DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. In FIG. 1, the image data to be presented is personal computer 11
It is supposed to be generated by the word processor 12 or the like. The image data generated by the personal computer 11 or the word processor 12 is supplied to the data recording device 13. The data recording device 13 takes in the image data via the interface circuit 14,
The data is compressed in the data compression circuit 15 and then stored in the data storage circuit 16. As the data storage circuit 16, for example, a memory card having a semiconductor memory built in a card-shaped case is used.

On the other hand, the image data stored in the data storage circuit 16 is read by the data reproducing device 17. The data reproducing device 17 has, for example, a remote control function using infrared rays, and its operation is controlled by operating the remote control operating unit 18. That is, when the remote control operating unit 18 gives an operation instruction to the image data to be displayed, the instruction data is supplied to the instruction control circuit 19. The instruction control circuit 19 controls the data reading circuit 20 so as to read the instructed image data from the data storage circuit 16.

The image data read by the data read circuit 20 is expanded by the data expansion circuit 21, and
A switching circuit 22 that performs a switching operation under the control of the instruction control circuit 19 outputs the image to one of the two image output circuits 23 and 24. In this case, the switching control of the switching circuit 22 by the instruction control circuit 19 is based on the content instructed by the remote control operation unit 18. Then, the image output circuit 23 or 24 to which the image data is guided converts the input image data into, for example, a signal form that can be image-displayed by a monitor (not shown) and outputs the signal to the monitor. The image data instructed by is displayed on the desired monitor and a presentation is given.

Further, a series of operation instruction procedures as described above can be stored in the instruction storage circuit 25 via the instruction control circuit 19. Then, according to the operation instruction stored in the instruction storage circuit 25, the instruction control circuit 19 reads out the image data from the data storage circuit 16 and selects the image output circuits 23 and 24, thereby automatically executing the presentation. Can be made.

FIG. 2 shows the details of the remote control operating section 18. In other words, the remote control operation unit 18 includes "automatic", "learning", and "STOP" key groups for giving instructions regarding automatic execution, and "MAIN", "keys" for giving instructions regarding output monitor switching. SUB ”and“ BOTH ”key groups,“ 1 ”,“ 2 ”to“ 0 ”numeric keys that can directly specify the image data number to be displayed, and the currently displayed image Key groups of "<<" and ">>" for designating images before and after and a PAUSE key for temporarily stopping the operation in the automatic execution state.

FIG. 3 is a flow chart showing the operation of the data reproducing device 17 using such a remote control operating section 18. First, when the operation is started (step S1), the instruction control circuit 19 enters a state of waiting for an instruction input from the remote control operation unit 18 in step S2.
Then, when an instruction is input from the remote control operation unit 18, the instruction control circuit 19 first sets in step S3.
Then, it is determined whether or not the input instruction is the image data number operated by the ten keys. If the image data number (YES),
In step S4, the instruction control circuit 19 reads out the image data of the instructed number from the data storage circuit 16 and operates to display the image on the currently selected monitor.

After that, the instruction control circuit 19 proceeds to step S
In step 5, an operation instruction procedure is executed for automatic execution.
5, it is determined whether or not learning for accumulation is being performed. If learning is not in progress (NO), the process returns to step S2, and if learning is in progress (YES), the operation instruction is stored in step S6. After storing in the circuit 25, the process is returned to the step S2.

If it is determined in step S3 that it is not the image data number (NO), the instruction control circuit 19 displays the input instruction at present by operating the respective keys "<<" and ">>" in step S7. It is determined whether or not the instruction is for designating images before and after the current image. Then, if it is a front and rear image display instruction (YES), the instruction control circuit 19 calculates the image data numbers before and after the instruction by the key from the latest designated image in step S8, and uses them for the processing in step S4. .. Thereby, the image data before and after the latest designated image currently displayed can be displayed.

