1. An apparatus comprising:
- a display;
a display controller which controls said display; and
an event generator, coupled to said display controller, which accepts user operation data and generates an event;
said display controller responding to generation of the event by enlarging a predetermined area of said display along a first display direction, the display direction orthogonal to the first display direction remaining unenlarged.

Abstract
A computer system, display device, display controller, and image processing method are described which provide high visibility and usability. A portion of an image displayed on a display screen of the display device is enlarged in one direction and the enlarged image is displayed in a window. In one example, a portion of the image displayed in the display is enlarged in the vertical direction when the text runs along a horizontal direction.

5. A display comprising:
-
an optical output device which produces humanly visible image output;
an input circuit which detects a predetermined input provided from an external source; and
an optical output device controller, coupled to said optical output device and to said input circuit, which enlarges a predetermined image area of said optical output device along a first dimension of said optical output device when said input circuit detects the predetermined input, the image area orthogonal to the first dimension remaining unenlarged. - View Dependent Claims (6)

7. An apparatus comprising:
-
an image display;
an image receiver which receives a first image provided by an external source; and
a display controller, coupled to said image display and to said image receiver, which generates a second image as a function of the first image and generates a third image for output on said image display which third image is enlarged relative to the first image along a first display direction, the display direction orthogonal to the first display direction remaining unenlarged. - View Dependent Claims (8, 9)

10. A display controller comprising:
-
a pointer position identification module which identifies the position of a pointer displayed on a display unit;
an enlargement module which sets a predetermined area of the display unit for enlarged output to the display unit based on the position of the pointer identified by said pointer position identification module; and
an image obtaining module which obtains an image in the area set by said enlargement module;
wherein the enlargement module enlarges the image obtained by said image obtaining module along a first display direction and the display direction orthogonal to the first display direction remaining unenlarged. - View Dependent Claims (11, 12, 13, 15, 16, 19)

14. A computer program for execution on a computer system for controlling a display unit comprising the steps of:
-
detecting a command input from an external source for requesting enlargement;
setting an area in a portion of the display area of said display unit when detecting said request command;
enlarging a character in said area in only one direction relative to said character where the direction is a horizontal direction or a vertical direction; and
outputting image data with the enlarged character.

17. A computer program product comprising:
a computer usable medium having computer readable program code embodied therein which improves the visibility of a display, the computer readable program code in said computer program product effective in executing the steps of;
detecting a command input from an external source requesting enlargement;
retrieving image area data representing a portion of the display when said request command is detected;
enlarging said retrieved image area data in only one predetermined direction, the direction orthogonal to the one predetermined direction remaining unenlarged; and
outputting enlarged image data.

18. A method for processing an image displayed on a display unit, comprising the steps of:
-
setting an area in a portion of an image displayed on the display unit in response to a user request;
retrieving data pertaining to an image in said area;
enlarging the image in said area in one predetermined direction based on said data pertaining to said image, the direction orthogonal to the one predetermined direction remaining unenlarged; and
displaying the enlarged image on the display unit.
