Provided is a vehicle headlight for forming a high-beam additional light distribution pattern overlaid on a high-beam light distribution pattern. The vehicle headlight is capable of making a driver feel the sense of turning-on of the headlight when the high-beam additional light distribution pattern is additionally formed. The vehicle lighting fixture can be configured to further form a turning-on perceptible light distribution pattern for causing a driver to feel a sense of turning-on together with the high-beam additional light distribution pattern.

Vehicle lighting fixture

A vehicle headlight system can include a headlight controller and a lamp unit incorporating a high beam module, which can emit favorable marking lights while the headlight controller associates each of a shading driver and a swivel structure with a shading width setter and a swivel setter, respectively. When a forward vehicle does not exist in a forward direction, the headlight systems can provide favorable light distribution patterns by overlapping the light distribution pattern projected from the high beam module with each of light distribution patterns for a high and low beam. When the forward vehicle exists, the headlight system can prevent the lamp unit from emitting a glare type light to the forward vehicle. Thus, the disclosed subject matter can provide vehicle headlight systems, which can emit favorable light patterns toward a pedestrian as a marking light, and which can provide favorable light distribution patterns to drive at night.

More accurate image evaluation is achieved by using information about faces contained in images. An information acquiring unit acquires, from an image containing at least one face, information about the size and the position of the at least one face.

In image processing on digital image signals, a color difference due to a type of image sensing device by which the image signals have been acquired is compensated. For this purpose, a characteristic value, such as an average of each digital image signal, is extracted from digital image signals of a plurality of subjects photographed by the same image sensing device. Based on the characteristic value, conversion of each image signal is carried out.

Image processing method to compensate for color differences due to a type of image sensing device

A digital still camera has a function to perform first and second exposures in a single imaging sequence. In the first exposure, imaging conditions are determined to obtain proper exposure amount of the background with available light. Then, the second exposure is carried out with the flashlight to illuminate the main subject. The photographic sensitivity, the shutter speed, and the aperture value for the second exposure are determined such that the exposure value in the second exposure is under-exposure by two steps or more, compared to that in the first exposure. Images obtained by first and second exposures are synthesized to obtain a composite image.
