Photographic printer having a CRT for illuminating an original with a flying spot to print an image of the original

摘要

A photographic printer having a CRT for illuminating an original with a flying spot to print an image of the original on a photographic material is provided with a digital filter for filtering video signals of the original in digital form to cancel the persistency effect of the CRT. An image signal processing device processes the video signals for color and gradation corrections, and a controlling device controls the CRT to cause the flying spot to have its luminance varied according to the image-processed video signals. The video signals after image processing are displayed on a monitor for visual inspection.
