Thus, the smooth picture input is attained and the load of the user is relieved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing apparatus equipped with a manual image input device.

[Conventional technology]

In recent years, with the development of highly integrated technology in the electronics industry,
Many small, high-performance electronic devices have been developed and commercialized. Image input devices are no exception, especially manual image input devices called handy scanners.
Because it is small and easy to operate, it is used as an input device for image processing devices.

[Problem to be solved by the invention]

However, since the reading width of the internal manual image input device is 10c11 to 15cII, there is a drawback that the width of the read manuscript/original image is limited thereby. FIGS. 4 to 6 are explanatory diagrams showing operating states of the manual image input device. In FIG. 4, 1 is a manual image input device, and 2 is a document. Normally, the operating direction of the manual image input device 1 is vertical, so as shown in FIG.
If the reading range n is smaller than the readable width 1 of the manual Ij image input device 1, the reading range n can be input without problems. However, as shown in FIG. 5, if the reading range n is larger than the readable width 1, an unreadable range m remains.

In the case of Figure 5, the solution is to (1) change the number of originals 2 to 90
degree to operate the manual image input device 1 in the vertical direction.

(2) As shown in FIG. 6, leave the original N2 as it is and operate the manual image input device 1 laterally. Possible methods include: However, method (1) is inappropriate when the orientation of the document cannot be changed, and method (2) is
If you display this as is on the image display device, the original will be 9
This results in a vertical image rotated by 0 degrees. in this case,
The user must perform a rotation operation using the image processing device to orient the document in the same horizontal direction as the original document.

This is a very troublesome operation and places a heavy burden on the user.

The present invention provides an image processing device that enables smoother image input and reduces the burden on the user by adding a function to control image rotation to the image processing unit of the image processing device. With the goal.

[Means and effects for solving the problem] Image processing according to the present invention 3! ! ! The apparatus includes a manual image input means for reading a document, a storage means for storing and processing images input from the manual image input means, and an image input device by vertically operating the manual image input means. and image processing means for rotating or non-rotating an image input in one of the lateral direction operations based on a preset instruction. As a result, the rotation and non-rotation of the input image will be automatically controlled based on the instructions set in advance, so if the image is input by vertical operation, the image will be non-rotated and the image will not be rotated vertically. Is displayed. On the other hand, if an image is input by a horizontal operation, the image will be displayed rotated by 90 degrees, that is, in the horizontal direction.

〔Example〕

FIG. 1 is an overall configuration diagram showing an embodiment of an image processing apparatus according to the present invention. The manual image input device 1 inputs a document/
This manual image input device W1 is a handy scanner that reads an image from an original image and converts it into an electrical signal.
The image data read by the computer 1 is stored in the storage device 3 via the system bus. The image processing unit 4 is a CPU
and a main storage device, etc., and controls the rotation and non-rotation of the image read from the memory Vt13 in response to the instruction of the operating direction of the manual image processing device V11. The operating direction of the manual image input device 1 is displayed on the pit map type image display device ff5 as shown in FIG. A horizontal input display 8 and a vertical input display 9 are displayed on the screen of the image display device 5, and the user is configured to select one of them and give an instruction. In FIG. 1, reference numeral 6 is a keyboard that is a means for inputting characters and coordinates, and reference numeral 7 is a mouse that directly instructs image display on the image display device 5.

According to the above configuration, the image display 'gei5 is activated by selecting the displayed menu (horizontal input display 8, vertical input display 9) and giving an instruction using the keyboard 6 or mouse 7 to the image processing unit. 4, the image processing apparatus can control rotation and non-rotation of the image.

Next, the image control processing procedure in the above-mentioned image processing unit 4 will be explained based on the flowchart of FIG. 3.

First, before performing the operation shown in FIG.
As shown in the figure, the image input direction is displayed on the image display device 5. Next, when the user selects an input direction and instructs the input direction (step 101), it is determined whether or not image input by the manual image input device 1 has started (step 102). A loop is executed while image input is not started, and when image input is started, image data for one line of the image is read from the manual image input means 1 (step 103), and the input image data is transferred to the system bus. is sequentially transferred to the storage device 3 and stored therein (
Step 104). Next, it is determined whether or not the image input has been completed.Step 1o5) If the image input has not been completed, the process returns to step 103, and when the image input has been completed, the input direction of the image is indicated as "horizontal". It is determined whether or not it has been done (step 106). If "horizontal" is specified, the image data read from the storage device 3 is subjected to coordinate transformation and image rotation processing is performed (step 107), and the image is displayed on the image display device 5 (step 108).
. At this time, the image is displayed horizontally on the screen. Furthermore, if the input direction of the image is not specified as "horizontal" in step 106, the image is displayed as it is on the image display device 5 without performing rotation processing on the image data read out from the storage device @3 (step 108). The image at this time is displayed vertically on the screen.

In the image processing device in this embodiment, the input direction of the image is displayed on the image display device in advance before operating the manual image input device, so the user can easily specify the input direction of the image using the keyboard or mouse. According to
This allows image rotation and non-rotation operations.

In the above embodiment, a case has been described in which two image input directions are displayed on the screen of the image display device 5, but the image input direction is not displayed and an input direction instruction is directly given to the image threat processing unit 4. You can do it like this.

Furthermore, the storage device 3 may be built into the main body of the image processing section 4, or the storage device 3 may be built into the main body of the image processing section 4, or
It may be possible to use the A device.

〔Effect of the invention〕

As explained above, in the present invention, the image processing unit of the image processing device is added with the function of controlling the rotation of the image,
Since the image processing section is configured to control the rotation and non-rotation of the image based on the instruction of the operating direction of the manual image input device set in advance, the operation can be simplified. Therefore, smoother image input is possible, and the burden on the user can be reduced.
