Problems solved by technology

However, if you want to change the size of the output (printed) image, the image will be output in a size completely different from the expected size, resulting in unnecessary waste of recording paper
Especially in the case where image size adjustments must be repeated, a large amount of ink and recording paper may be wasted

Embodiment Construction

[0029] In the following embodiments, the same reference numerals are attached to the same components. Their names and functions are also the same. Therefore, their detailed descriptions are not repeated.

[0030] An image forming apparatus according to an embodiment of the present invention is a digital multifunction peripheral having various functions such as a scanning function, a copying function, a facsimile function, and a printing function. In the following description, "image" means not only the displayed image itself but also image data. "Image data" means not only image data but also character data, data in which images and characters coexist, and the like.

[0031] In the present embodiment, a device having a touch panel disposed on a display panel is used as a touch panel display. The touch panel may be a touch panel of any type such as a resistive film type, a capacitive type, an electromagnetic induction type, an infrared type, or a surface acoustic wave type. ...

Abstract

An operation instructing device includes a display unit that displays an image and a detecting unit that detects a touched position and thereby specifies a corresponding position of an image displayed on the display unit. While an image is displayed on the display unit, if the detecting unit detects that at least two points A and B are touched in a portion of the detecting unit corresponding to the image, assuming that the image is formed on a sheet of recording paper, a distance between two points of the image formed on the sheet of recording paper corresponding to the two touched points is calculated and displayed on a display panel. Thus, an error in operation instruction such as enlargement and reduction can be reduced, and hence, wasteful consumption of ink and recording paper can be reduced.

Description

technical field [0001] The present invention relates to a device for instructing an operation on a displayed image, and more particularly to an operation instructing device capable of instructing zooming in and out of an image by a user's touch operation, an image forming apparatus having the same, and an operation instructing method. Background technique [0002] In recent years, image forming apparatuses (typically copiers) that form images on recording paper have been popularized as one type of image processing apparatuses for electronic equipment. As one type of image forming apparatus, there is a multifunction peripheral (MFP (MultiFunction Peripheral)). The MFP has various functions such as copying, printing, facsimile (hereinafter, facsimile may be referred to as FAX), and scanning. [0003] In an image forming apparatus, an operation panel in which a transmissive touch panel is stacked on the surface of a liquid crystal display panel is often used for easy operation...
