Abstract: Heat-blocking filter is a heat-blocking filter to be installed in a window glass of a vehicle. The heat-blocking filter substantially transmits visible light and infrared light in a first wavelength range, and substantially blocks infrared light outside the first wavelength range.

Abstract: A distance measurement device includes: a pulse light emitter that emits pulse light to a measurement target; an optical sensor that receives reflected light which is the pulse light reflected by the measurement target; and a controller that controls a light emission timing of the pulse light emitted by the pulse light emitter, and determines a distance to the measurement target, from a light reception timing of the reflected light detected by the optical sensor. The controller sets the light emission timing in each of N periods (N being a natural number less than K) selected randomly from continuous K periods (K being a natural number greater than or equal to 2) to a timing that is delayed by a random first time from a start time of the period.

Abstract: An image recognition device includes a light source that emits lighting pulses to a measurement space, a image generator that generates a distance image based on reflected light acquired by a light receiving element, a reflectivity calculator that calculates a correction coefficient corresponding to a reflectivity for each measurement section, and a lighting pulse controller that controls a number of lighting pulses emitted from the light source according to the correction coefficient for each measurement section.

Abstract: A distance measurement device includes: a light source configured to emit visible illumination light; an imaging element configured to receive reflected light of the illumination light from an object; and a signal processing circuit configured to reduce the emission of the illumination light in a predetermined period, detect a timing when the reception of the reflected light at the imaging element is reduced due to the reduction of the illumination light, and measure a distance to the object on the basis of the detected timing.

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.

Abstract: Each of column signal lines is connected to two or more of P pixels belonging to one of Q pixel columns of pixels. In each of the pixels, a first switch switches connection and disconnection between a light receiver and a first charge storage. A second switch switches connection and disconnection between the first charge storage and a second charge storage. A third switch switches connection and disconnection between the first charge storage and one of column signal lines corresponding to the pixel. The fourth switch switches the connection and disconnection between the second charge storage and the one of the column signal lines corresponding to the pixel.
