Abstract:
A light source position adjusting method for externally adjusting position of a light source of an apparatus for imaging photographic film, comprising the steps of:adjusting a position of the light source while the light source is emitting light by externally manually operating a light source moving device, so that quantities of light are uniformly balanced at a plurality of predetermined points on a plane of the photographic film;determining an average value of output light at pixel regions of an image sensor, corresponding to the plurality of predetermined points on the plane of the photographic film;displaying the determined averaged values of the respective pixel regions of the image sensor corresponding to the plurality of predetermined points, and output values of the adjusted light source; andfurther adjusting the position of the light source by externally manually operating the light source moving device while observing the displayed values so that the values of the light output from the respective pixel regions move closer to the averaged output values.
