DISPLAY DEVICE
First Claim
1. A display device, comprising:
- a display panel having a rectangular display region with a first area, and having a longer side and a shorter side with an aspect ratio of a (a>
1);
a reading unit that reads a rectangular original image; and
a control unit that controls display of the original image on the display panel, whereinthe control unit includes;
a magnified-image producing unit that magnifies the original image by a predetermined scale to produce a magnified image;
an image defining unit that divides the magnified image by a divisional line extending in parallel with either one of a longer side direction and a shorter side direction, to define a partial magnified image having a predetermined width and an area equal to or less than the first area; and
a display control unit that displays a whole of the partial magnified image in the display region.

Abstract
A display device has a display panel, a reading unit, and a control unit. The display panel has a rectangular display region with a first area, and having a longer side and a shorter side with an aspect ratio of a (a>1). The reading unit hat reads a rectangular original image. The control unit controls display of the original image on the display panel. The control unit includes a magnified-image producing unit, an image defining unit, a display control unit. The magnified-image producing unit that magnifies the original image by a predetermined scale to produce a magnified image. The image defining unit that divides the magnified image by a divisional line extending in parallel with either one of a longer side direction and a shorter side direction, to define a partial magnified image having a predetermined width and an area equal to or less than the first area. The display control unit displays a whole of the partial magnified image in the display region.

7. A device comprising:
-
a display unit having a rectangular data display region; a reading unit that reads original image data corresponding to a rectangular original image; a magnified-image producing unit that produces magnified image data from the original image data according to a magnification scale inputted by a user for displaying magnified image which is magnified with the original image; and a control unit that outputs at least a part of the magnified image data or the original image data to the display unit and displaying either the at least a part of the magnified image or the original image in the data display region, characterized by further comprising; an image determination unit that divides the magnified image in a first direction to define a partial magnified image having a predetermined width, the first direction being either one of a longitudinal direction and a lateral direction, wherein the partial magnified image includes a range from one end through the other end in a second direction orthogonal to the first direction, and has an area equal to or less than an area of the data display region, and the control unit outputs a part of the magnified image data corresponding to the partial magnified image to the display unit, thereby displaying the partial magnified image in the data display region as a whole. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
