Abstract
Abstract An image reading system (100) prescans and/or scans a film (52) with magnetic recording and image data (54,55) to be stored in a film cartridge (51) after the film (52) is developed. The image reading system (100) employs a one-dimensional CCD (21) and is capable of recording/reading retrievable ID numbers on a magnetic recording part (54). A thumbnail display (Figs. 9, 13A and 13B) simultaneously displays all image and magnetic information of all frames of a film, and selected frames to be scanned can be easily identified and compared after obtaining the image data of such film through prescanning. Magnetic recording information and image information are rapidly read during prescanning and selected frames are then scanned with more refinement as compared to the coarse scanning of the film during prescanning. <MATH>

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
53 words
A method for processing a plurality of frames of a film, each frame having an image section and a magnetic section, said method comprising: prescanning at least one of the image sections and the magnetic sections of the film; and simultaneously displaying a thumbnail display of said plurality of frames on a monitor.
Claim 2
Dependent Claim
25 words
A method for processing a plurality of frames of a film according to claim 1, wherein said prescanning is conducted using a one-dimensional photoelectric converter.
Claim 3
Dependent Claim
35 words
A method for processing a plurality of frames of a film according to claim 1, further comprising displaying information relating to each magnetic section adjacent each of said plurality of frames displayed on the monitor.
Claim 4
Dependent Claim
31 words
A method for processing a plurality of frames of a film according to claim 1, wherein said prescanning includes prescanning said image sections and said magnetic sections at a constant speed.
Claim 5
Dependent Claim
38 words
A method for processing a plurality of frames of a film according to claim 1, further comprising orienting each image in the thumbnail display in accordance with magnetic display information contained in each magnetic section of the film.

A method for processing a plurality of frames of a film according to claim 1, further comprising selecting at least one frame from said thumbnail display for scanning; and scanning said at least one selected frame.
Claim 7
Dependent Claim
25 words
A method for processing a plurality of frames of a film according to claim 8, wherein said scanning is conducted using a one-dimensional photoelectric converter.
Claim 8
Dependent Claim
34 words
A method for processing a plurality frames of a film according to claim 6, further comprising writing a magnetic identification number on the magnetic section of said at least one frame selected for scanning.
Claim 9
Dependent Claim
33 words
A method for processing a plurality of frames of a film according to claim 6, further comprising changing at least one photographic condition of at least one of said prescanned images before scanning.
Claim 10
Independent Claim
57 words
An apparatus for processing a plurality of frames of a film, each frame having an image section and a magnetic section, said apparatus comprising: means for prescanning at least one of the image sections and the magnetic sections of the film; and means for simultaneously displaying a thumbnail display of said plurality of frames on a monitor.
Claim 11
Dependent Claim
24 words
An apparatus for processing a plurality of frames of a film according to claim 10, wherein said prescanning means includes a one-dimensional photoelectric converter.
