Abstract: An image recognition apparatus includes a processing circuit and a control circuit. The processing circuit receives a first image obtained by performing multiple-exposure image capturing of a first subject. The processing circuit uses the first image to calculate a recognition accuracy of the first subject. The control circuit changes a condition of the multiple-exposure image capturing in a case where the recognition accuracy is lower than a recognition accuracy threshold.

Abstract: A camera system includes an imaging device that acquires a first image by a normal exposure including only one exposure and that acquires a second image by a multiple exposure including a plurality of exposures; and an image processor that extracts a feature value of a first object in the first image and that identifies one or more locations corresponding to the feature value in the second image.

Abstract: An imaging device including: a photoelectric converter including first and second electrodes and a photoelectric conversion layer therebetween; a voltage supplier; an output circuit for outputting a signal corresponding to the potential of the second electrode; and a detector for detecting the signal level. The change rate of the conversion efficiency of the photoelectric converter with respect to a bias voltage applied between the electrodes when the bias voltage is in a first range is greater than that when the bias voltage is in a second range higher than the first range. The voltage supplier, when the detected level is a first threshold or higher, causes the potential difference between the electrodes to be a first difference, and, when the detected level is lower than a second threshold that is the first threshold or lower, causes the potential difference to be a second difference greater than the first difference.

Abstract: An imaging device includes: unit pixel cells each including first and second electrodes, a photoelectric conversion layer therebetween, a charge accumulation region, and a signal detection circuit; and a voltage supply circuit, the voltage supply circuit supplying a first voltage to the second electrode in an exposure period. The start and end of the exposure period is common to the unit pixel cells. The photoelectric conversion layer has a photocurrent characteristic including first to third voltage ranges. In the third voltage range between the first and second voltage ranges, an absolute value of a rate of change of a current density relative to a bias voltage is less than in the first and second voltage ranges. The voltage supply circuit supplies a second voltage to the second electrode in a non-exposure period such that the bias voltage applied to the photoelectric conversion layer falls within the third voltage range.

Abstract: An imaging device includes a unit pixel cell. The unit pixel cell captures first data in a first exposure period and captures second data in a second exposure period different from the first exposure period, the first exposure period and the second exposure period being included in a frame period. A sensitivity per unit time of the unit pixel cell in the first exposure period is different from a sensitivity per unit time of the unit pixel cell in the second exposure period. The imaging device outputs multiple-exposure image data including at least the first data and the second data.
