ABSTRACT:
A film image signal generation apparatus, includes: a film displacement device which displaces a developed film which has a magnetic recording layer to an image area; an image signal conversion device which converts an image of a film frame which is opposed to the image area into a first image signal; a magnetic writing device which rewrites old data written in the magnetic recording layer of the film into new data; a data storage circuit which stores the old data and the new data; an image signal generation circuit which generates a second image signal which shows data change information, based upon the old data and the new data which are stored by the data storage circuit; and a control circuit which controls the magnetic writing device, the data storage circuit, and the film displacement device so as to rewrite the old data which is recorded upon the magnetic recording layer into the new data which is stored in the storage circuit, and controls the image signal conversion device and the image signal generation circuit so as to output the second image signal at a predetermined time.