Further, if it is determined in step S7 that the display is not the front / rear display (NO), the instruction control circuit 19 determines that the input instruction is "MAIN", "SUB", or the like in step S9.
It is determined whether or not there is an instruction to switch the output monitor by each key of "BOTH". If it is a switching instruction (Y
ES), the instruction control circuit 19 controls the switching circuit 22 so that the output from the data expansion circuit 21 is led to the designated monitor in step S10, and then causes the processing of step S5.

If it is determined in step S9 that it is not the output monitor switching instruction (NO), the instruction control circuit 19 determines in step S11 whether the input instruction is a learning instruction for automatic execution by the "learn" key. Determine whether. If it is a learning instruction (YES), the instruction control circuit 19
In step S12, the stored contents of the instruction storage circuit 25 are initialized, and thereafter, a learning operation for accumulating the input instruction in the instruction storage circuit 25 is performed, and then the process returns to step S2.

Further, when it is determined in step S11 that the instruction is not the learning instruction (NO), the instruction control circuit 19 determines in step S13 whether or not the input instruction is the instruction to end the learning operation by the "STOP" key. Then, if the instruction is an end instruction (YES), the instruction control circuit 19 determines in step S1.
After the learning operation is completed in step 4, the process returns to step S2. Further, it is not an end instruction in step S13 (N
If it is determined to be O), the instruction control circuit 19 determines in step S15 whether or not the input instruction is an automatic execution instruction by the "automatic" key. If it is an automatic execution instruction (Y
ES), the instruction control circuit 19 returns to the processing of step S2 after performing the automatic execution operation in step S16.

FIG. 4 is a flow chart showing the operation of this automatic execution. First, when started (step S17), the instruction control circuit 19 determines in step S18 whether or not there is an instruction input other than automatic execution (NO).
In step S19, it is determined whether or not there is an instruction in the instruction storage circuit 25, and if there is (YES), in step S20, an automatic execution operation is performed based on the instruction of the instruction storage circuit 25,
The process returns to step S2.

If it is determined in step S18 that there is an instruction input other than automatic execution (YES), the instruction control circuit 19 determines in step S21 whether the instruction is an end instruction, which is the end instruction ( If YES, the automatic execution operation is ended in step S22. If it is determined in step S19 that there is no instruction in the instruction storage circuit 25 (YE
Also in S), the instruction control circuit 19 ends the automatic execution operation in step S22.

Further, if it is determined in step S21 that it is not the end instruction (NO), the instruction control circuit 19
In step S23, it is determined whether or not it is a temporary stop instruction of the automatic execution operation by the "PAUSE" key, and if it is not a temporary stop instruction (NO), the process returns to step S18.
If the instruction is a pause instruction (YES), the instruction control circuit 19 determines in step S24 whether or not there is an instruction input other than automatic execution. If not (NO), the determination process is continued. If (YES), in step S25, it is determined whether or not there is an end instruction, and if it is an end instruction (YES), the automatic execution operation is ended in step S22.

If it is determined in step S25 that the instruction is an end instruction (YES), the instruction control circuit 19 determines in step S26 whether the instruction is a temporary stop instruction of the automatic execution operation by the "PAUSE" key. If it is not a pause instruction (NO), the process returns to step S24, and if it is a pause instruction (YES), the process returns to step S18.

Therefore, according to the configuration of the above embodiment, the image data to be presented is stored in the data storage circuit 16 in advance, and the desired image data can be displayed on the arbitrary monitor by the operation of the remote control operation unit 18. Since the image is selected and displayed, the handling becomes very convenient, and the workability for switching the screen and the visibility of the screen can be improved. Further, by providing the automatic execution function, the presentation can be performed more easily.

Further, flag data indicating whether to display a parent screen or a child screen at the time of displaying an image is added to each image data and stored in the data storage circuit 16, and when reproduced by the data reproducing device 17, It is also possible to identify the flag data and display the parent screen or the child screen on the monitor screen. The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.
