  • Patent number: 10230874
    Abstract: An imaging device includes: a control unit configured to control an output of an irradiation signal including an irradiation code used for control of a pattern of emission of irradiation light and an output of a reference signal including a reference code indicating a pattern used for detection of a correlation with reception light including reflection light of the irradiation light; and an imaging element configured to output a pixel signal indicating a correlation between the reception light and the reference signal, wherein one of the irradiation code and the reference code is a code in which weighted adding of a plurality of unit codes, in which a phase of a basic code having an impulse cross-correlation with the other code is shifted for a different shift amount, is performed.

  • Publication number: 20180149752
    Abstract: The present technology relates to an imaging apparatus and an imaging control method, which can change a distance measuring accuracy according to a distance from the imaging apparatus to an object. The imaging apparatus includes a control unit that controls outputs of an irradiation signal including an irradiation code and a reference signal including a reference code, and an imaging unit that includes a photoelectric conversion element, generates a pixel signal indicating correlation between reception light incident into the photoelectric conversion element and the reference signal, and generates a distance pixel signal based on a distance to an object on the basis of a ratio between a first pixel signal in a case where a first combination of the irradiation signal and the reference signal is used and a second pixel signal in a case where a second combination of the irradiation signal and the reference signal is used.

  • Publication number: 20170280042
    Abstract: [Object] To easily determine whether a flicker component is present. [Solution] An image sensor performs a process of generating image data by exposing a plurality of lines, each of which including a plurality of pixels, in sequence over a predetermined exposure time from exposure start timings that are different from each other whenever a predetermined period of a vertical synchronization signal elapses. A timing controller performs control for shifting each of the exposure start timings by a fixed time interval whenever the period elapses. A determination unit determines whether a component having luminance varying at a predetermined frequency along a direction perpendicular to the plurality of lines in the image data is present. A removal unit removes the component in the image data in a case where the component is determined to be present.

  • Publication number: 20170214890
    Abstract: An imaging device that includes a first color filter, a second color filer and an image sensor. The first color filter includes a first plurality of color filter regions that transmit a color of a first set of colors. The second color filter includes that transmit a color of a second set of colors. The second set of colors is different from the first set of colors. The image sensor detects light that passes through both the first color filter and the second color filter and generates an image signal.

  • Publication number: 20170214903
    Abstract: To improve the image quality in an imaging apparatus. A synchronization signal generator generates a synchronization signal indicating a synchronization timing for each of synchronization intervals. A synchronization interval controller changes, when an amount of change of the synchronization interval is input, the synchronization interval according to the amount of change. An imaging element generates image data by performing exposure within an exposure period between an exposure start timing when a start-setting time has elapsed from the synchronization timing and an exposure end timing when an end-setting time has elapsed from the synchronization timing after the exposure start timing. An exposure controller changes, when the amount of change is input, at least one of the start-setting time and the end-setting time on the basis of the amount of change.

  • Publication number: 20160316112
    Abstract: An image or a range image in a range at an arbitrary distance is acquired. An imaging device includes: a control unit configured to control an output of an irradiation signal including an irradiation code used for control of a pattern of emission of irradiation light and an output of a reference signal including a reference code indicating a pattern used for detection of a correlation with reception light including reflection light of the irradiation light; and an imaging element configured to output a pixel signal indicating a correlation between the reception light and the reference signal, wherein one of the irradiation code and the reference code is a code in which weighted adding of a plurality of unit codes, in which a phase of a basic code having an impulse cross-correlation with the other code is shifted for a different shift amount, is performed. The present technology can be applied, for example, to a camera that photographs a range image.
