摘要： In an image read apparatus which reads an image from a recording medium, such as a film, and outputs image data, and shading correction data is set. Time elapsed since the shading correction data is set is counted. Before performing main scanning, whether or not the elapsed time is longer than a predetermined period is determined, and if it is, the shading correction data is updated. The read image data is processed with shading correction using the shading correction data which is updated as time elapses.

The device includes: a light source to generate a light beam which is irradiated to the optical recording medium; a polarizing or non-polarizing beam splitter, arranged on the optical path from the light source to the recording medium and consisting of prisms, for transmitting the light beam from the light source and leading to the recording medium, and for separating the light reflected by the recording medium from the light beam from the light source; and photodetectors, arranged almost rectilinearly, for receiving the reflected light from the recording medium which is separated by the beam splitter, wherein among the planes of the beam splitter, the plane opposite to the plane which faces the direction of the photodetectors has a shape adapted to lead the light beam reflected by this plane to the direction which is almost perpendicular to the arrangement direction of the photodetectors. With this apparatus, the signals can be detected with a high S/N ratio.
