Abstract: To reduce complication of a configuration of a vehicle while suppressing an increase in weight of the vehicle, a camera system mounted on a vehicle includes an imaging unit to capture multiple frame images of an outside of the vehicle per cycle and an image processor to obtain the multiple frame images from the imaging unit and separate the multiple frame images into a first given number of frame images as a recognition target and a second given number of frame images as a storage target to be stored in an image recorder. The image processor separately outputs the first and second given numbers of frame images to be recognized and stored, respectively.

Abstract: In an image generating apparatus, an image combining unit combines, for each of first and second processes in sequence, first and second images to generate a composite image having a digital pixel value representing a luminance level of the corresponding pixel by a first bit width. A range setter sets, for each of the first and second processes, a target luminance-level distribution range of at least one target with respect to the composite image; the distribution range represents a range within which luminance levels of the at least one target are distributed. A dynamic range adjuster adjusts a dynamic range of the composite image generated for one of the first and second processes such that the dynamic range of the composite image generated for the corresponding one of the first and second processes matches with the target luminance-level distribution range set for the first process.

Abstract: An image sensor includes a plurality of optical filters, a plurality of transmissive members, an imaging section, and a signal processing section. The optical filters transmit visible rays having a wavelength enabling visual recognition of a primary color, and the transmissive members transmit infrared rays. A plurality of imaging elements of the imaging section are constituted by a plurality of groups. Each of the imaging elements includes optical filters or transmissive members. The signal processing section determines the luminance of each pixel of a produced image, based on measurement values measured by the imaging elements of a group corresponding to the pixel. At least one imaging element of each group is provided with a transmissive member, and the remaining one or more imaging elements are provided with the optical filters having no color or a primary color allocated to the group.

Abstract: An imaging system to be mounted in a vehicle is provided. The imaging system includes an optical wide-angle camera acquiring an image, and an object identifying apparatus. This object identifying apparatus executes a distortion correcting process with the acquired image and apply previously-prepared reference patterns to the image which has been subjected to the distortion correcting process such that objects in the acquired image are recognized.

Abstract: A device for controlling exposure of a camera is provided. An image of an area ahead of a vehicle is acquired by a camera provided in the vehicle. A traveling speed of the vehicle is acquired. An exposure area in the acquired image is set by a setting section, in which the exposure area is used for exposure control of the camera. By a calculating section, a control value for performing the exposure control is calculated based on pixel values of pixels included in the exposure area. The setting section changes a size of the exposure area based on the traveling speed, such that, when the traveling speed is a first speed, the size of the exposure area in the acquired image is smaller compared to that when the traveling speed is a second speed that is lower than the first speed.
