ABSTRACT:
A color slide printing method produces image signals representing a positive image of a color slide using a color TV camera, converts the positive image signals into negative image signals for each of three colors using a contrast transfer circuit, sequentially displays the negative image signals for the three colors as black-and-white negative images in a brightness pattern on a black-and-white CRT while respectively inserting red, green and blue filters, each independently of the other two, in the printing optical path. The filtered black-and-white negative images expose color photographic paper. The positive image signals are sent to a color monitor to display thereon a positive color image of the color slide for visual inspection. When the positive color image on the color monitor is fuzzy or out of focus, the slide is considered to be positioned front side back, and the color TV camera is readjusted to focus on the back side of the color slide and the image signals are electronically converted so as to display mirror images on the black-and-white CRT and the color monitor.
