Abstract

PURPOSE:To eliminate the need for re-edition in a computer by adding a picture rotation processing circuit rotating each image data cut out by a cutout circuit by 90 deg. in the unit of cutout and storing the result to an auxiliary storage device. CONSTITUTION:A cutout origin address is obtained from format information 6 to a picture on a picture memory 5 and a picture is cut out by a cutout circuit 7. Whether or not the rotating processing is required to the cut-out area is judged and when required, a picture image rotation processing circuit 13 (rotating processing at each one scanning) is operated. The result of rotating scan is compressed by a compressing circuit 8, the compressed result is stored tentatively in a buffer in the compressing circuit 8, and when the buffer is occupied, the data is outputted to an auxiliary storage device 9. Thus, the picture rotation processing circuit 13 changes its format and attains longitudinal/lateral conversion (90 deg. rotation), then it is not necessary to output data of a picture field while being rotated by 90 deg. in the computer.

,.

Because it requires a large amount of memory. Therefore, compression and extraction of image information is required. Therefore, an image processing apparatus as shown in FIG. 1 has been provided which enables compression and cutting processing.

FIG. 1 is a block diagram showing the configuration of a conventional image processing device. In FIG. The image data input to the image memory 5 is converted into value data and input to the image memo 1/5, and the image is cut out by the cutout circuit 7 according to the format information 6. υ bit compression by the compression circuit 8 according to the rules? The data is stored in the auxiliary storage device 9 in a diagonal form.

Using the above device, if you input 1lli vote 11Th in the format shown in Fig. 2, for example, the output side will output 0 in the format of 5, but the format of the input side 1 and the format of the output side will be When a different output is desired, for example, when inputting data in the format shown in FIG. 2 and outputting the form 12 in the format shown in FIG. 3, the data is edited in the computer and then output.

However, there is a problem in that re-editing an image that requires a large amount of memory in a computer requires a considerable amount of power and time.

(e) Purpose of the Invention The purpose of the present invention is to provide an image processing device which adds an image rotation processing circuit to a conventional image processing device, so that the sheet image is matched with the output image, and which eliminates the need for re-editing within a computer. Our goal is to provide the following.

(d) Structure and object of the invention According to the present invention, there is provided a means for converting an image on a form into binary data, an image memory for storing the converted black and white binary data, and an image field on the image memory. In contrast, in an image processing apparatus having an extraction circuit and a compression circuit that extract and compress according to an input format, and an auxiliary storage device that temporarily stores the output of the compression circuit,
The individual image data cut out by the cutout circuit is sent to the image 1z8 processing device in 90 pieces in cutout units.
0(e) achieved by providing an image processing device characterized by the addition of an image rotation processing circuit for rotating the image and storing it in the auxiliary storage device. Embodiments of the invention will be described in detail with reference to the drawings.

In the present invention, when the input form and output form have different layouts, KgA and vertical/horizontal conversion (90°
In order to enable image rotation, the conventional image processing device shown in Figure 1 rotates the solid image data extracted from the image memory by 90 degrees in units of image data. A processing circuit 13' is added as shown in Figure 4.

FIG. 4 is a block diagram showing the basic structure of the image processing apparatus of the present invention.

In the figure, an image 2 on a form 1 is sent to a preprocessing circuit 4 through an input device (lens, sensor) 3, which converts it into black and white images.
For the image on the zero image memory 5 which is converted into value data and stored in the image memory 5, a cutting origin address is obtained from the format information 6, and the image is cut out in the cutting circuit 7. It is determined whether rotation processing is to be performed for this cut out area based on the format information 6, and if so, the image rotation processing circuit 13 is operated. (Rotation processing for one scan at a time) This rotated scan is compressed by the compression circuit 8, stored in the buffer Kl in the entire compression circuit 8, and output to the auxiliary storage device 49 when the buffer becomes full. do. Note that if there is no rotation instruction in the format information 6, the image rotation processing circuit 13 does not operate and performs the compression process at its own pace. 10 skips the process that reproduces the above operations.

If the above device is used, the image rotation processing circuit 13 inputs the form 11 having the image fields of fA, B, C, v as shown in FIG. It is possible to output to different 7 format forms 12 such as the following.

It is also possible to input all of the forms 14 in formats having image fields A, B, C, D, and E shown in FIG. 5, and output them to the output side as forms 15 in different formats shown in FIG. In this case, image field A
, B, C, D, E can be rearranged on the output side by changing the input order according to the output format, and by rotating only the image field D by 90 degrees.

As described above, when it is desired to output an output in which the format on the input side and the format on the output side are different, the image rotation processing circuit 13 of the present invention allows changing the format and converting the vertical direction (rotation by 90 degrees) to the p1 input. If you manually rotate the image field by 90 degrees at the end, there is no need to input data in the correct order on the input side and rotate the image field 90 degrees in the computer and output it, and the computer side will not be burdened at all. - Data input/output is iiJ function.

(f) Effects of the Invention As explained in detail above, the image processing device of the present invention can change the format of the input side and the formant of the output side by adding an image rotation processing circuit to the conventional image 1 & i processing device valley. When you want to output a different output, you can input it by rotating it by 90 degrees on the input side. There is no need to rotate the data of the image field by 90 degrees inside the machine and output it, as in the past. 1. Data can be input and output without increasing the burden on the machine.
