  • Patent number: 11700465
    Abstract: In a solid-state imaging element equipped with per-column ADCs, noise is reduced. A test signal source generates a test signal of a predetermined level. An analog-to-digital converter increases/decreases an analog signal according to an analog gain selected from among a plurality of analog gains, and converts the increased/decreased analog signal to a digital signal. An input switching section inputs, as the analog signal, either a test signal or a pixel signal to the analog-to-digital converter. A correction value calculation section obtains, on the basis of the test signal and the digital signal, a correction value for correcting an error in the selected analog gain, and outputs the correction value. A correction section corrects the digital signal according to the outputted correction value.

  • Publication number: 20230104085
    Abstract: The range-finding apparatus (1) includes a light source (200), an optical receiver (1103), a setting unit (100), a detector (1100), and a calculation unit (300). The light source (200) projects light with a first irradiation pattern in a first period and projects light with a second irradiation pattern in a second period. The optical receiver (1103) receives light to output a pixel signal. The setting unit (100) sets a reference signal on the basis of the pixel signal in the first period. The detector (1100) detects whether or not the pixel signal varies from the reference signal by a first value or more in the second period and outputs a first detection signal indicative of a result obtained by the detection. The calculation unit (300) calculates a distance to a to-be-measured object using the first detection signal.

  • Patent number: 9407428
    Abstract: Provided is a reception apparatus including: a correction unit that corrects phase compensation for each one of multiple phase-compensated segments that are connected one after another, in which the correction unit includes a timing generation unit that, based on a phase of a known signal, generates a timing at which an amount of the phase compensation is initialized, an amount-of-correction generation unit that, based on the phase of the known signal, generates an amount of correction for correcting the amount of the phase compensation, and a phase correction unit that performs phase correction on the phase compensation using the amount of the correction that is generated by the amount-of-correction generation unit.
