Abstract
A video printer is suitable to get hard copies of television images, and it has been making much progress in high quality technology with processing image data. We have made some investigations in getting high quality prints. First one is to reject the noise in reduced images, such as thumbnail prints. Another is the method of color comprehension with a television image and a print one.
It is well known to see the high-frequency noise in the thumbnail image without LPF. This LPF is set behind the frame memory and it requires a high dimension digital filter. It needs long time to process the data or much digital circuit. We have got a good thumbnail image with no noises using a mean filter.
There is any mismatch in color reproduction between television images and print images. For printers there needs a kind of color compensation because of color mismatch. We have made some investigations, such as the method for special use of print, non-linear compression from TV color space to printer color space and the method using TV signal processing.
