    • 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.
    • 用于制作索引图案的方法和装置使得主打印件的补偿趋势与索引打印的补偿趋势一致。 当扫描仪基于负片的每帧的图像数据确定每帧的曝光补偿量时,表示每帧的曝光补偿量的信息经由控制器发送到驱动控制器。 在主打印部分中,通过驱动控制器基于每个帧的曝光补偿量的信息重新进行曝光处理,从而获得主打印。 在索引打印部分中,通过驱动控制器基于相同的信息执行曝光处理,每个帧重新调整曝光补偿量,从而获得索引打印。 此外,密度调节方法容易且自动地调节在图像印刷阶段中产生的密度不均匀性。 在测试模式中,将打印纸上印刷具有均匀中间灰度的图像(灰度图像)。 选择具有最大密度的像素。 计算具有最大密度的像素与其他像素之间的密度差异,并且基于差异来移位各个像素的灰度。 这样移位的等级被注册为各像素的标准。

    • An apparatus for exposing index prints, in which a plurality of images recorded on a photographic film are displayed on an image display device and a photographic printing paper is exposed by light transmitted through the image display device so that an index print is prepared on the photographic printing paper such that the plurality of images are arranged in a matrix. The apparatus includes a system for setting the number of frames displayed on the image display device and exposure magnification of the images displayed on the image display device; dividing a plurality of image frames of the photographic film every predetermined number of frames to be displayed on the image display device; displaying, on the image display device, the plurality of image frames of the photographic film every predetermined number of the divided image frames; and exposing the divided plurality of image frames on the photographic printing paper at predetermined intervals in accordance with display of the image display device. Further, a photographic printer includes a film exposure section, an index exposure section, a conveying device, and a light-source controlling device for controlling an amount of light from the light source based on an operating condition of the index exposure section.
