摘要： A white balance adjustment apparatus for adjusting red, green and blue video signals of an aiming subject has amplifiers for amplifying the R, G, B video signals, respectively, a brightness detector for detecting the brightness of the subject, and a mode selector for selecting either an outdoor lighting mode or an indoor lighting mode in accordance with the brightness detected by the brightness detector. A white detector is provided for receiving the R, G, B video signals for each pixel and detecting a pixel with R, G, B video signals that falls in a narrow white range when the outdoor lighting mode is selected, and in a wide white range when the indoor lighting mode is selected. An integrator integrates the number of detected pixels in the white range. A white balance gain control controls the gain of the amplifiers based on the integrated result of the integrator.

摘要： In an image pickup device, a signal mixer 7 mixes the image signals of different quantities of exposure outputted by an image sensor 4. A peak level detector 12 detects peak level of the mixed signal, and a peak level judge 13 decides whether the peak level is within a predetermined range or not. A controller 6 controls a ratio of the quantities of exposure for the image sensor 4 according to the decision by the peak level judge. Thus, the image pickup device has a good dynamic range in correspondence a dynamic range of an object, and an object image is reproduced well. Further, an iris device is also controlled appropriately when the dynamic range is controlled.
