Device capable of displaying window size and position

A device having a window display function, comprising:

• display means having a visual screen for displaying image data;
• window display means for controlling said display means such that a portion of an image screen is displayed on said visual screen, through a window set on said image screen;
• and
• indicia display means for controlling said display means so as to display indicia on said visual screen, said indicia indicating a positioned and size relationship between said window and a window-movable region on said image screen, in which said window can move and/or change its size, wherein said indicia includes first to fourth patterns, a ratio of the length of said first pattern to that of said second pattern being equal to the ratio of the length of said window to the length of said window-movable region, the ratio of the length of said third pattern to that of said fourth pattern being equal to a ratio of the width of said window to the width of said window-movable region, a position relationship between said first pattern and said second pattern corresponds to a position relationship between said window and said window-movable region, with respect to the horizontal direction, a position relationship between said third pattern and said fourth pattern corresponds to a position relationship between said window and said window-movable region, with respect to the vertical direction.

• window display means for controlling said display means such that a portion of an image screen is displayed on said visual screen, through a window set on said image screen;
• and
• indicia display means for controlling said display means so as to display indicia on said visual screen, said indicia indicating a positional and size relationship between said window and a window-movable region on said image screen, in which said window can move and/or change its size, wherein said indicia includes a first display region, a first display pattern, a second display region, and a second display pattern:
• said first display pattern being displayed in said first display region, said second display pattern being displayed in said second display region, a ratio of the length of said first display pattern to that of said first display region is equal to the ratio of the length of said window to the length of said window-movable region, the ratio of a length of said second display pattern to that of said second display region is equal to a ratio of the width of said window to the width of said window-movable region, a position of said first pattern displayed in said first display region corresponds to a position of said window set on said window-movable region, with respect to a horizontal direction, and a position of said second pattern displayed in said second display region corresponds to a position of said window set on said window-movable region with respect to a vertical direction.

A method of displaying a window status, comprising the steps of:

• displaying a portion of an image screen on a visual screen through the window set on the image screen, and
• displaying an indicia on said visual screen, said indicia representing a positional relationship and size relationship between said window and a window-movable region on said image screen, where said window can move or change its size, wherein said indicia includes a first display region, a first display pattern, a second display region, and a second display pattern;
• said first display pattern being displayed in said first display region, said second display pattern is displayed in said second display region, a ratio of the length of said first display pattern to that of said first display region is equal to the ratio of the length of said window to the length of said window-movable region, the ratio of a length of said second display pattern to that of said second display region is equal to a ratio of the width of said window to the width of said window-movable region, a position of said first pattern displayed in said first display region corresponds to a position of said window set on said window-movable region, with respect to a horizontal direction, a position of said second pattern displayed in said second display region corresponds to a position of said window set on said window-movable region with respect to a vertical direction.
