Abstract

PURPOSE:To display images on a CRT display device at the same scale independently of longitudinal and lateral images by providing the image processor with a control means for displaying a longitudinal image or a lateral image on an approximately square display area without changing the scale. CONSTITUTION:When a CPU specifies a writing address by using an address control circuit 44a in a display control part 44, a longitudinal image supplied from a page memory 40 is stored in a storage area 42a corresponding to a display area for displaying a longitudinal original processing image stored in a display memory 42. On the other hand, a lateral image is displayed in a storage area 42b corresponding to a lateral image display area stored in the memory 42. Since the longitudinal image or lateral image can be displayed on a CRT display device having an approximately square display area without changing the scale, these images can be displayed on one CRT display device at the same scale independently of longitudinal and lateral images.

By scanning the document (document) two-dimensionally with a laser beam, an electrical signal corresponding to the image on the document is obtained.

The optical disk device 22 sequentially stores images read by the scanner device 18 on the optical disk 20 .

It also searches the optical disc 20 for an image corresponding to specified search information specified using the keyboard 23' or the like.

The keyboard 23 is used to input unique search information corresponding to the image to be stored on the optical disc 20 and various operation commands such as storage, search, and editing processing.

Further, the mouse 29 can be used, for example, by arbitrarily moving a cursor (not shown) displayed on the display window 24a on the CRT display device 24 up and down, left and right, and in directions, and by giving an instruction at a desired position. This is for selecting or instructing the display contents (various operation modes, area designation for edited images, icons, etc.) where is located.

The CRT display device (cathode ray tube display device) 24 is
Images read by the scanner device 18 and the optical disc 2
It is a rectangular image that displays images searched from 0. Icons and the like are displayed at the top, bottom, and right end of a display window (a rectangular or substantially square display area) 24a of the CRT display device 24, and a square portion at the center of the screen becomes a display area for displaying images. In this display area A, a vertically long image or a horizontally long image is displayed. As a result, if the original processed image is a vertically long image, it is displayed vertically, and if the original processed image is a horizontally long image, it is displayed horizontally. For example, as shown in FIGS. 4 and 5, a vertically long original processed image is displayed in display area a, and a horizontally long original processed image is displayed in display area b.

Further, the display window 24a of the CRT display device 24 is a multi-window type display device that can display four images simultaneously using a maximum of four windows (not shown).

Editing processes such as enlarging, reducing, rotating, scrolling, etc. are performed on the images displayed in each display window independently.

The magnetic disk device 27 stores various control programs on a magnetic disk 28 attached to the magnetic disk device 27, and also has an optical disk 20 that stores search information input from the keyboard 23 and images corresponding to this search information. It stores search data consisting of the above storage address, image size, etc.

Regarding the rotation of the image in the display memory 42, the first
This will be explained using the configuration diagram of the main parts shown in the figure.

That is, the vertically long original processed image retrieved and read from the optical disc 20 is first stored in the page memory 40. The vertically long image stored in the page memory 40 is output to the display memory 42. At this time, the CPU 34 specifies the write address using the address control circuit 44a of the display control unit 44, thereby allowing the CPU 34 to write to the display area a of the display memory 42.
The vertically long image supplied from the page memory 40 is stored in the storage area 42a corresponding to the page memory 40.

Further, the horizontally long vaporized image retrieved and read from the optical disc 20 is first stored in the page memory 40. The horizontally long image stored in this page memory 40 is stored in the display memory 42.
is output to. At this time, the CPU 34 controls the display control unit 44.
By specifying a write address using the address control circuit 44a, the horizontally long image supplied from the page memory 40 is stored in the storage area 42b corresponding to the display area b of the display memory 42.

Further, when rotating a vertically long image, the CPU 34 specifies a read address to the display control unit 44, and thereby the vertically long image information stored in the storage area 42a is output to the vertical/horizontal conversion circuit 48. This output vertically long image is converted into a horizontally long image by the vertical/horizontal conversion circuit 48 and output to the display memory 42. At this time, CP
By specifying a write address using the address control circuit 44a of the display control unit 44, the U34 writes data into the storage area 42b corresponding to the display area b of the display memory 42.
- The horizontally long image supplied from the vertical/horizontal conversion circuit 48 is stored.

Further, when rotating a horizontally long image, the horizontally long image information stored in the storage area 42b is outputted to the vertical/horizontal conversion circuit 48 by designating a read address from the CPU 34 to the display control unit 44. This output horizontally long image is converted into a vertically long image by the vertical/horizontal conversion circuit 48 and output to the display memory 42. At this time, CP

Next, a search process for images stored on the optical disc 20 will be described. First, set the search mode using the keyboard 23 and select the image you want to search.1. Enter search information. The CPU 34 sequentially compares and collates the input search information with the search information stored on the magnetic disk 26, and sequentially checks whether or not search information that matches the input search information is stored. And C.P.
In U34, a logical address corresponding to search information that matches the input search information is read out.

The CPU 34 calculates a physical track address and a physical sector address corresponding to this address, and uses these addresses to cause the optical disc device 22 to reproduce images from the optical disc 20. The CPU 34 also controls the optical disk device 2.
Image per scanning line supplied from 2 (compressed information)
is supplied to the compression/expansion circuit 50, subjected to band expansion processing, and sequentially supplied to the page memory 40. This page memory 40
The image stored in is output to the display memory 42. As a result, if the above-mentioned image is a vertically long image, the display memory 42
The above image is stored in the storage area 42a corresponding to the display area a. Therefore, the display control section 44 displays the contents stored in the storage area 42a of the display memory 42 on the display area a of the CRT display device 24. In addition, if the above image is a horizontally long image, the display area b1 of the display memory 42
;The above image is stored in the corresponding storage area 42b.

Therefore, the display control unit 44 displays the contents stored in the storage area 42b of the display memory 42 on the display area b of the CRT display device 24.

Also, a case will be described in which rotation processing is instructed for the image for which the above search has been performed. That is, when rotating a vertically long image into a horizontally long image, the CPU 34 specifies a read address to the display control unit 44, so that the vertically long image information stored in the storage area 42a is output to the vertical/horizontal conversion circuit 48. Ru. This outputted vertically long image is converted into a horizontally long image by the vertical/horizontal conversion circuit 48, and is then converted to a horizontally long image by the display memory 42.
is output to. At this time, the CPU 34 controls the display control unit 44.
By specifying a write address using the address control circuit 44a, the horizontally long image power (shape) supplied from the vertical/horizontal conversion circuit 48 is stored in the storage area 42b corresponding to the display area b of the display memory 42.

Further, when rotating a horizontally long image, the horizontally long image information stored in the storage area 42b is outputted to the vertical/horizontal conversion circuit 48 by designating a read address from the CPU 34 to the display control unit 44. This output horizontally long image is converted into a vertically long image by the vertical/horizontal conversion circuit 48 and output to the display memory 42. At this time, CP
By specifying a write address using the address control circuit 44a of the display control unit 44, U34 writes the vertically long image supplied from the two-legged vertical/horizontal conversion circuit 48 to the storage area 42a corresponding to the display area a of the display memory 42. is memorized.

” - As mentioned above, since a vertically long image or a horizontally long image is displayed without changing the scale on a CRT display device that has an approximately square display area, the displayed image is vertically long or horizontally long. Regardless of the size, it can be displayed on a single CRT display device and at the same scale.

Furthermore, a rectangular display is used as the CRT display device, and when a vertically long image or a horizontally long image is displayed on the display, the gap of 1:11° can be effectively utilized.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide an image processing device that can display an image with one display element of 0 stages and at the same scale, regardless of whether the image is vertically long or horizontally long.
