  • Publication number: 20260237045
    Abstract: An object detection unit (120) detects a region in which a defect of an inspection target is inferred to appear, as a current defect region, by executing object detection on a current target image acquired by imaging the inspection target, and obtains accuracy of inference for the current defect region, as a current region confidence level. An inspection value calculation unit (140) calculates a current inspection value using an inspection coefficient used for calculating an inspection value and the current region confidence level. An anomaly detection unit (150) determines whether or not an anomaly has occurred in the inspection target based on the current inspection value.

  • Publication number: 20190189063
    Abstract: A light emission control apparatus includes: a transmittance determining unit that determines, based on image data, a temporal change in transmittance of a display unit of the display apparatus in a frame period; and a pulse determining unit that determines, based on a determination result by the transmittance determining unit, for each of partial periods in the frame period, a pulse width, a pulse amplitude, and a pulse position of a pulse supplied to a light-emitting unit of the display apparatus, wherein the pulse determining unit determines a pulse position for each partial period so that the pulse is set in a period where the transmittance in the partial period is relatively high, and determines, for a stable period, a pulse width and a pulse amplitude that are different from those of an unstable period.

  • Publication number: 20190139500
    Abstract: A display apparatus includes: a backlight module; a first panel transmitting a light from the backlight module based on a first image data; a second panel transmitting a light from the first panel based on a second image data; and at least one processor and/or at least one circuit to perform the operations of the following units: an acquiring unit configured to acquire an input image data; and a generating unit configured to generate the first image data and the second image data based on the input image data, wherein the generating unit generates the first image data and the second image data such that a decline in transmittance of the second panel due to an increase in a line-of-sight angle becomes larger than a decline in transmittance of the first panel due to the increase in the line-of-sight angle.
