An illuminating device includes a detecting section configured to detect a vehicle height of a forward vehicle running in front of a vehicle; and a control section configured to control an illuminating range of a head lamp of the vehicle according to the vehicle height.

Illuminating device, illuminating method, program, and medium

A vehicle surroundings information output system includes a vehicle surroundings information obtaining mechanism obtaining information about the vehicle surroundings, an object detector detecting an object around the vehicle based on the obtained vehicle surroundings information, an outputting mechanism outputting information relating to the detected object, a detection reliability determining mechanism determining the detected detection reliability of the detected object, and a notifying information generator generating notifying information that relates to that object according to the detection reliability. The notifying information generator is structured to generate notify information that does not easily stimulate at least one of the five senses of a driver when the detection reliability of the object is low as compared to when that detection reliability is high.

Vehicle surroundings information output system and method for outputting vehicle surroundings information

An imaging device stores and photoelectric-converts incoming light from an object of which an image is to be captured with a CCD, and controls an output level of a picture signal obtained by signal processing an image signal output from the CCD. An output adjustment value of the picture signal in the output control is set to become 50 to 70 IRE according to a peak value of the picture signal when a test pattern is captured under standard conditions. Accordingly, it is possible to have a typical imaging device display a captured image darker, and thus enable imaging suitable for nighttime imaging and the like.

Imaging device and visual recognition support system employing imaging device

A form of the image pickup apparatus of the invention is characterized by including an image pickup portion that receives a incident light from an image-pickup object and performs a photoelectric conversion of the light, and an image processing portion that performs a spatial filter process of removing a predetermined low-frequency component from a picked-up image output by the image pickup portion.

Image pickup apparatus and image pickup method

A second circuit separately extracts a synchronization signal and brightness signal from an image signal output from a camera for capturing an image of a subject. A gamma amplifier produces a gamma correction signal based on a brightness ratio characteristic in which a display brightness increases as the signal level of the brightness signal increases and the display brightness is set using a display brightness correction ratio which is preferably 70 to 90% of an equi-proportional display brightness correction ratio when the signal level of the brightness signal falls in a high-brightness range. A liquid crystal display receives the gamma correction signal and displays an image captured by the camera with the display brightness set in accordance with the brightness ratio characteristic while synchronizing with a drive timing signal output from a first circuit. Thus, the difference in display brightness between different high-brightness regions or subjects is made large, whereby halation which may otherwise occur between those regions or subjects can be prevented.

Night vision system and control method thereof

A vehicle visibility assist device is started up when a switching operation of a switch for an external vehicle light is detected and when it is determined by a brightness sensor that it is darker outside of the vehicle than a predetermined threshold. The visibility assist device projects infrared light to a region outside the vehicle, captures a reflection of the light, processes an image of the region outside the vehicle, and projects the image onto a surface visible to the vehicle operator.

Vehicle visibility assist device and method

Liquid crystal display 1 has a surface disposed in parallel with a surface of holographic concave mirror 2. Liquid crystal display 1 causes a revolution about a display center 'd' of holographic concave mirror 2 in a back-and-forth direction as indicated by arrow .alpha.. In response to such revolution around holographic concave mirror 2, liquid crystal display 1 causes an autorotation about its vertical center 'e' in the back-and-forth direction as indicated by arrow .beta..

Head-up display apparatus

A display intensity control apparatus for controlling under dark ambient conditions the display intensity of an automobile display system comprises a plurality of display units (e.g., LED, FLT, Lamp) for providing displays effected by display elements of different types. Under dark ambient conditions, a pulse signal with a predetermined duty ratio is generated at a predetermined frequency and the display intensity of selected one of the display units is decreased in accordance with the duty ratio. Simultaneously, the duty ratio of the pulse signal is changed, and the display intensities of the other display units are decreased in accordance with the changed duty ratio.

Display intensity control apparatus

An electrical controlling device with a single actuating lever, which may be either twisted about its long axis to activate a first electrical controlling means, or tilted about at least one tilt axis perpendicular to its long axis in order to activate a second electrical controlling means.
