摘要： In a state where no original document is set, light emitted from a light source 6 is received by a sensor 5, a integrated light quantity reference value with which an output is made to be predetermined value V0 is obtained (P1), a magnification of the quantity of light and a gamma correction table are produced from gamma function data for prescanning (P2-1), a quantity of light for prescanning is obtained in accordance with a light quantity adjustment value obtainable from the magnification of the quantity of light and the integrated light quantity reference value and prescanning of a color negative film is performed (P2-2), and an image signal obtained by prescanning is converted with the gamma correction table so as to output image data (P2-3). A magnification of the quantity of light is determined and the gamma correction table is produced from gamma function data for main scanning produced in accordance with image data obtained in prescanning (P3-1), a quantity of light for main scanning is obtained from the magnification of the quantity of light and the integrated light quantity reference value to perform main scanning (P3-2), and the gradient of an image signal obtained from this is further converted with the gamma correction table so as to output mainly-scanned image data (P3-3).

摘要： To provide an image reading apparatus which is capable of easily and quickly specifying a frame of a transparency original for which image reading is desired from the transparency original having a plurality of frames and of image reading with high accuracy at the time of final reading of a specified image. The image reading apparatus comprises: a carrier member holding a film-shaped transparency original which has a plurality of frames; an illuminating means illuminating the transparency original; and an image reading means reading image data of the transparency original illuminated by the illuminating means, in which when the image data is read in previewing, the carrier member is moved by a carrier moving means, and when final image reading of the image data is effected, the carrier member is moved by moving a carrier frame having the carrier moving means. The image data which has been read is outputted to an image display device connected to the image reading apparatus.
