    • A color film reading apparatus of this invention has holding means for holding a color negative film therein; illuminating means for projecting illumination light onto the color negative film; reading means for reading image data from the color negative film; shading correcting means for performing shading correction; and controlling means for controlling the reading means to cause the reading means to read data relative to an unexposed portion of the color negative film to thereby obtain shading correction data for the shading correcting means. The apparatus is capable of generating high-gradation color signals from either of color negative and positive films. This invention further provides an image forming apparatus capable of producing a high-gradation image from either of a film-type original document or a reflection-type original document.

    • A color image reading apparatus for reading an image of a color negative film having: an exposing unit to expose the color film; a reading unit (101) to read an image recorded on the color film by photoelectrically converting the transmission light from the exposed color film; a detector (106-108, 111-113) to detect a density of the image on the basis of an output from the reading unit; and a controller (111, 114) to control an exposure light quantity of the exposing means in accordance with the image density detected by the detector. The detector detects the image density on the basis of a histogram of the output from the reading unit or on the basis of an output of a special color which is output from the reading unit. With this apparatus, the reading operation suitable for the base density and image density of the color negative film can be performed.
    • 一种彩色图像读取设备,用于读取彩色底片的图像,该彩色底片具有:曝光单元,用于曝光彩色胶片; 读取单元(101),用于通过光电转换来自曝光的彩色胶片的透射光来读取记录在彩色胶片上的图像; 检测器(106-108,111-113),用于基于来自读取单元的输出来检测图像的浓度; 以及控制器(111,114),用于根据检测器检测的图像密度来控制曝光装置的曝光光量。 检测器基于来自读取单元的输出的直方图或基于从读取单元输出的特殊颜色的输出来检测图像浓度。 利用该设备,可以进行适合于彩色负片的基本密度和图像密度的读取操作。
