ABSTRACT:
An image processing apparatus can rapidly produce a hard copy of a video image by setting parameters for processing an input image signal while a record medium is being advanced to an initial recording position. The parameters which are set are upper and lower limits for normalizing the input image signal, and are determined by performing histogram processing on the input image signal. In addition, the processing apparatus may include a plurality of combined normalization and gamma correction reference tables for processing the input image signal. One of the plurality of combined reference tables is selected on the basis of the upper and lower limits determined by the histogram processing of the input image signal. Alternatively, separate normalization and gamma correction reference tables may be used.
