摘要： A distance measuring device is to be connected to a wave transmitter and a wave receiver. The distance measuring device includes a distance measuring unit, which calculates a distance to the target based on a time interval between transmission of a measuring wave from a wave transmitter and reception of the measuring wave at a wave receiver. The target may be present across a preceding distance range and a succeeding distance range which are continuous with each other and both of which belong to a plurality of distance ranges defined by dividing a measurable distance range. In such a situation, the distance measuring unit calculates the distance to the target based on respective amounts of a preceding wave received at the wave receiver over a period corresponding to the preceding distance range and a succeeding wave received at the wave receiver over a period corresponding to the succeeding distance range.

摘要： A distance measuring device includes a controller and a distance calculator. The controller sets, in a first time period, a first measurement time range corresponding to a first measurement distance range; causes a light emitter to emit light and places a light receiver into an exposure state, in the first measurement time range; sets, in a second time period, a second measurement time range corresponding to a second measurement distance range; and causes the light emitter to emit light and places the light receiver into an exposure state, in the second measurement time range. At least one measurement condition is different between the first and second time periods. The distance calculator calculates the distance from the distance measuring device to a measurement target, based on the time from the emission to the reflection of light. The time is in at least one of the first and second time periods.

摘要： A plurality of pixels in a solid-state imaging device each include: a light receiving circuit that includes a light receiving element performing photoelectric conversion, sets, by an exposure signal, a photoelectric time for performing the photoelectric conversion, and outputs a light reception signal depending on whether or not incident light has reached the pixel within the photoelectric time; a counter circuit that counts, as a count value, the number of times the incident light has reached the pixel, based on the light reception signal; a comparison circuit that sets a value corresponding to the count value as a threshold, and sets a comparison signal to an on state in the case where the count value is greater than the threshold; and a storage circuit that stores, as a distance signal, a time signal when the comparison signal is in the on state.

摘要： An information processing system includes an object information generator and an output unit. The object information generator generates object information. A piece of the object information indicates a feature of an object present in a target distance section. The target distance section is one selected from a plurality of distance sections defined by dividing the distance measurable range in accordance with differences in elapsed times from a point of time when a light emitting unit emits a measuring light. The object information generator generates the piece of the object information based on a distance section signal associated with the target distance section. The output unit outputs the object information.

摘要： A solid-state imaging device includes: light-receiving elements; and first dispersive elements on a light-incident side of the light-receiving elements. Each first dispersive element includes first and second light transmissive film materials. The second light transmissive film material has a refractive index that is lower than that of the first light transmissive film material in a first wavelength range and higher than that of the first light transmissive film material in a second wavelength range longer in wavelength than the first wavelength range. A volume occupation ratio of the first light transmissive film material in each dispersive element increases from one end towards the other end of the dispersive element in a direction parallel to a light-receiving surface, while a volume occupation ratio of the second light transmissive film material in the dispersive element increases from the other end towards the one end in the direction.

摘要： 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.

摘要： 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.
