FIG. 2 is a flow chart for explaining the earth observation satellite image scroll display method using the apparatus shown in FIG.

First, in the color allocating means 21 in the central processing unit 20, the three wavelength bands displayed in red, green and blue are read from the input device 10 and stored in the wavelength band color storage section 31 (step S1). .

Next, the color number table creating means 22 in the central processing unit 20 creates a color number table by assigning a color number to each color and stores it in the color number table storage unit 32 (step S2). . Here, by dividing the lightnesses of red, green, and blue into N gradations respectively, N × N × N kinds of colors can be created, and the color number table shows N × N × N kinds of color numbers. It is attached.

Next, in the mission data input means 23 in the central processing unit 20, the mission data storage unit 3
It is checked whether or not the data to be displayed next is present in 3 (step S3). If it is detected that the data is present, one line of data is extracted from the mission data storage unit 33, and the data is extracted. It is stored in the line data storage unit 34 (step S4).

If it is detected in step S3 that no data exists in the mission data storage unit 33, the process ends.

Next, in the image data creating means 24 in the central processing unit 20, the data stored in the line data storage section 34 is read out, and the wavelength band and the color number table stored in the wavelength band color storage section 31 are stored. With reference to the color number stored in the unit 32, the data read from the line data storage unit 34 is converted into a color number to create image data, which is stored in the last line of the image data storage unit 35 (step S5).

Next, the image data display means 25 in the central processing unit 20 reads out the image data stored in the image data storage unit 35 and displays it through the output device 40 (step S6).

Thereafter, in the scroll means 26 in the central processing unit 20, the line for reading the data from the image data storage unit 35 is forwarded by one line (step S

After the image data is displayed through the output device 40 in step S16, the command processing means 27 checks whether or not a command is input through the input device 10 (step S17).

If it is detected in step S17 that an instruction has been input, the type of instruction is checked (step S18). If the instruction is "stop", the current image is displayed until the next instruction is input. If it is displayed (step S19) and the command is "continue", the scroll means 26 sends the line for reading the data from the image data storage unit 35 one line before (step S20), and the command is " If it is “Cancel”, the process is terminated.

If it is detected in step S17 that no command has been input, step S20.
The process shifts to.

In step S20, the scroll means 26 sends the line for reading the data from the image data storage unit 35 one line before, and then the process returns to step S13.

The operation corresponding to the input instruction among the series of operations described above will be specifically described below.

FIG. 6 is a diagram for specifically explaining the operation for the input instruction among the operations shown in FIG.

While the processes of steps S13 to S17 are being repeated, the image is scroll-displayed via the output device 40.

Here, when it is detected in step S17 that an instruction is input through the input device 10 and it is determined in step S18 that the instruction is a "stop" instruction, the process proceeds to step S19, and the next step is performed. Waits for the input of command.

In this state, when a new command is input and it is determined in step S18 that the command is the "continue" command, the process proceeds to step S20 and the image scroll display is performed again.

In the middle of the display, it is detected in step S17 that an instruction is input through the input device 10,
If it is determined in step S18 that the instruction is the "stop" instruction, the process ends.

As described above, in this embodiment, the image can be stopped during the image scroll display, and the process can be stopped during the image display.
