ABSTRACT:
The present invention includes a film or video image pickup signal recording/reproduction system having an image pickup apparatus outputting an image pickup signal, a recording apparatus recording the image pickup signal, a reproduction apparatus reproducing the recorded signal, a characteristic conversion apparatus switching the characteristic of the reproduced signal, and a display apparatus displaying the signal output from the characteristic conversion apparatus. The image pickup apparatus has two kinds of gamma curve characteristics. The gamma curve characteristic data is recorded by the recording apparatus and extracted by the reproduction apparatus. The gamma curve characteristic of a reproduction image is switched by the characteristic conversion apparatus depending on the data. The image is output on a display apparatus.
