Abstract

PURPOSE:To enable the picture editing machining with few operations by setting an operation mode by judging which area of the plural areas of a digitizer pad the pressure point showed by a coordinate signal belongs to. CONSTITUTION:When the data showing a coordinate value is in the coordinate range of an area key, whether the data showing the coordinate value is inputted as the coordinate of the area where an editing machining is performed or as the information of the area key is judged by a coordinate input flag. When the input of the coordinate of the area where the editing machining is performed is necessary, the coordinate input flag is turned ON. For instance, when the area machining & color conversion key of a digitizer pad 51 is pushed down, the coordinate input flag is turned ON because the designation of an area where a color conversion is performed is necessary. By turning it ON, when the data showing the coordinate value from an editor is transmitted next, the data is inputted as the coordinate value for the area designation. Normally, the coordinate input flag is turned OFF and the coordinate value data from the editor becomes area key information.

The n value can be obtained. This is TBXmax, TB
The same applies to Ymin and TBYmax.

In step 5, X coordinate> TBXmin +
If the condition of the value of address (cnt-1) is satisfied, the process proceeds to step 7, and if not, the process proceeds to step 6.
In step 6, the variable counter cnt is incremented (+1), and the process returns to step 4 to check the next area key. In step 7, the value of the X coordinate is Xmax
It is checked whether it is smaller than the value of TBXmax + (cnt-1) address in the coordinate table, and X coordinate <TBXma
If the condition of the value of address x (cnt-1) is satisfied, the process proceeds to step 8, and if not, the process returns to step 6.

In step 8, it is checked whether the value of the Y coordinate is larger than the value of TBYmin + (cnt-1) in the Ymin coordinate table, and Y coordinate> TBYmin.
If the condition of the value of address + (cnt-1) is satisfied, the process proceeds to step 9, and if not, the process returns to step 6. In step 9, it is checked whether or not the Y coordinate value is smaller than the value of the Ymax coordinate table TBYmax + (cnt-1) address, and Y coordinate <TBYmax + (cnt
-1) Step 10 if the condition of the address value is satisfied
If not, return to step 6.

In step 10, the function corresponding to the count value of the variable counter cnt indicating the value of NO in Table 1 is turned on.
Is sent to the system control unit 93, and step 1
Go to 1. In step 11, it is checked whether the function turned on in step 10 requires coordinate designation. If necessary, the process proceeds to step 12 to turn on the coordinate input flag to end the processing, and if not necessary, Immediately end the processing.

Next, the digitizer pad 5 of the editor 50 is
The processing by the operation display control unit 92 when the area key for area designation & color conversion including the case where 1 is used for area designation and the case where it is used as an area key is pressed will be specifically described with reference to FIG. To do.

First, in step 21, it is checked according to the processing shown in FIG. 1 whether or not the area designation & color conversion area key has been pressed. The coordinate input flag is set to ON because it is necessary to specify the area by the processing, and thereafter, FIG.
When the processing of (1) is executed, the designated coordinate values are stored one after another until the area designation is completed. In step 22, the processing of FIG. 7 is executed, the coordinate values are stored as described above, and the area is designated.

In step 23, in order to specify the color of the specified area before conversion, it is checked by the process shown in FIG. 7 whether or not the color specifying area key is pressed. After that, the process proceeds to step 24, and the data indicating the designated color (before conversion) is sent to the system control unit 93. In step 25, in order to designate the color after conversion of the designated area, it is checked whether or not the area designation key is pressed by the processing of FIG. After that, the process proceeds to step 26, in which data indicating the designated color (after conversion) is sent to the system control unit 93,
The process ends.

As described above, in this embodiment, the digitizer pad 51 of the editor 50 is divided into a plurality of areas used as mode setting keys, and when the editor 50 generates a coordinate signal (data indicating coordinate values), The main body of the copying machine determines whether or not the coordinate input flag is in the ON state, and when the coordinate input flag is not in the ON state, determines which one of the above-mentioned areas the pressing point indicated by the coordinate signal from the editor 50 belongs to. Then, the copy mode (operation mode) is set according to the above determination results.

In addition, a mode in which the coordinate signal from the editor 50 is used as it is as a coordinate signal of the pressed point (first control mode) and a mode in which the copy mode is set according to the area of the pressed point of the digitizer pad 51 (first mode) 2 control mode) is switched to the state of the coordinate input flag (it is turned on by the operation signal from the operation display unit 60 or the area processing & color conversion key of the digitizer pad 51 is pressed).
According to. Therefore, the mode setting key having the same function as each of the above areas can be deleted from the operation display section of the copying machine main body. Further, it is possible to easily edit and process an image with a small number of operations.

[0064]

As described above, according to the present invention, since the editor can be used not only as the coordinate input means but also as the operation section for setting various operation modes, the operation section of the image forming apparatus can be used. It is possible to suppress the cost increase and easily edit and process an image with a few operations.
