Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for displaying a preview screen for displaying a read image in a scanner for reading a read image.

[0002]

2. Description of the Related Art In a floodbed scanner, the maximum size of a document to be read is limited, so that a preview screen can be designed according to the maximum size of the document.
However, in a device that can be freely loaded such as a freehand scanner, the size of the original is theoretically unlimited, so the design of the preview screen is to display the current position where the scanner is scanning at almost the center of the preview screen, and In order to display scrolling up, down, left and right in accordance with the movement, or to always display all the read images, the display is performed while reducing the image.

[0003]

However, as for the scroll display, there is a problem that the whole image is difficult to grasp because the displayed image is displayed mainly on the image being scanned and the protruding image is not displayed on the screen. Further, with respect to the reduced display, there is a problem that the displayed image becomes smaller as the scanning range becomes wider, so that it is difficult to confirm details of the image.

[0004]

In order to solve the above-mentioned problems, in the method of displaying a preview image according to the present invention, two types of display modes, a scroll display mode and a reduced display mode, are incorporated, and according to a user setting, By incorporating a function capable of switching between the scroll display mode and the reduced display mode, or displaying the scroll display mode and the reduced display mode simultaneously, a display mode that is easier for the user to understand can be selected.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An image input device according to a first aspect of the present invention is a scanner for reading a read image,
A scroll display mode for scrolling the preview screen so that the image at the current scanning position is always displayed on the preview screen when scanning is performed outside the preview screen that displays the image read by the scanner; and a reduced display of the preview screen. And a reduced display mode for always displaying the entire read image on the preview screen.

Next, the image input device according to a second aspect of the present invention is configured such that the two types of preview screens of the scroll display mode and the reduced display mode can be selectively changed in real time during image reading. The display mode and the reduced display mode can be switched in real time during reading.

Next, the image input device according to a third aspect of the present invention reads the image in the scroll display mode during image reading, and displays the entire read image on the entire preview screen in the reduced display mode after the image reading is completed. Is what you do.

Next, an image input apparatus according to a fourth aspect of the present invention secures a display area of the preview screen for a plurality of screens and simultaneously displays the two types of preview screens.

Next, an image input device according to a fifth aspect of the present invention is the image input device according to the second, third, or fourth aspect, and has a combination of at least two or more functions. The function can be selected by a user.

[0010] Next, the preview image display method according to claim 6 of the present invention is characterized in that, in a scanner for taking in a read image, when a scan is carried out beyond a preview screen for displaying the image read by the scanner, the preview screen is displayed. And a scroll display mode in which the image at the current scanning position is always displayed on the preview screen, and a reduced display mode in which the preview screen is reduced and the entire read image is always displayed on the preview screen.

Next, a preview image display method according to a seventh aspect of the present invention is capable of selectively changing the two types of preview screens of the scroll display mode and the reduced display mode in real time during image reading. It is.

Next, in the preview image display method according to an eighth aspect of the present invention, the image is read in the scroll display mode during image reading, and the entire image read after completion is displayed on the entire preview screen in the reduced display mode. To display.

Next, a preview image display method according to a ninth aspect of the present invention secures a display area of the preview screen for a plurality of screens and simultaneously displays the two types of preview screens.

According to a tenth aspect of the present invention, there is provided a method for displaying a preview screen of an image input device according to the seventh, eighth, or ninth aspect of the present invention. It has a combination of functions and allows the user to select the function.

(Embodiment 1) An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. Figure 1
FIG. 2 is a diagram illustrating a configuration diagram of an image input device. 1 is an image scanner, 2 is a personal computer that receives the read image, and 3 is a display that displays the image. Image data read by the image scanner 1 is sent to the personal computer 2, and the received image is displayed on the display 3. A preview screen 4 displays the received image in this area. The scroll display will be briefly described with reference to FIG. 5a is a read original. Reference numeral 1a denotes a position of the scanner at the start of reading, a position advanced after a predetermined time is 1b, and a preview screen at that time is 4a. The further advanced position is 1c, and the preview screen at that time is 4b. Since the preview screen has moved to a position protruding beyond the preview screen at the time of the scanner 1c, the preview screen 4
The image of b is scrolling right.

The reduced display will be briefly described with reference to FIG. 5b is a read original. 1d is the position of the scanner at the start of reading, and the position advanced after a certain time is 1
In e, the preview screen at that time is 4c. The further advanced position is 1f, and the preview screen at that time is 4d. At the time of the scanner 1f, the image has been moved to a position beyond the preview screen, so that the image on the preview screen 4b is displayed in a reduced size.

The above two display modes, scroll display and reduced display, can be switched by a user's key input or the like.

FIG. 4 is a diagram showing an example of the image of switching the display mode by key input. As the keys to be used, a keyboard attached to the personal computer may be used, or a button for switching display may be incorporated in the scanner.
By switching the display mode in one preview screen in this manner, the image can be easily confirmed even in a PC having a relatively small display area.

When the reading is completed in the scroll display mode, the preview screen is automatically switched to the reduced display mode, so that the entire read image can be confirmed.

(Embodiment 2) FIG. 5 is a diagram showing an example of an image in which a scroll display preview screen and a reduced display preview screen are simultaneously displayed. These two types of preview screens are displayed in real time during image reading. By displaying the two types of preview screens simultaneously, it is easy to confirm the image on a personal computer having a relatively large display area. It is needless to say that one preview screen can be divided into two as shown in FIG. 6 and scroll display and reduced display can be displayed respectively. The use of this method is also effective when the display device is not a display connected to a personal computer but displays on a small liquid crystal incorporated in a scanner.

[0021]

As described above, according to the image reading of the present invention, the preview screen during the image reading can be displayed in a manner that is easy for the user to confirm.
