A setup condition recorder for a color scanner for reproducing a reproduction picture, wherein an original picture to be reproduced, secured to a picture mount means, is scanned by a pickup head to obtain a picture signal, and wherein an operational unit determines setup conditions for the color scanner from the picture signal, and the setup conditions are recorded on a recording medium by a recording unit.

Setup condition recorder for a color scanner

A method for controlling exposure light beams for use in a picture reproducing machine such as a color scanner and a color facsimile, wherein a light beam is supplied to an acoustooptical deflector and is deflected thereby to obtain diffraction light beams which are incident to fixed light paths and are used for exposing a recording film, and wherein the diffraction light beams are controlled by varying a frequency of a supersonic wave supplied to the acoustooptical deflector so that each diffraction light beam may be or may not be incident to the respective light path.

A color control simulator for a picture reproducing machine such as a color scanner and a color facsimile, wherein an input means such as a pickup head scans an original picture to obtain color separation picture signals which index a memory table stored in a memory to output first color-corrected color separation picture signals, wherein the first color-corrected color separation picture signals of the table are replaced with second color-corrected color separation picture signals which are output by a color control means such as a color controller and a key board, and wherein a display means displays colors corresponding to the color-corrected color separation picture signals fed from the memory. A computer controls the input means, the memory, the color control means, and the display means.

Color control simulator for a picture reproducing machine

A method for automatically determining the color control conditions such as a highlight point, shadow point, a gradation control, color correction, and so forth, for a picture reproduction for use in a picture reproducing machine such as a color scanner and a color facsimile, wherein an original picture is scanned photoelectrically to pick up color separation picture signal data of the primary colors. The signal data is classified into groups to obtain a distribution condition, and according to the distribution condition obtained the color control conditions are determined.
