Abstract
Abstract Picture frames on a color photographic film (10) are image-picked up with a television camera (44), and the color images of the picture frames are displayed in a matrix arrangement on a color monitor (46a). In order to display color images of picture frames at the same dimension on the color display irrespective of the picture frame size of the color photographic film (10), a specific area from which pixels are picked up is determined in accordance with the picture frame size, and pixel thinning is performed. Pixels for an image taken as a full size on the 135 type color photographic film are thinned every second pixel in both the vertical and horizontal directions, and pixels for an image taken as a half size on the 135 type color photographic film are thinned every second pixel in the vertical direction within the specific area, and the vertical and horizontal addresses are interchanged to read the image data rotated by 90 degrees. Pixels for an image on a 110 type color photographic film are all picked from the specific area as the image data.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
139 words
A method of displaying an image of a picture frame of a color photographic film on image display means, the image being picked up by image pickup means, comprising the steps of: picking up the image data for a large-size picture frame by thinning the pixels within an image pickup area of said image pickup means one pixel out of a predetermined number of pixels, and picking up the image data for a small-size picture frame by picking up all the pixels within a specific area of said image pickup area determined in accordance with the size of said picture frame; writing said picked-up image data into an image memory; and reading said image data from said image memory and supplying said read-out image data to said image display means for display of the image of said picture frame.
Claim 2
Independent Claim
139 words
A method of displaying an image of a picture frame of a color photographic film on image display means, the image being picked up by image pickup means, comprising the steps of: picking up the image data for a large-size picture frame by thinning the pixels within an image pickup area of said image pickup means one pixel out of a predetermined number of pixels, and picking up the image data for a small-size picture frame by picking up all the pixels within a specific area of said image pickup area determined in accordance with the size of said picture frame; writing said picked-up image data into an image memory; and reading said image data from said image memory and supplying said read-out image data to said image display means for display of the image of said picture frame.
Claim 3
Dependent Claim
20 words
A method according to claim 1, said thinning is performed while said image data are written in said image memory.
Claim 4
Dependent Claim
42 words
A method according to claim 1, wherein said image memory is adapted to store said image data for a plurality of picture frames, and said image display means displays said image data for a plurality of picture frames in a matrix arrangement.
Claim 5
Dependent Claim
54 words
A method according to claim 3, wherein said large-size picture frame is a picture frame of a 135 type color photographic film on which images have been taken as a full size, and said small-size picture frame is a picture frame of a 110 type color photographic film on which images have been taken.
Claim 6
Dependent Claim
30 words
A method according to claim 4, pixels for an image of said 135 type full size picture frame are thinned every second pixel in both the vertical and horizontal directions.
Claim 7
Dependent Claim
49 words
A method according to claim 5, wherein pixels for an image taken as a half size on said 135 type color photographic film are thinned every second pixel in the vertical direction, and the vertical and horizontal addresses are interchanged to read said image data rotated by 90 degrees.
Claim 8
Dependent Claim
45 words
A method according to claim 6, wherein said image data with pixel thinned for said 135 half size picture frame are written in a buffer memory, and said image data are read by interchanging the vertical and horizontal addresses and written in said image memory.
Claim 9
Independent Claim
134 words
An apparatus for displaying an image of a picture frame of a color photographic film on image display means, and including image pickup means for picking up said image of a picture frame and an image memory for storing image data of pixels of said image of a picture frame, said apparatus comprising: means for picking up the image data for a large-size picture frame by thinning the pixels within an image pickup area of said image pickup means one pixel out of a predetermined number of pixels, and picking up the image data for a small-size picture frame by picking up all the pixels within a specific area of said image pickup area determined in accordance with the size of said picture frame; and writing said picked-up image data into an image memory.
Claim 10
Independent Claim
134 words
An apparatus for displaying an image of a picture frame of a color photographic film on image display means, and including image pickup means for picking up said image of a picture frame and an image memory for storing image data of pixels of said image of a picture frame, said apparatus comprising: means for picking up the image data for a large-size picture frame by thinning the pixels within an image pickup area of said image pickup means one pixel out of a predetermined number of pixels, and picking up the image data for a small-size picture frame by picking up all the pixels within a specific area of said image pickup area determined in accordance with the size of said picture frame; and writing said picked-up image data into an image memory.
