Abstract

An image display unit capable of displaying image data page-wise includes: a scanner portion; a display panel for displaying input image data in preview representation; an input condition determiner that compares the image data successively input through the scanner portion, as to input condition and determines whether there is any change in the image data input condition; and a display controller that, when the input condition determiner determines that the input image data has changed in the input condition, makes control such as to display the image data that was determined to have changed in the input condition and the image data input immediately before the image data in question, together on the display panel.

First claim

What is claimed is:

1. An image display unit capable of displaying image data page-wise, comprising:
a storage storing a plurality of successive pages of page-wise image data;
a display panel displaying the image data read from the storage in preview representation; and
a controller performing a determination process that determines whether there is any change in a second input condition of a determination image data as a second image data to be determined in comparison with a first input condition of a reference image data as a first image data, wherein
the determination image data is an image data subsequently stored immediately after the reference image data into the storage, and
when the controller determines that there is a change in the second input condition compared with the first input condition, the controller controls the display panel to display, in parallel, the reference image data and the determination image data side-by-side.

2. The image display unit according to claim 1 , wherein the controller repeats the determination process, after completion of a previous determination process, by replacing the first image data as the reference image data with a second image data as the determination image data and by replacing the second image data as the determination image data with a third image data inputted.

3. The image display unit according to claim 1 , wherein when the controller determines that there is the change in the second input condition compared with the first input condition, the fact that there is the change is warned on the display panel.

4. The image display unit according to claim 1 , wherein the controller controls the display panel to display also the third image data input immediately after the image data that was determined to have changed in the input condition.

5. The image display unit according to claim 4 , wherein the first input condition is one page size of the first image data, and
the second input condition is one page size of the second image data.

6. The image display unit according to claim 4 , wherein the first input condition is color type information used in the first image data, and
the second input condition is color type information used in the second image data.

7. The image display unit according to claim 1 , wherein the first input condition is one page size of the first image data, and
the second input condition is one page size of the second image data.

8. The image display unit according to claim 1 , wherein the first input condition is color type information used in the first image data, and
the second input condition is page size of the second image data.

9. An image forming apparatus including the image display unit according to claim 1 .
