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

An image display method for a rearview camera for displaying an image shot by a rearview camera mounted on a vehicle on a screen that can be viewed from a driver's seat, the method includes the step of displaying an auxiliary line image indicating the straight rear direction of the vehicle superimposed on the image shot by the vehicle on the screen. When the vehicle has approached the trailer within a predetermined range, an image from the rearview camera is converted to an image from a virtual overhead viewpoint then displayed on the screen. The driver easily back the vehicle to bring the hitch in the blind spot at the rear of the vehicle to coincide with a coupling member on the trailer while watching the screen display.

Image display method and apparatus for rearview system

A television camera equipped with a continuously-variable-speed electronic shutter function which can control the charge-storing time of a solid-state image sensor and an amplifier so that a video signal follows the optimum light amount for a subject at high speed and with high accuracy. A shutter-equipped image sensor which is controlled by a shutter pulse generating unit, converts light incident on an optical lens into an electric signal. The electric signal, after being passed through an amplifier and a signal processing unit, is detected by a video level detecting unit as a video level. A shutter control unit holds the shutter amount corresponding to the video level for each field to immediately calculate an estimated shutter amount by using a predetermined equation, and supplies the calculated shutter amount to the shutter pulse generating unit for each field. A control mode decision unit exclusively controls a gain control unit serving as an AGC and the shutter control unit.

A video camera specifies as a photometric area any block of a field of image to be picked up and picks up a subject to be seen by optimizing the amount of light regardless of the position where a television camera is located. The video camera comprises a solid-state image pick-up element (CCD), a display device and devices for controlling the diaphragm of a lens. In operation, the image picked up by the solid-state image pick-up element is divided into plural blocks to be displayed. Any block of these plural blocks can be specified as a photometric area. The amount of light for the photometric area is calculated and the diaphragm of the lens is controlled so that the subject can be seen by optimizing amount of light.
