ABSTRACT:
A digital electronic still camera operable in a text mode for clearly shooting a bilevel image, e.g., characters printed or formed on a document. A luminance signal can be roughly corrected with respect to shading by a simple circuit arrangement. This corrects a decrease in the quantity of light in the peripheral portion of a frame and thereby renders characters or similar bilevel images in a picture highly legible.
