ABSTRACT:
Adjustment of color density of a color picture to be recorded on a photosensitive material is performed in a color picture output device in such a manner that a test pattern print is outputted from the device and the density of the test pattern print is then compared with a standard pattern plate preliminarily prepared. After the actual output picture color density is measured by the standard pattern plate, the gain and offset for obtaining the standard density can be automatically calculated so as to thereby perform in smooth and high speed color picture outputting operation.
