ABSTRACT:
The invention is an exposure metering system particularly adapted for use with an electronic camera. The exposure meter is responsive to the electrical signals formed by the image capturing electronics of the camera. Using these electrical signals, a pseudocolored image is formed and displayed based on the exposure of individual image sub-areas. A full tonal original image may thus be modified to provide an image having zones each with one selectable tonal value. Each zone thus formed represents a range of tones appearing in the original image.
