Thus, the deterioration of the picture quality of the parts picture can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an information processing device capable of processing, for example, binary images and gradation images.

(Prior Art) In this type of 41 information processing device, when image information is read by an input device such as a scanner device, it is possible to read it as a binary image or a gradation image such as a dither image. .

By the way, when cutting out part of the image information read in this way and processing this image information as a part image, the attributes of this part image are set to the original image information before cutting. Processed by attributes. For example, reading image information consisting of a photo and text as a binary image,
When a part of the photograph is cut out from this image information to form a part image, this part image is processed as a binary image. Conversely, if image information consisting of a photograph and text is read as a dithered image, and the text portion is cut out from this image information to create a component image, this component image will be processed as a dithered image.

Conventionally, the attributes of a component image depend on the attributes of the image from which it is extracted, so the attributes of the component image and the processing attributes may differ, and when the component image is displayed on a display device, the image quality may vary. sometimes deteriorated.

(Problems to be Solved by the Invention) This invention solves the problem that image quality deteriorates when image processing is performed on created component images because image attribute information is not managed.

It is assumed that image information consisting of a photographic image P and a character image CA is displayed on the screen of the CRT display device 26, as shown in FIG. When generating a component image from the displayed image information, first, point to "Menu 1" with cursor C, and move cursor C downward in the figure while pressing the first button of mouse 14. Then,
As shown in FIG. 4, the contents of "Menu 1" are displayed.

In this state, after instructing cutting with the cursor C, if you specify a point Sa located near the photo image P and a point sb, a rectangular frame S with these points Sa and Sb as diagonal points will be displayed. The image information within this frame S is cut out as a component image (step 5TI).

Thereafter, when the cursor C is moved downward in the drawing while holding down the first button while pointing to "Menu 2" with the cursor C, the contents of the "Menu 2" are displayed as shown in FIG. Then, use cursor C to specify "component attribute". After this, image information that specifies part attributes,
That is, when a portion of the created component image is pointed with the cursor C, a property sheet for specifying component attributes as shown in FIG. 6 is displayed. In this state, if you point to "Photo" with cursor C and press the first button, the attribute information of this part image will be stored as a dithered image (
Step 5T2).

That is, the magnetic disk device 19 is provided with a parts management table PMT as shown in FIG. 7, and when a part image is created as described above, a part number is set in the part image. Then, when attribute information is set for this part image, the attribute information of the part image is stored in correspondence with the part number.

This attribute information is retained unless changed.

Also, if you want to change the attribute information of a component image, use cursor C to select "Component Attribute" from "Menu 2" as described above.
In addition to specifying the component image whose attribute information is to be changed, the property sheet is displayed. By specifying required attribute information in this property sheet, the attribute information of the component in the component management table PMT shown in FIG. 7 is changed (step ST3.4).

-Furthermore, when developing a component image with attribute information set as described above from the page memory 21 onto the display memory 22a, the component number and attribute information attached to this component image are extracted from the component management table PMT. is read out and supplied to the image processing circuit 34. In this image processing circuit 34, the component image is converted according to this information and expanded from the page memory 21 onto the display memory 22a. That is,
For example, if a binary image is a component image and attribute information of a dither image is set to this component image, the image processing circuit 3
At step 4, as shown in FIG. 8, the binary image read from the page memory 21 is converted into a dither image using a dither matrix, and the dither image is developed in the display memory 22a.

Further, if binary image attribute information is set for the dithered image, the dithered image is converted into a binary image and developed in the display memory 22a (step 5T5).

According to the embodiment described above, attribute information is managed corresponding to a component image, and when displaying a component image, this attribute information is referred to for processing.

Therefore, it is possible to prevent a component image stored as a binary image from being processed as a dithered image or vice versa, thereby preventing deterioration in the image quality of the component image. It is.
