Abstract: An image capturing system includes a photoelectric conversion unit, a charge holding unit, a multiple sampling information setting unit, a multiple sampling unit, a conversion unit, and an image reconstruction unit. The photoelectric conversion unit converts optical signals received by a plurality of pixels to electric signals. The charge holding unit stores the electric signals and holds the electric signals as charge signals. The multiple sampling information setting unit sets multiple sampling information used for a multiple sampling process. The multiple sampling information includes first multiple sampling information and second multiple sampling information. The multiple sampling unit performs the multiple sampling process using the multiple sampling information and the charge signals so as to output signals. The conversion unit converts the output signals to digital signals. The image reconstruction unit generates reconstructed images using the digital signals and the multiple sampling information, and outputs the reconstructed images.

Abstract: An object recognition apparatus includes a light source, an image sensor, a control circuit, and a signal processing circuit. The control circuit causes the light source to emit first light toward a scene and subsequently emit second light toward the scene, the first light having a first spatial distribution, the second light having a second spatial distribution. The control circuit causes the image sensor to detect first reflected light and second reflected light in the same exposure period, the first reflected light being caused by reflection of the first light from the scene, the second reflected light being caused by reflection of the second light from the scene. The signal processing circuit recognizes an object included in a scene based on photodetection data output from the image sensor, and based on an object recognition model pre-trained by a machine learning algorithm.

Abstract: An image generating apparatus generates an image to be displayed on a display and includes at least one memory and a control circuit. The control circuit acquires a plurality of camera images captured by a plurality of cameras installed in a vehicle, calculates a distance between one of the cameras and a target to be projected in in the camera images, detects a position of a light-transmissive object or a reflective object in the camera images, and generates an image from a point of view that is different from points of view of the plurality of camera images by using the plurality of camera images and the distance, the generated image including a predetermined image that is displayed at the position of the light-transmissive object or the reflective object.

Abstract: A crossing point detector includes memory and a crossing point detection unit that reads out a square image from a captured image in the memory, and detects a crossing point of two boundary lines in a checker pattern depicted in the square image. The crossing point detection unit decides multiple parameters of a function model treating two-dimensional image coordinates as variables, the parameters optimizing an evaluation value based on a difference between corresponding pixel values represented by the function model and the square image, respectively, and computes the position of a crossing point of two straight lines expressed by the decided multiple parameters to thereby detect the crossing point with subpixel precision. The function model uses a curved surface that is at least first-order differentiable to express pixel values at respective positions in a two-dimensional coordinate system at the boundary between black and white regions.

Abstract: An image capturing apparatus includes a first camera that captures a first image, a second camera that captures a second image, a lens cover that includes transparent parts and ridgelines and that covers the first camera and the second camera, and a processing circuit that identifies a pixel located in an area, in which it is necessary to interpolate a pixel value, in the first image, and generates an output image using the first image and interpolation pixel information for interpolating a pixel value of the identified pixel. Each ridgeline between adjacent parts of the lens cover is twisted with respect to a base line extending between a center of a first lens of the first camera and a center of a second lens of the second camera. An upper part of the lens cover opposes a base on which the first camera and the second camera are disposed.
