ABSTRACT:
An apparatus for making a color print has a black-and-white CRT for frame-sequentially displaying black-and-white images of three monochromatic images of an image in the form of a brightness pattern thereon, color filters for sequentially changing the black-and-white images to corresponding monochromatic images, a printing lens for projecting each monochromatic image onto a photographic material, and means for changing image size by color through which each monochromatic image is projected on the photographic material by the printing lens, so as to make the three monochromatic images projected onto the photographic material the same size. In the case of the printing lens having a fixed focal length, the image size changing means comprises an amplifier for amplifying vertical and horizontal deflection signals for driving the CRT and means for changing a gain of the amplifier for every exposure of each monochromatic image, so as to make the three monochromatic images projected onto the photographic material the same size. On the other hand, in the case of the printing lens being variable in focal length, the image size changing means comprises memory means for storing magnifications by color for several specific focal lengths of the zoom printing lens and means for adjusting the focal length of the zoom printing lens according to the magnifications stored in the memory means, so as to make the three monochromatic images projected onto the photographic material the same size.
