    • In an image forming apparatus provided with an exposing section and a conveyor for conveying a plurality of light sensitive materials relative to the exposing section, the plurality of light sensitive materials are arranged in parallel in the conveying direction so that the exposing section is divided into plural exposing blocks corresponding to the plurality of light sensitive materials. There are provided a memory to memorize plural correction amounts each set based on a characteristic of one of the plurality of light sensitive materials, wherein the plural correction amounts are correlated with the plural exposing blocks in accordance with the corresponding light sensitive material; and a correcting section to correct the amount of light for each exposing block on the basis of the corresponding correction amount.
    • 在设置有暴露部分的图像形成装置和用于相对于曝光部分传送多个感光材料的传送器的情况下,多个感光材料沿传送方向平行布置,使得曝光部分被分成多个 露出对应于多个光敏材料的块。 提供了一种存储器,用于根据多种感光材料之一的特性来存储每组设置的多个校正量,其中多个校正量根据相应的感光材料与多个曝光块相关; 以及校正部,其基于相应的校正量来校正每个曝光块的光量。

    • The invention provides an apparatus for printing an image of a negative film on a photographic print paper. The apparatus is equipped with a zoom lens for changing a printing magnification rate and the zoom lens incorporates an adjustable diaphragm for changing an aperture size. A standard F-number for each of possible magnification rates is predetermined in view of actual printing result, and a resultant F-number is stored in a memory for each of possible magnification rates. In the apparatus provided a sensor, disposed on the optical axis of the zoom lens, for detecting the illuminance of a projected surface on the photographic print paper and CPU for controlling the adjustable diaphragm in response to the detected illuminance to determine an optimum aperture size to obtain the predetermined F-number for each of possible magnification rates. The optimum aperture size is stored in the memory for each of possible magnification rates.
    • 本发明提供一种用于在照片打印纸上打印负片的图像的装置。 该装置配备有用于改变打印放大率的变焦透镜,并且变焦镜头包括用于改变光圈尺寸的可调节光圈。 考虑到实际的打印结果,预先确定每个可能的放大率的标准F数,并且将所得到的F数存储在每个可能的放大率的存储器中。 在设置有设置在变焦透镜的光轴上的传感器的设备中,用于检测照相打印纸上的投影表面的照度和CPU,以响应于检测到的照度来控制可调节光阑,以确定最佳的孔径尺寸 为每个可能的放大率获得预定的F值。 针对每个可能的放大率,将最佳光圈尺寸存储在存储器中。
