Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus for processing images such as characters and figures.

[Prior Art] Conventionally, in a personal computer or the like, an output pattern such as a kanji character or a graphic desired by a user can be arbitrarily created and registered. In this case, the following two methods are known. I have.

That is, a method of inputting data one dot at a time from a keyboard and creating an output pattern while developing it on a display screen, or a method of reading an original image with an image reader and using this image data as an output pattern is generally known. ing.

[Problems to be Solved by the Invention] However, in the former method, since an output pattern is created while inputting data one dot at a time, pattern creation is extremely troublesome and requires a great deal of labor. At the same time, it requires a sense of balance in character shapes and design-related skills.

Also, in the latter method, in order to obtain an output pattern of an arbitrary size, it is necessary to enlarge or reduce the original image by photoengraving, which requires labor and requires an output of a desired size. It was extremely difficult to reliably obtain the pattern.

An object of the present invention is to easily specify a print output size when an arbitrary portion of an image is printed out at a specified size, and to confirm the output size when specifying a desired image portion. Thus, a print image of a desired size can be obtained.

[Means for Solving the Problems] According to the present invention, an image processing apparatus includes a registration unit (1) for registering an image of a predetermined size in advance, and a designation unit (2) for designating an image registered in the registration unit. And determining means for determining an area on the display screen, which is an image cut-out range, based on the display screen and the resolution of the printer so that the size of the image specified by the specifying means is obtained.
And an area image representing the cut-out area determined by the determining means is movably displayed on a screen on which a new image is displayed, and the cut-out means (Cropping means) cuts out an image of a portion specified by the displayed area image. (Refer to the functional block diagram of FIG. 1) [Embodiment] An embodiment will be described below with reference to FIGS. 2 to 6.

FIG. 2 is a block diagram showing the overall configuration of the output pattern creation device.

The image reader 11 outputs the output pattern (logo,
The input control unit 12 controls the reading operation of the image reader 11 and transfers the image data read by the image reader 11 to the input buffer 13.

The input designating device 14 includes a keyboard 14-1 and a mouse 14-2. In order to instruct creation of an output pattern having an arbitrary size based on image data read by the image reader 11, the output size and the like are set in advance. Is specified. In the present embodiment, the dot size (32 × 32 dots,
164 x 64 dots, etc.), and the letter face size of characters, figures, etc., that make up the created pattern is specified and entered in mm. Thus, the output size specified and input by the input specifying device 14 is provided to the cutout control unit 16 via the input specification control unit 15.

The cutout control unit 16 outputs the output size (dot size, letter face size) specified by the input specifying device 14
And input buffer based on printer resolution (240dpi)
When extracting the image data in 13, the extraction box size is determined. Based on the determined extraction box size, the X size and Y direction extraction to specify the X direction extraction range of the XY coordinate system The image is divided into Y sizes for specifying the range, and transferred to the corresponding Y division control unit 17 and X division control unit 18. In addition, the cutout control unit 16 transfers display frame data corresponding to the determined cutout box size to the display buffer 22.

The Y division control unit 17 and the X division control unit 18 cut out image data while specifying the X and Y cutout positions when cutting out the image data in the input buffer 13. Is transferred to the display buffer 22, and then output from the CRT display device 23. In this case, display frame data corresponding to the cut-out box size determined by the cut-out control unit 16 is set in the display buffer 22.
The image data from 13 is displayed and output.

Further, the image data cut out from the input buffer 13 is subjected to resolution conversion by the resolution conversion device 19 and then transferred to the output buffer 20 as an output pattern. That is, the resolution conversion device 19 creates an output pattern having an arbitrary predetermined output size by performing resolution conversion of image data according to various parameters sent from the cutout control unit 16, The output pattern created in this way is transferred to the output buffer 20. The output pattern in the output buffer 20 is registered in the font file memory 21 or printed out from the printer 25 via the printer buffer 24. Read out in response to the output buffer
After being transferred to the printer 20, the print data is output from the printer 25 via the printer buffer 24. When an output pattern is registered in the font file memory 21, the output pattern is registered in the font file memory 21 together with the identification code.

On the other hand, when a new output pattern having the same size as that of the created output pattern (registered pattern registered in the font file memory 21) and the letter face is newly created, the input designating device 14 designates the call of the registered pattern. . Then, after the designated registration pattern is read from the image reader 11 and taken into the font file reading buffer 26, the registration pattern is transferred to the output size analysis unit 27.

The output size analysis unit 27 analyzes the output size (letter face size) of the registered pattern, determines the output size (letter face size) of the pattern newly created this time, and gives the output size to the cutout control unit 16. In this case, the cutout control unit 16 determines the cutout box size of the image data based on the output size determined by the output size analysis unit 27 instead of the output size specified by the input specifying device 14.

Next, the operation of the present embodiment will be described with reference to FIGS.

