Color negative inspection apparatus for displaying and sequentially shifting N color positive images corresponding to N color negative frames

Claim 2

A color negative inspection apparatus comprising: means for reading color image data from a frame of a color negative film; memory means for storing color image data sequentially read from N frames of said color negative film by said reading means, N being an integer at least as large as 2; color image display means for displaying N color positive images based on said color image data stored in said memory means, said N color positive images corresponding to said N frames of said color negative film; and means for shifting one color positive image by one frame each time color image data is read from a frame of said color negative film by said reading means.

Claim 3

A color negative inspection apparatus according to claim 1, wherein said color image display means is a single color CRT which displays a plurality of color images on a display surface thereof.

Claim 4

A color negative inspection apparatus according to claim 1, wherein said color image display means is a plurality of color CRTs each of which displays a color image on display surface thereof.

Claim 5

A color negative inspection apparatus comprising: means for reading color image data from a frame of a color negative film; N frame memories for storing color image data sequentially read from N frames of said color negative film by said reading means, N being an integer at least as large as 2; N correction means for correcting said color image data stored in said N frame memories; means for setting amounts by which said N correction means correct said color image data stored in said N frame memories; N color image display means for displaying N color positive images based on said color image data stored in said N frame memories as corrected by said N correction means, said N color positive images corresponding to said N frames of said color negative film; and means for shifting one color positive image by one frame each time color image data is read from a frame of said color negative film by said reading means.

Claim 6

A color negative inspection apparatus comprising: means for reading color image data from a frame of a color negative film; N frame memories for storing color image data sequentially read from N frames of said color negative film by said reading means, N being an integer at least as large as 2; N correction means for correcting said color image data stored in said N frame memories; means for setting amounts by which said N correction means correct said color image data stored in said N frame memories; N color image display means for displaying N color positive images based on said color image data stored in said N frame memories as corrected by said N correction means, said N color positive images corresponding to said N frames of said color negative film; and means for shifting one color positive image by one frame each time color image data is read from a frame of said color negative film by said reading means.

Claim 7

A color negative inspection apparatus according to claim 4, wherein each of said N color image display means is a CRT, and said N CRTs are disposed in an array.

Claim 8

A color negative inspection apparatus according to claim 5, wherein said shifting means comprises N switching circuits for electrically connecting corresponding ones of said N correction means to desired ones of said N CRTs.

Claim 9

A color negative inspection apparatus according to claim 6, wherein said each of said N correction means is a look-up table memory.

Claim 10

A color negative inspection apparatus according to claim 7, wherein color image data newly read from a frame of said color negative film by said reading means is stored in the one of said N frame memories in which the color image data corresponding to the color positive image being displayed at that time on the Nth CRT is stored.

Claim 11

A color negative inspection apparatus according to claim 8, wherein one of said N CRTs is designated as an inspection CRT, and wherein said means for setting correction amounts comprises: memory means for storing original table data; auto correction means for calculating auto correction information for a given frame of said color negative film on the basis of color image data read from said given frame by said reading means; correction key means for inputting manual correction information for said given frame; means for adding said auto correction information to said manual correction information to obtain added correction information; means for reading out said original table data from said memory means and for shifting said read-out original table data in accordance with said added correction information; and means for writing said shifted original table data into one of said N look-up table memories corresponding to one of said N CRTs on which a given color positive image corresponding to said given frame is displayed; wherein said manual correction information is set to zero when color image data is newly read from said given frame by said reading means, and wherein said correction key means is operated to input manual correction information for said given frame while said given color positive image corresponding to said given frame is displayed on said inspection CRT.

Claim 12

A color negative inspection apparatus according to claim 9, wherein said correction key means includes a plurality of density correction keys, a plurality of color correction keys, a plurality of correction level keys, and a plurality of function keys.
