Exposure apparatus for controlling the duration of exposure operations according to compensated exposure data |
摘要 |
The present invention provides an apparatus capable of controlling the duration of voltages applied to line exposure elements in proportion to the gray levels of a color to produce a gentle gradation of the color. This is achieved in the present invention by converting exposure data into compensated exposure data in which the duration of the exposure operation is compensated according to predetermined characteristics. The duration of the exposure operation of the exposure device is then controlled according to the compensated exposure data to thereby produce a smooth, high quality gradation of color.
