. By denying switching to a power-save mode when data transfer is executed within a short period of time, etc., it is possible to prevent reduction in performance of the data storage device.
