Image Processing Apparatus, Computer Program Product, and Preview Image Displaying Method

Abstract

In an image processing apparatus, preview images are generating by continuously scanning both sides of originals. The page scrolling unit scrolls the preview images while pairing a first preview image to be processed with a second preview image that is not processed as pages of front and back sides of an original or a two-page spread, and a preview displaying unit displays at least one of the first preview image and the second image.

1 . An image processing apparatus comprising:
 a preview image generating unit that generates preview images by continuously scanning both sides of originals;   a page scrolling unit that scrolls the preview images while pairing a first preview image to be processed according to a predetermined setting with a second preview image that is not processed as pages of any one of front and back sides of an original and a two-page spread; and   a preview displaying unit that displays at least one of the first preview image and the second image.   
     
     
         2 . The image processing apparatus according to  claim 1 , further comprising a process setting position changing unit that changes a process setting position on the first preview image for performing a process according to the predetermined setting depending on whether the first preview image is on a front side or a back side of the original when the process setting position changes between the front side and the back side in the process. 
     
     
         3 . The image processing apparatus according to  claim 2 , further comprising a notifying unit that notifies a user of a variation in the process setting position between the front side and the back side. 
     
     
         4 . The image processing apparatus according to  claim 1 , wherein the page scrolling unit scrolls the preview images in units of any one of front and back sides of an original and the two-page spread, while switching the first preview image and the second preview image. 
     
     
         5 . The image processing apparatus according to  claim 1 , further comprising a switching unit that switches the first preview image and the second preview image that is paired with the first preview image. 
     
     
         6 . The image processing apparatus according to  claim 1 , wherein the preview displaying unit displays the first preview image and the second preview image to be arranged adjacent to each other. 
     
     
         7 . The image processing apparatus according to  claim 6 , wherein the preview displaying unit displays the first preview image and the second preview image in a shape like a folding screen. 
     
     
         8 . The image processing apparatus according to  claim 6 , wherein the preview displaying unit displays the first preview image to be larger than the second preview image. 
     
     
         9 . The image processing apparatus according to  claim 1 , wherein the preview displaying unit entirely displays the first preview image, and partially displays the second preview image. 
     
     
         10 . The image processing apparatus according to  claim 1 , wherein the preview displaying unit displays the second preview image transparently with respect to the first preview image. 
     
     
         11 . The image processing apparatus according to  claim 1 , wherein the preview displaying unit displays the second preview image as a mirrored image with respect to the first preview image. 
     
     
         12 . The image processing apparatus according to  claim 1 , wherein the preview displaying unit displays only the first preview image. 
     
     
         13 . The image processing apparatus according to  claim 12 , further comprising a replacing unit that replaces the first preview image with the second preview image. 
     
     
         14 . The image processing apparatus according to  claim 1 , wherein the preview displaying unit further displays other preview images on prior and next pages of a pair of the first preview image and the second preview image. 
     
     
         15 . The image processing apparatus according to  claim 1 , wherein the preview displaying unit displays the second preview image with a symbol image. 
     
     
         16 . The image processing apparatus according to  claim 1 , further comprising a rotation unit that rotates, when a shorter side of a preview image is specified as an axis of the two-page spread, the preview image by  90  degrees with respect to a preview image whose longer side is specified as an axis of the two-page spread. 
     
     
         17 . A computer program product comprising a computer usable medium having computer readable program codes embodied in the medium that, when executed, causes an image processing apparatus to execute:
 generating preview images by continuously scanning both sides of originals;   scrolling the preview images while pairing a first preview image to be processed according to a predetermined setting with a second preview image that is not processed as pages of any one of front and back sides of an original and a two-page spread; and   displaying at least one of the first preview image and the second image.   
     
     
         18 . The computer program product according to  claim 17 , further causing the image processing apparatus to execute, changing a process setting position on the first preview image for performing a process according to the predetermined setting depending on whether the first preview image is on a front side or a back side of the original when the process setting position changes between the front side and the back side in the process. 
     
     
         19 . The computer program product according to  claim 18 , further causing the image processing apparatus to execute, notifying a user of a variation in the process setting position between the front side and the back side. 
     
     
         20 . A preview image displaying method comprising:
 generating preview images by continuously scanning both sides of originals;   scrolling the preview images while pairing a first preview image to be processed according to a predetermined setting with a second preview image that is not processed as pages of any one of front and back sides of an original and a two-page spread; and   displaying at least one of the first preview image and the second image.
