摘要： In an imaging device, a difference calculation unit calculates a differential signal between charge signals that have been accumulated and are held by first and charge holding units with different timings. A multiple sampling unit performs multiple sampling processing on the differential signal, and an analog digital conversion unit converts a signal that has undergone multiple sampling processing to a digital signal. That is, multiple sampling processing is performed on a differential signal with a higher sparisty than that of an image signal.

摘要： 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.

摘要： 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.
