Abstract
An image-pickup display apparatus including a camera unit with: an image-pickup optical system; an image-pickup device having a light intercepting surface at a position of image formation by the image-pickup optical system, a signal processing circuit for generating a picture signal based on an image-pickup signal output by the image-pickup device, and a controller for correcting exposure by controlling the image-pickup device and the signal processing circuit. The display unit also includes: a liquid-crystal display unit having a liquid-crystal display panel and a back-light, a driver for driving and controlling the liquid-crystal display panel, a back-light controller for driving and controlling the back-light, and a picture processor for outputting a driving signal to the driver on the basis of the picture signal generated by the signal processing circuit employed in the camera unit, where receiving a drive/control signal output by the driver employed in the display unit as a feedback signal, the controller employed in the camera unit controls the image-pickup device and the signal processing circuit employed in the camera unit as well as the picture processor and the back-light controller employed in the display unit to put the drive/control signal in an optimum range.
