    • 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。

    • In a photographic material processing apparatus in which a photographic material is conveyed while being immersed and processed in photographic material processing liquids, guide members are provided at each boundary between adjacent processing tanks, and a cleansing liquid is supplied to the contact surfaces of guide members contacting where a photographic material comes into contact with the guide members to thereby rinse off the processing liquid adhering to the guide members. Accordingly, no degenerated matter of the processing liquid adheres to the guide members, the photographic material is not stained through contact with the guide members, and processing can be performed uniformly.
    • 在照相材料处理装置中,其中在照相材料处理液中浸渍和处理照相材料的同时,在相邻处理槽之间的每个边界处设置引导构件,并且将清洁液体供应到与导向构件接触的接触表面 其中照相材料与引导构件接触,从而冲洗附着在引导构件上的处理液。 因此,处理液的退化物质不粘附于引导构件,照相材料不会与引导构件接触而染色,并且可以均匀地进行处理。
