Abstract

A display control apparatus includes an image display that displays a document image representing a document file; an accepting unit that accepts an operation to point a portion in the document image displayed in the image display; an extracting unit that, upon acceptance of the operation to point the portion in the document image by the accepting unit, extracts each image portion surrounded by pixels other than white pixels from the entire document image if a ratio of the white pixels in the pixels in the document image is higher than or equal to a predetermined threshold value in an area of a predetermined size centered at the pointed portion; and a display controller that performs control so as to display information concerning the image portion having the shortest distance from the portion, among the image portions extracted by the extracting unit, in the image display.

Claims

1. A display control apparatus comprising:

an image display that displays a document image representing a document file;

an accepting unit that accepts an operation to point a portion in the document image displayed in the image display;

an extracting unit that, upon acceptance of the operation to point the portion in the document image by the accepting unit, extracts each image portion surrounded by pixels other than white pixels from the entire document image if a ratio of the white pixels in the pixels in the document image is higher than or equal to a predetermined threshold value in an area of a predetermined size centered at the pointed portion; and

a display controller that performs control so as to display information concerning the image portion having the shortest distance from the portion, among the image portions extracted by the extracting unit, in the image display.

2. The display control apparatus according to claim 1,

wherein the display controller performs the control so as to enhance the image portion having the shortest distance from the portion to display the information concerning the image portion.

3. The display control apparatus according to claim 1,

wherein the display controller performs the control so as to enlarge the document image with the image portion having the shortest distance from the portion being centered to display the information concerning the image portion.

4. The display control apparatus according to claim 1,

wherein the image display displays a number of the image portions extracted by the extracting unit,

wherein the accepting unit accepts an operation to point a portion where the number of the image portions is displayed, and

wherein the display controller performs the control so as to switch the image portion at the center to another image portion to enlarge the document image for display each time the operation to point the portion where the number of the image portions is displayed is accepted by the accepting unit.

5. A display control apparatus comprising:

an image display that displays a document image representing a document file;

an accepting unit that accepts an operation to point a portion in the document image displayed in the image display;

an extracting unit that, upon acceptance of the operation to point the portion in the document image by the accepting unit, extracts each image portion surrounded by pixels other than white pixels from the entire document image if a ratio of the white pixels in the pixels in the document image is higher than or equal to a predetermined threshold value in an area of a predetermined size centered at the pointed portion or in the document image; and

a display controller that performs control so as to display a notification image to indicate a position of the image portion extracted by the extracting unit in the document image in the image display.

6. The display control apparatus according to claim 5,

wherein the accepting unit further accepts an operation to point the notification image displayed in the image display, and

wherein, upon acceptance of the operation to point the notification image by the accepting unit, the display controller performs the control so as to enlarge the document image with the image portion indicated in the notification image being centered for display.

7. The display control apparatus according to claim 5,

wherein, upon acceptance of the operation to point the portion in the document image by the accepting unit, the display controller performs the control so as to enlarge the document image for display and calculate a distance from an end of a display range to the image portion outside the display range and a size of the image portion to display the notification image to indicate the position of the image portion in the document image and the size of the image portion on the basis of the distance and the size that are calculated.

8. The display control apparatus according to claim 7,

wherein the accepting unit accepts an operation to move the display range with respect to the document image, and

wherein, upon acceptance of the operation to move the display range by the accepting unit, the display controller performs the control so as to move the display range and calculate a distance from an end of the display range after the movement to the image portion outside the display range to display the notification image on the basis of the calculated distance.

9. An image forming apparatus comprising:

an image forming unit that forms an image on a recording material on the basis of a document file;

an image display that displays a document image representing the document file;

an accepting unit that accepts an operation to point a portion in the document image displayed in the image display;

an extracting unit that, upon acceptance of the operation to point the portion in the document image by the accepting unit, extracts each image portion surrounded by pixels other than white pixels from the entire document image if a ratio of the white pixels in the pixels in the document image is higher than or equal to a predetermined threshold value in an area of a predetermined size centered at the pointed portion; and

a display controller that performs control so as to display information concerning the image portion having the shortest distance from the portion, among the image portions extracted by the extracting unit, in the image display.

10. A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:

accepting an operation to point a portion in a document image that is displayed in a display and that represents a document file;

extracting, upon acceptance of the operation to point the portion in the document image, each image portion surrounded by pixels other than white pixels from the entire document image if a ratio of the white pixels in the pixels in the document image is higher than or equal to a predetermined threshold value in an area of a predetermined size centered at the pointed portion; and

performing control so as to display information concerning the image portion having the shortest distance from the portion, among the extracted image portions, in the display.

11. A display control method comprising:

accepting an operation to point a portion in a document image that is displayed in a display and that represents a document file;

extracting, upon acceptance of the operation to point the portion in the document image, each image portion surrounded by pixels other than white pixels from the entire document image if a ratio of the white pixels in the pixels in the document image is higher than or equal to a predetermined threshold value in an area of a predetermined size centered at the pointed portion; and

performing control so as to display information concerning the image portion having the shortest distance from the portion, among the extracted image portions, in the display.