FIG. 3 is a flowchart showing the operation when the output size is specified from the input specifying device 14.

First, when an arbitrary original image prepared in advance is read by the image reader 11, the read image data is written to the input buffer 13 by the input control unit 12 (step A1). Then, the image data in the input buffer 13 is transferred to the display buffer 22, and displayed and output from the CRT display device 23 (step A2). FIG. 4A shows a display state in this case, and the read image data is directly displayed and output as shown in FIG. 4A.

Next, in order to specify the size of the output pattern (logo mark) to be created, the dot size is specified (step A3). For example, if a desired dot size is selected and designated from the input designation device 14 from among dot sizes such as 16 × 16 dots, 32 × 32 dots, and 64 × 64 dots prepared in advance, the designated dot size is designated by the input designation. Control unit 15
Is transferred to the cutout control unit 16. Then, the letter face size of characters, graphics, etc., constituting the output pattern to be created is inputted from the input designating device 14 (step
A4). In this case, the letter face size when actually printed is entered in mm. FIG. 5 shows a case where 7 mm is specified as the letter face size of the character "C". The thus input letter face size is transferred to the cutout control unit 16 by the input designation control unit 15.

Then, the process proceeds to the next step A5. In order to indicate which character is displayed on the CRT screen and in which size the letter "C" specifying the letter face size is displayed, the input designation device 14 displays the letter face size on the CRT screen. Is designated by the box size (see FIG. 4 (B)). Then, the cutout control unit
16 counts the number of dots on the CRT screen corresponding to the designated letter face size.

Then, in the next step A6, a cutout box size is determined, and a display frame (cutout box) corresponding to the size is displayed and output at a predetermined position on the CRT screen. Here, the designated dot size is A dot, the designated letter face size is Bmm, and the resolution of the printer 25 is 240 dp.
If i (dots per inch) and the number of dots corresponding to the letter face size Bmm on the CRT screen are C dots, the number of dots on the CRT screen corresponding to the cutout box is Becomes

As a result, the cutout box determined on the CRT screen is displayed at a predetermined position.

Then, proceed to the next step A7, in order to adjust the position of the cutout box, move the cutout box on the CRT screen using the keyboard 14-1 or the mouse 14-2 and move the position as shown in FIG. 4 (C). After the matching, the position of the cutout box is determined by mouse operation or key operation. That is, the determined cutout box is not always displayed with the center of the character “C” at the center, and therefore, the movement of the cutout box is adjusted.

Then, the resolution conversion device 19 converts the resolution of the image data in the cutout box read from the input buffer 13 to create an output pattern, and transfers it to the output buffer 20 (step A8). In this case, the resolution conversion rate is Bmm for the designated letter face size and 240 for the resolution of the printer 25.
If the dot number of the part corresponding to the letter size Bmm on the dpi and CRT screen is C dot, Becomes

As a result, an output pattern having a desired size is obtained and registered in the font file memory 21 (step A9). The created output pattern in the output buffer 20 is printed out from the printer 25 in response to the print command.

FIG. 6 is a flowchart showing the operation when newly creating an output pattern having the same size as a created output pattern (registered pattern) registered in the font file memory 21.

First, similarly to steps A1 to A3 in FIG. 3, when an arbitrary original image is read by the image reader 11, the read image data is written into the input buffer 13 (step B1) and displayed from the CRT display device 23. It is output (step B2). When the dot size of the output pattern to be created is selected and designated from the input designation device 14, the designated dot size is transferred to the cutout control unit 16 (step B3).

Next, in order to specify a registered pattern having the same size as the output pattern to be created this time and the letter face, the identification code is input from the input specifying device 14 (step B4).
Then, the registered pattern corresponding to the input identification code is read out from the font file memory 21 and taken into the font file reading buffer 26 (step
B5). Then, the output size analysis unit 27 analyzes the letter face size B of the registered pattern (step B6). In this case, after determining the letter face size by the number of dots,
The number of dots is converted to a unit of mm.

Letter face size Bmm obtained in this way
, The same processes as those in steps A5 to A9 in FIG. 3 are sequentially executed (steps B7 to B11). Therefore, an output pattern having the same letter face size as the registered pattern can be created by simply designating the already created registered pattern without inputting the letter face size from the input specifying device 14. In particular, logos and marks generally consist of multiple characters, etc. In such a case, if the letter face size is entered for the first character, the output pattern for the second and subsequent characters must be created with the same size. As a result, it is possible to prevent a problem caused by a delicate mismatch between letter face sizes.

In the above embodiment, the letter face size is input, but a box size may be input.

[Effects of the Invention] According to the present invention, when an arbitrary portion of an image is printed out at a designated size, the print output size can be easily designated using a pre-registered image, and
Since it becomes possible to specify the desired image portion while checking the output size, a print image of the desired size can be obtained according to the image of the user with a simple operation.
