It has a function of holding the data at that point in time when the shutter is released. It also has a function of sending various monitor commands that the television camera manual device 68 has.

With such a configuration, the multivalued WS has two values for the multivalued image.
It can realize the same function as value WS, and can include and process binary images if necessary.

In order to distinguish between binary image data and multi-valued image data as described above, and to identify transfer between various devices,

According to this, a 2M4 image or a multivalued image is stored in 50.

Next, the operation of the above embodiment is shown in FIG. 12 (1).

This will be explained according to the document editing flow shown in (2).

First, in step S1, a binary image from a binary RD, a multivalued image from a multivalued RD, text, figures, tables, graphs, binary images, multivalued images stored in the HD, and a camera or VTR are extracted. A multivalued image of the integrated document or a blank sheet of paper is selected and displayed. Next, in step S2, the process branches to the following process depending on the type of these displayed documents and the specified command. The processing includes print processing s4, document input editing S6. Shape editing S
8. Table editing SIO.

Graph creation S12, binary image editing s15, multivalued image editing S16. There is data extraction S22 and data synthesis S24.

If binary/multi-value conversion is specified for a binary image, the binary image is converted into a multi-value image in step S16, and the process proceeds to step 319, where the multi-value image is converted to 18%.

If multivalue/binary conversion is specified for a multivalued image, the multivalued image is converted into a binary image in step 320, and the process proceeds to binary image editing in step S15.

Binary image editing allows you to cut out figures, characters, etc., enlarge or reduce the cut parts, rotate them, move them, and roughly combine them. In addition to these functions, multi-level image editing also allows for gradation conversion, edge enhancement, object cropping, etc.

When the document editing is completed in S25, the document is written out in step 326, printed out, displayed, saved on a hard disk, etc., and the flow ends.

In the image processing system configured as described above, the multivalued WS7-1.7-2. ..., 8-1°8-2.・・・
In . . , a document such as the one shown in FIG. 13 can be displayed and edited. Here, 60 is an integrated document, which includes a document 612, a figure 62, a graph 631, a table 66, a multivalued image 64 such as a photograph, and a binary image 65 such as a figure.

Reference numeral 67 is a display area for instructing different editing commands depending on the editing state.

Here, text 611, figure 62. The graph 63 and the table 66 are bit-expanded from the code data to the binary BUF 52 in FIG. 8, and the binary image 65 is thinned out and transferred to the same binary BUF 52 by the scaling function of the BMU 18 in FIG. There is.

In addition, the multi-value image 61 is stored in the multi-value BUF 53 in FIG.
The images are transferred by the function of the MU 18, and are superimposed and displayed on the CRT 16 in FIG.

Furthermore, the input from the television camera in step S1 is performed using a display as shown in FIG. That is, for example, when the integrated document 6o is displayed, the monitor screen 73 is displayed above it.

This is realized by repeatedly writing human power from the television camera input device 68 into the portion of the multivalued BUF 53 corresponding to the monitor screen. A command group 74 is displayed in order to remotely control this television camera input device 68 in the multivalue W S 8-2. The displayed contents are as shown in FIG. 15, for example, and the following commands are displayed: brightness, contrast, focus, zoom, aperture, shutter, and UP-DOWN-LEFT-RIGHT for the tilt base of the television camera.

Here, when the brightness/contrast is specified, its value is sent to the television camera input device 68.

Also, regarding focus, zoom, and aperture, the corresponding values are FAR, NEAR, and E.

While the WIDE, 0PEN, and CLO5E (7) portions continue to be specified, the commands are continued to be sent and adjusted.

The same applies to UP, DOWN, LEFT, and RIGHT.

When the shutter is designated, the monitor is stopped and the data of the multi-valued BUF 53 at that time is determined as manual data.

The following is subject to editing as a multivalued image as described above.

In the above embodiment, an image processing system connected via a network is used, but the present invention is not limited to this, and a part of the system may be omitted or a part may be changed.
It goes without saying that the present invention can also be implemented within one device.
