Abstract: An anode substrate constituted of a conductive film forming substrate and a reinforcing substrate having different thermal expansion coefficient and being bonded together by the arrangement of adhesive layers is disclosed. The substrate can prevent creation of cracks on the conductive film forming substrate when heating and cooling the anode substrate. The adhesive layers are arranged at an interval, each of the adhesive layers being formed into a shape selected from a group consisting of a rectangular strip shape and a curved strip shape. The adhesive layers are arranged in a pattern to be symmetry with respect to a center line of the arrangement of the adhesive layers extending perpendicular to a line connecting both longitudinal ends of the arrangement of the adhesive layer. Furthermore, the adhesive layers include an outer adhesive portion located outward among remaining adhesive layers, and the outer adhesive layers are arranged shorter than the remaining adhesive layers.

Abstract: An optical printer head capable of increasing a level of a light amount for exposure emitted from luminous dot trains in view of an end cool phenomenon of filamentary cathodes and reducing loss of exposure energy. A light source includes luminous dot trains each constituted by a plurality of luminous dots each including an anode arranged on an anode substrate and a phosphor layer deposited on the anode, as well as filamentary cathodes arranged above the luminous dot trains so as to extend along the trains. A memory device is arranged so as to store therein correction information for ensuring uniform luminescence of the luminous dots. Light-amount correction is carried out on the luminous dots other than those positioned in proximity to each of both ends of the luminous dot trains excluded from light-amount correction, to thereby obtain correction information on the former luminous dots, which is then stored in the memory device.

Abstract: A digital photograph processing system capable of facilitating editing operation after photographing and outputting a photograph of defined dimensions in a short period of time. A cut range of picture data which permits a distance between two points of picture data required to be realized as an actual predetermined dimension is operated by merely inputting the two points by operation, resulting in a photograph being outputted. This highly facilitates designation of a cut position as compared with the conventional image or picture processing.

Abstract: A light-amount correction dynamic range expanding device that can increase the number of exposure gray levels without increasing the memory capacity of the storage section for light-amount correction. Input data is formed of (n+k) bits to increase exposure gray-scale level. A first look-up table stores the output densities to the number of exposure gray levels for photosensitive substances classified by photosensitivity. Of (n+k) bits output from the first table, a first selector selectively outputs only effective n bits to a second table 2 to use m bits needed for a photosensitive substance. The second look-up table stores brightness information to correct variations in brightness between luminous dots of a print head, with a memory capacity of n bits. A FIFO memory temporarily stores the brightness information. A selector 2 again converts the output from the FIFO memory into a (n+k)-bit form and ten it to a gray-scale control means.
