ABSTRACT:
In photographic printing systems, it is necessary to detect image information of an original film to determine printing exposure amount for optimum prints. When an image sensor is used as a detector or for detecting image information, the detection area in the image sensor should correspond exactly with the detected area on the film. Particularly, when images are measured by separation into three colors of RGB (Red, Green, Blue), color registration among RGB should be attained. Image information can be automatically and accurately detected and processed without needing mechanical positional adjustment of the image sensor(s).
