An image printer includes a first exposure mechanism for exposing a photosensitive material to an original image projected from a medium such as a negative film, and a second exposure mechanism for exposing the same photosensitive material to a pattern image which is to be printed on the photosensitive material external an area in which the original image is printed by the first exposure mechanism. Attribute information is detected from the medium and a corresponding pattern image is determined. Masking plates are provided to mask a part of the photosensitive material from a projected illumination of the first exposure mechanism. The masked portion of the photosensitive material is an area in which the pattern image is printed by the second exposure mechanism.

An optical transmitter having a higher diffusiveness and a higher transmittivity simultaneously is constructed so that a light from a lamp 2 of light source enters an optical fiber materials A and is transmitted to a reflector tube 1 of which mirror surface of the inner side is formed by vacuum deposition. The diffused light components in the reflector tube 1 are reflected on the mirror surface and directed towards an optical fiber materials B and transferred to an exposure device 3 having a PLZT shutter.

An exposure apparatus capable of color exposure operation and monochrome exposure operation. When a color exposure operation request is made, at least one of a red, blue, or green filter is positioned in a light path to produce exposure light having a predetermined wavelength. When a monochrome operation request is made, the color filters are retracted so as to allow white exposure light to pass.

An intensity of light emitted from a lamp is passed through a mirror tunnel and is directed to a disk which comprises three, B, G, and R, color filters, each extending 120 degrees on the disk. Each of the B, G, and R modes of light, separated on the disk, is guided through the optical fiber bundle and is transmitted to the PLZT elements. A pattern of the PLZT elements, determined by a group of dots of exposure data to be printed, are energized by a given voltage in synchronization with the rotation of the disk 13, thus allowing a desired mode or wavelength of light to pass selectively and fall efficiently on the printing paper.

An exposure apparatus has a color shifter disk which comprises blue, green and red color filters, formed by dividing the disk into three sectors, and a light shielding member arranged for moving into and out from the light path in synchronization with the rotating movement of the color shifter disk. The light shielding member advances into the light path to interrupt the exposure light when a boundary between two adjacent color filters of the color shifter disk moves into the light path, and retracts from the light path to pass the exposure light when the boundary between two adjacent color filters of the color shifter disk departs from the light path.

The present invention provides an apparatus capable of controlling the duration of voltages applied to line exposure elements in proportion to the gray levels of a color to produce a gentle gradation of the color. This is achieved in the present invention by converting exposure data into compensated exposure data in which the duration of the exposure operation is compensated according to predetermined characteristics. The duration of the exposure operation of the exposure device is then controlled according to the compensated exposure data to thereby produce a smooth, high quality gradation of color.

When printing images as ordinary prints on a photosensitive material, index prints are also automatically printed of a same size as the ordinary prints for higher work efficiency. At a projection exposure stage, exposure of a film is effected to obtain ordinary prints using a light source, a lens and a shutter. Also, data of images on the film is read by an optical reader and converted into digital signals. Index prints are then exposed by a PLZT print head which is controlled based on the digital signals.
