ABSTRACT:
An image reading apparatus for reading images on films of different sizes and outputting read image data includes a film sensor for sensing the dimension of at least one side of each film and a control module for operating the apparatus so that at least one of the reading process and outputting process is performed under a parameter setting set beforehand in accordance with a signal from the film sensor. When a reading start instruction is issued from a control panel, a film width detecting circuit performs film sensing, thereby determining the film width of each film. Based on the film width, reading parameter values such as a pixel pitch, a density range, and a data transfer destination are selected from among those that are beforehand set through the control panel. Table update is made for a density linear conversion table according to the film width and an interpolation coefficient according to the pixel pitch. Each film is read through a halogen driving circuit and an actuator driving circuit, and the image data is output through an image data reading circuit.
