Abstract: A distance measurement device includes: an image capturer that captures N segmental images corresponding to N segmental distances into which a distance measurement range is divided; and a range image generator that generates a range image from the N segmental images. The range image generator determines: among segmental pixels included in the N segmental images, a segmental pixel having a maximum signal value from N segmental pixels at the same pixel position among pixel positions; a value indicating a segmental distance of the segmental pixel having the maximum signal value to be a distance value of the pixel position of the range image, when the maximum signal value is greater than or equal to a threshold; and a value indicating a value outside the distance measurement range to be the distance value of the pixel position of the range image, when the maximum signal value is less than the threshold.

Abstract: An imaging device includes a photoelectric converter generating signal charge; a charge storage region storing the signal charge; a first transistor having a gate coupled to the charge storage region; a second transistor having a source and a drain; and voltage supply circuity supplying voltages varying with time. An output of the first transistor is fed back to the second transistor and is supplied to the charge storage region. A reset operation for discharging the signal charge in the charge storage region includes a first reset operation and a second reset operation. In the first reset operation, the second transistor changes from an OFF state to an ON state and then changes to an OFF state. In the second reset operation, the voltage supply circuity supplies the voltages to a gate of the second transistor so that the second transistor gradually changes from an OFF state to an ON state.

Abstract: A solid state image sensor includes at least a plurality of pixel cells and a vertical scanning circuit. Each of the pixel cells includes an avalanche photodiode, a floating diffusion portion, a transfer transistor, a reset transistor, an amplifier transistor, a selection transistor, a count transistor, and a capacitor. The amplifier transistor outputs a voltage signal responsive to the amount of charge stored in the floating diffusion portion. The capacitor has terminals one of which is connected to the count transistor. The vertical scanning circuit is configured to be able to supply different levels of voltages to the other terminals of the capacitors.

Abstract: A distance measuring device includes a control unit and a measuring unit. The control unit controls a photodetector unit. The photodetector unit includes a photoelectric transducer element and an output unit. The photoelectric transducer element generates electrical charges on receiving light reflected from a target as a part of measuring light emitted from a light-emitting unit. The output unit outputs an electrical signal representing a quantity of the electrical charges generated by the photoelectric transducer element. The measuring unit calculates, in accordance with the electrical signal, a distance to the target within a measurable range. The control unit sets, in each of a plurality of intervals that form the measurable range, a conversion ratio of the quantity of the electrical charges generated by the photoelectric transducer element to a quantity of the light received by the photoelectric transducer element.

Abstract: An image recognition device includes: a luminance image generator and a distance image generator that generate a luminance image and a distance image, respectively, based on an image signal of an imaging target object output from a photoreceptor element; a target object recognition processor that extracts a target-object candidate from the luminance image using a machine learning database; and a three-dimensional object determination processor that uses the distance image to determine whether the extracted target-object candidate is a three-dimensional object. If it is determined that the target-object candidate is not a three-dimensional object, the target-object candidate extracted from the luminance image is prevented from being used, in the machine learning database, as image data for extracting a feature value of a target object.
