Abstract

A film image editor for editing plural photographic film images. The editor includes: a scanner for reading images in any one of a plurality of different picture sizes from a developed photographic film; a picture size detecting circuit for detecting a picture size of each of the images based on a density variation information of each of the images; an editing interface for editing the image in the detected picture size according to an input operation by an operator; and an output device for outputting the image which is edited by the editing interface.

image reading means for reading an image in a plurality of different picture size that exist in the developed roll of photographic film, including any two of at least a full size, a half-size, a panoramic size, and a low-aspect-ratio size image;

a memory for storing a plurality of density variation reference data which, respectively, correspond to a respective one of a full size image, a half-size image, a panoramic size image, and a low-aspect-ratio size image;

picture size detecting means for detecting a picture size of a selected one of said plurality of photographic film images in said developed roll of photographic film said picture size detecting means including;

density variation detecting means for detecting a density variation pattern of said selected one of said plurality of photographic film images aligned in a predetermined direction, wherein said density variation pattern represents a continuous density variation of a judgment area of said selected one of said plurality of photographic film images along a first length that corresponds to a length of said full size image as measured in one direction that is one of parallel and perpendicular to said predetermined direction; and

a picture size determining means for determining said picture-size of said selected one of said plurality of photographic film images by comparing said density variation pattern with said plurality of density variation reference data stored in said memory means so as to identify said picture-size of said selected one of said plurality of photographic film images;

editing means for editing said selected one of said plurality of photographic film images in said picture size according to an input operation by an operator; and

output means for outputting said selected one of said images edited by said editing means.

2. The apparatus of claim 1, wherein said image reading means comprises:

film reading means for reading said selected one of said plurality of photographic film images from said developed photographic film by scanning said developed photographic film with a line sensor which is moved in a secondary scanning direction while said line sensor scans in a primary scanning direction.

3. The apparatus of claim 1, wherein said density variation detecting means detects said density variation pattern of said selected one of said plurality of photographic film images at a judgment area corresponding to a nonimage recording area of a low-aspect-ratio size image when said image reading means reads an image in a secondary scanning direction.

4. The apparatus of claim 3, wherein said density variation detecting means includes:

binary coding means for coding said selected one of said plurality of photographic film images, which is read by said image reading means, into a binary data; and

pattern detecting means for detecting said density variation pattern based on said binary data.

5. The apparatus of claim 1, wherein said density variation detecting means detects said density variation pattern of said selected one of said plurality of photographic film images at a judgment area corresponding to an area created between two adjacent half-size images in a primary scanning direction which is a perpendicular to said predetermined direction.

6. The apparatus of claim 5, wherein said density variation detecting means includes:

binary coding means for coding said selected one of said plurality of photographic film images, which is read by said image reading means, into a binary data; and

pattern detecting means for detecting said density variation pattern based on said binary data.

7. The apparatus of claim 1, wherein said editing means includes:

a display means for displaying said image in said picture size with an index.

8. The apparatus of claim 1, wherein said editing means includes:

a selecting means for selecting one of a plurality of ones of said image in said picture size by said operator so as to edit said one of said plurality of ones of said image in said picture size.

9. The apparatus of claim 8, wherein said editing means further includes:

arranging means for arranging a layout of a plurality of selected ones of said plurality of photographic film images in one of said picture sizes.

10. The apparatus of claim 8, wherein said selecting means includes:

a cassette means for accommodating a plurality of film holders, each of said film holders holding a plurality of independent positive film frames.

11. The apparatus of claim 8, wherein said selecting means includes:

a cassette means for accommodating a plurality of film holders, each of said film holders holding a film strip including a plurality of continuous negative film frames.

12. The apparatus of claim 1, wherein said editing means includes:

area designating means for designating a color correction area in said selected one of said plurality of photographic film images;

target color selecting means for selecting one of a plurality of predetermined target colors to correct at least one color of said color correction area; and

color correction means for correcting said selected one of said plurality of predetermined target colors of said color correction area to be a selected one of said plurality of predetermined target colors.

13. The apparatus of claim 1, wherein said density variation detecting means detects said density variation pattern of said selected one of said plurality of photographic film images at a judgment area that corresponds to a non-image recording area of a panoramic size image when said image reading means reads an image in a secondary scanning direction which is parallel to said predetermined direction.

14. A film image editing apparatus for editing a plurality of different size photographic film images on a single roll of developed photographic film, comprising:

image reading means for reading an image in any one of a plurality of different picture sizes that exist in the developed roll of photographic film, including a full size image a half-size image, a panoramic size image, and a low-aspect-ratio size image;

picture size detecting means for detecting a picture size of a selected one of said plurality of photographic film images in said developed roll of photographic film;

said picture size detecting means including;

density variation detecting means for detecting a density variation pattern of said selected one of said plurality of photographic film images aligned in a predetermined direction, wherein said density variation pattern represents a continuous density variation of a judgment area corresponding to a non-image recording area of a low-aspect-ratio size image when said image reading means reads an image in a secondary scanning direction; and

a picture size determining means for determining said picture-size of said selected one of said plurality of photographic film images by comparing said density variation pattern with a plurality of stored density variation reference data so as to identify said picture-size of said selected one of said plurality of photographic film images;

editing means for editing said selected one of said plurality of photographic film images in said picture size according to an input operation by an operator; and

output means for outputting said selected one of said images edited by said editing means.
