Abstract

PURPOSE:To obtain an attractive outputted result which doesn't any distortion, and which is at an arbitrary position of a foam by storing image information in a main storing device, correcting the distortion after reading out the information, and further correcting the position. CONSTITUTION:An image data 3A is stored in a main storing device 2A. Then, the data is read out, the process of correcting the distortion of the image data for the image data 3B is operated by a distortion correction processing part 7, and the data is stored in a main storing device 2B. Then, an image data 3C stored in the main storing device 2B is read out, and the process of storing the data at the arbitrary position of a main storing device 2C is operated by a position correction processing part 8. Thus, the position of the image information of the image data which doesn't have any distortion can be decided arbitrarily.

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an image processing method, and in particular, for example, in CAD that handles image data, an image processing method that performs correction processing on image data input from an image data input device. This relates to a processing method.

[Prior Art] FIG. 3 is a block diagram showing an example of an image processing device used in a conventional image processing method.

〉 is a CPU that performs image processing, and (6) is a CRT that displays processing results.

Next, the operation of the image processing apparatus used in the conventional image processing method shown in FIG. 3 will be explained.

Image data (3) input from the input device (1) is stored in the main storage device (2). The CPU (5) performs image processing on the image data 3 stored in the main storage device (2), and the data is displayed on the CRT (6) or output from the output device (4).

Next, the fourth section describes conventional image processing performed by the CPU (5).
This will be explained with reference to the figures. In FIG. 4, (3A) is image data input from the input device (1), (2A),
(2B) is the main memory that stores image data, (3
B) and (3C) are image data stored in the main storage devices (2A) and (2B), and (7) is a distortion correction processing unit that corrects distortion of the input image data. Image data (3A) is now stored in the main memory (2A)1
Next, the image data (3B) stored in this main storage device (2A) is read out, and this image data (3B) is
The distortion correction processing unit (7) performs processing to correct the distortion of the image data, and stores it in the main storage device (2B).

Therefore, distortion-free image data (3C) is obtained in the main storage device (2B).

[Problems to be Solved by the Invention] Conventional image processing methods are performed as described above, so that the input image data is free from distortion through distortion correction processing, but its position is not constant, so for example, the output In this case, there is a problem in that the image data is shifted from the center of the paper.

The present invention was made to solve the above-mentioned problems, and an object of the present invention is to provide an image processing method that can arbitrarily determine the position of image information such as image data.

[Means for Solving the Problems] An image processing method according to the present invention includes a first step of storing image information in a main storage device, and reading out the image information stored in the main storage device and performing distortion correction. , a second step of storing the image information in the main memory, and a third step of reading the distortion-corrected image information from the main memory, performing position correction, and storing the image information in the main memory. This is what I did.

[Operations] In this invention, the position correction function allows image information corrected to any position without distortion to be displayed on a CRT or output from an output device.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure is an explanatory diagram showing one embodiment of the present invention, (2A)
, (2B), (3A) to (3C), and (7) are the same as described above. In FIG. 1, (2C) is a main storage device that stores, for example, image data as image information;
(3D) is image data stored in the main storage device (2C), and (8) is a position correction processing unit that performs position correction processing on the image data (3C).

Next, the operation of the embodiment of the present invention shown in FIG. 1 will be explained. Image data (3A) is stored in the main memory (
Distortion correction processing is the process of reading out the image data (3B) stored in the main storage device (2A) and correcting the distortion of the image data for this image data (3B). section (7) and stores it in the main storage device (2B). Therefore, image data (3C) without distortion can be obtained in the main storage device (2B).
C) and stores this image data (3C) in an arbitrary position of the main memory (2C) in the position correction processing unit (8). Therefore, the main memory (2C)
) image data (3D) can be obtained at any position.

Since this image data (3D) has been position corrected, it will not shift from the center of the paper when it is output.

Incidentally, in the above embodiment, the case where image data is used as the image information has been explained for convenience, but other image information such as a photograph or a map may be used. Furthermore, although the distortion correction and position correction processes have been described as separate steps and divided into two stages, the distortion correction and position correction processes may be performed at the same time as shown in FIG.

[Effects of the Invention] As described above, according to the present invention, the first step of storing image information in the main storage device, reading out the image information stored in the main storage device and performing distortion correction, and The method includes a second step of storing the image information in the storage device, and a third step of reading the distortion-corrected image information from the main storage device, performing positional correction, and storing it in the main storage device. Therefore, when the input image information is outputted, there is no distortion, and furthermore, it is located at an arbitrary position on the paper, so there is an effect that an image processing method that produces an output result with good appearance can be obtained.
