摘要： A method and apparatus for producing index prints makes the trend of compensation for main prints coincide with the trend of compensation for the index prints. When a scanner determines an exposure compensation amount for each frame based on image data of each frame of a negative film, the information representing the exposure compensation amount for each frame is transmitted to the drive controllers via a controller. In a main print section, an exposure process is performed by the drive controller based on the information regrading the exposure compensation amount for each frame, thereby obtaining a main print. In an index print section, an exposure process is performed by the drive controller based on the same information regrading the exposure compensation amount for each frame, thereby obtaining an index print. Also, a density adjusting method easily and automatically adjust unevenness in density produced in an image printing stage. In a test mode, an image (gray image) with a uniform intermediate gradation is printed on a printing paper. A pixel having the maximum density is selected. Differences in density between the pixel having the maximum density and other pixels are calculated, and the gradations of the respective pixels are shifted based on the differences. Thus shifted gradations are registered as standards for the respective pixels.

摘要： A method and an apparatus for printing images on different mediums, such as images recorded on a photographic film and index print images onto photographic paper while an image printing device is reduced in size. A film carrier is positioned to a first position so that images recorded on a negative film set on the film carrier are exposed by a light source. Further, the film carrier is moved to a second position so that images formed on a liquid crystal panel are exposed by the same light source as that used for the exposure of the images on the negative film.

摘要： An image frame selecting apparatus for a photographic printer which is adapted to designate an image frame to be printed among image frames of a short photographic film. The apparatus includes operating devices the number of which is identical with that of the image frames of the short photographic film photographed and which are arranged in correspondence with the image frames of the short photographic film, the operating devices being adapted to select an image frame to be printed; an image frame designating device for designating the image frame corresponding to an operating portion of an associated one of the operating devices; a conveying device for conveying the short photographic film; and a controlling device for controlling the conveying device in such a manner that the image frame designated by the image frame designating device is positioned to a printing position. This arrangement allows the operator to select an image frame to be printed while collating the position of the selected image frame by means of the operating portion, thereby improving the operating efficiency in selection.
