Abstract

A method and associated system for modifying an image on a display screen. A first point and a second point in the image are received from a first interaction and a second interaction, respectively, between a user and the display screen. It is ascertained that a first line and a second line in the image respectively pass through the first point and the second point in the image. The first line and the second line divide the image into a first area, a second area, and a strip area between the first area and the second area. Hiding a portion of the strip area is performed by either removing the visibility of the strip area from the display screen or displaying the portion of the strip area on the display screen in lower resolution than before the hiding is performed.

First claim

What is claimed is:

1. A method for modifying display of an image on a display screen, said method comprising:
displaying an original image on the display screen;
while the original image is being displayed on the display screen, receiving, by one or more processors of a computer system, a selection of a first point in the original image on the display screen, said first point having been selected by the user using a cursor or a finger of the user on the display screen to identify the first point in the original image;
while the original image is being displayed on the display screen, receiving, by the one or more processors, a selection of a second point in the original image on the display screen, said second point having been selected by the user using the cursor or the finger of the user on the display screen to identify the second point in the original image;
after said receiving the first point and the second point, generating on the display screen, by the one or more processors, a first line and a second line in the original image respectively passing through the first point and the second point in the original image, wherein the generated first line and the generated second line visibly define a strip area, a first area, and a second area on the display screen by dividing the original image into the first area, the strip area, and the second area on the display screen, wherein the first area is in direct physical contact with the strip area along the first line, wherein the second area is in direct physical contact with the strip area along the second line, wherein the strip area is disposed between, and in direct physical contact with, the first line and the second line, wherein the first area, the strip area, the second area, the first line, and the second line are being visibly displayed on the display screen as a composite image, wherein the original image encompasses the first area, the strip area, and the second area, wherein first area, the strip area, and the second area are not visibly defined in the original image on the display screen prior to said generating the first line and the second line, wherein the original image and the composite image have a same area and are displayed in an identical area of the composite image, wherein the composite image comprises a closed exterior boundary, and wherein the first line and the second line are each oriented at an acute angle or at an obtuse angle with the closed exterior boundary of the composite image; and
after said generating, hiding, by the one or more processors, a portion of the strip area, wherein said hiding comprises either removing the visibility of the strip area from the display screen or displaying the portion of the strip area on the display screen in lower resolution than before said hiding is performed, and wherein all geometric areas within the original image appear unmagnified and uncompressed in the composite image prior to said hiding.

2. The method of claim 1 , said method further comprising:
detecting, by the one or more processors, a motion of a cursor or a finger of the user on the display screen along a path from the second point toward the first point and ending at a point on the path to define a third line on the display screen passing through the point on the path and being parallel to the second line, wherein the portion of the strip area is disposed between, and in direct physical contact with, the first line and the third line.

3. The method of claim 1 , said method further comprising:
detecting, by the one or more processors, a motion of a cursor or a first finger of the user on the display screen along a first path from the second point toward the first point and ending at a point on the first path to define a third line on the display screen passing through the point on the first path and being parallel to the second line;
detecting, by the one or more processors, a motion of the cursor or a second finger of the user on the display screen along a second path from the first point toward the second point and ending at a point on the second path to define a fourth line on the display screen passing through the point on the second path and being parallel to the first line, wherein the portion of the strip area is disposed between, and in direct physical contact with, the third line and the fourth line.

4. The method of claim 1 , wherein said hiding comprises removing the visibility of the portion of the strip area from the display screen by translating a portion of the first area, a portion of the second area, or both the portion of the first area and the portion of the second area toward the portion of the strip area to cover the portion of the strip area.

5. The method of claim 1 , wherein said determining the first line and the second line comprises:
detecting a motion of a cursor or a finger of the user on the display screen along a first path from the first point and in response, determining that the first line is the first path; and
determining the second line as being parallel to the first line.

6. The method of claim 1 , wherein said determining the first line and the second line comprises:
detecting a motion of a cursor or a finger of the user on the display screen along a first path from the first point and in response, determining that the first line is the first path; and
detecting a motion of a cursor or a finger of the user on the display screen along a second path from the second point and in response, determining that the second line is the second path.

7. The method of claim 1 , wherein said determining the first line and the second line comprises:
determining a direction from the first point to the second point; and
determining the first line and the second line based on the direction.

8. The method of claim 7 , wherein the first line and the second line are each perpendicular to the direction.

9. The method of claim 7 , wherein the first line and the second line are not parallel to each other.

10. The method of claim 7 , wherein the first line, the second line, or both the first line and the second line are curved and not a straight line.

11. The method of claim 7 , wherein the first line is a first straight line and the second line a second straight line.

12. A computer program product comprising one or more computer readable storage devices storing computer readable program code, said program code containing instructions which, upon being executed by one or more processors of a data processing system, implement a method for filtering content received from a search of information, said method comprising:
displaying an original image on the display screen;
while the original image is being displayed on the display screen, receiving, by one or more processors of a computer system, a selection of a first point in the original image on the display screen, said first point having been selected by the user using a cursor or a finger of the user on the display screen to identify the first point in the original image;
while the original image is being displayed on the display screen, receiving, by the one or more processors, a selection of a second point in the original image on the display screen, said second point having been selected by the user using the cursor or the finger of the user on the display screen to identify the second point in the original image;
after said receiving the first point and the second point, generating on the display screen, by the one or more processors, a first line and a second line in the original image respectively passing through the first point and the second point in the original image, wherein the generated first line and the
