Abstract

PURPOSE:To overlap an objective segmented picture with the picture information of a synthesis source with an easy operation by scrolling picture information sythesized by picture density which differs at the inside and outside of frames set inside picture information to be the synthesis source. CONSTITUTION:Picture information 34 to be synthesized, is read out in the prescribed area of a RAM 3 and a density change area 35 is secured in parallel to the designation of an area 33. A CRT control part 16 executes a dither- processing which changes the density at the inside and outside of the density change area 35. A segmenting frame 43 and picture information 34 to be synthesized whose density is changed and processed are displayed on a display device 8, and they are scroll-operated. Said information 34 is shifted and the picture to be segmented is secured on the stub frame 43. When a keyboard 9a or the like instructs the end of the synthesis, picture data excepting that which is settled in the density change area 35 is erased among synthesized picture information 34, and synthesized picture information 44 is displayed on the display device 8.

[Detailed Description of the Invention] [Industrial Application Field] This invention registers image information input from an image reading means in seven image information storage stages, reads out the registered image information to a display device, and displays the image. The present invention relates to an image processing device that performs processing.

[Conventional technology]

In recent years, advances in the technology of information processing devices such as word processors and image processors have been remarkable, and in particular, when editing graphics in documents, it is now possible to cut out other documents or graphic information and add that information to the original information. It has become.

FIGS. 6(a) to 6(c) are schematic diagrams illustrating a conventional image information synthesis operation.

In FIG. 4A, 41 is image information, which is composed of katakana, numbers, alphabets, and the like. Same figure (b)
, reference numeral 42 denotes image information, which is composed of figures and the like, and shows a state in which a desired area of the image information 42 is designated by a cutting frame 43. In FIG. 4(C), numeral 44 indicates composite image information, which shows the state in which the image information within the area cut out by the cutting frame 43 is combined with the image information 4 shown in FIG. 4(a).

Conventionally, a part of the image information 42 shown in FIG. 4B, that is, the image information within the cutting frame 43, is synthesized with the image information 41 shown in FIG. In order to obtain the information 44, first, the image information 42 is displayed on a display (not shown), the cropping frame 43 is designated, and the image information within the cropping frame 43 is stored in a predetermined storage area. Image information 41 is displayed on the display, and a frame 45 of the same size as the cutting frame 43 set for the image information 42 is displayed.
, move the frame 45 to the desired position,
When the positioning is completed, the stored image information in the cutout frame 43 is transferred to the area secured by the frame 45 to obtain composite image information 44 as shown in FIG. 4(c).

[Problem that the invention seeks to solve]

Therefore, if the operator is not satisfied with the image information cut out from the image information 42 to be synthesized using the cropping frame 43 and synthesized with the image information 41 that is the source of synthesis, the operator must repeat the above operation several times. There were always opening points that required complicated operations. All of these problems are caused by the inability to determine accurate trimming positions because the cutting operation and the compositing operation must be performed independently.

This invention was made in order to solve the above problems, and it is possible to freely scroll the image information to be synthesized with different image densities inside and outside the frame set in the image information to be the synthesis source. It is an object of the present invention to provide an image processing device that can superimpose a desired cut image on image information of a composition source with a simple operation.

[L stage for solving problems]

The image processing device according to the present invention includes a first data processing unit that saves image information of an area corresponding to a cropping frame from among image information developed as a compositing source in a display memory;
A predetermined density conversion process is performed on the image information to be synthesized read from the image information storage stage f so that the inside and outside of the area corresponding to the data-processed cropping frame have different densities by the first data processing means. The second data processing means is provided with a second data processing means for performing image processing, and a developing means for synthesizing and developing image information whose density has been converted by the second data processing means into a display memory.

[Effect]

In this invention, the first data processing means saves the image information of the area corresponding to the cropping frame from among the image information developed as a compositing source in the display memory, and the second data processing means saves the image information of the area corresponding to the cropping frame. A predetermined density conversion process is performed on the image information to be synthesized read out from the stage so that the density inside the area corresponding to the cropping frame data-processed by the first data processing means is different from the density outside the area. A developing means synthesizes and develops the converted image information in a display memory.
