Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a still image transmission system.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a still image transmission system for transmitting still image data between still image transmission devices. The still image transmission device includes a portable type and a stationary type. A file device such as a magneto-optical disk device is connected to the stationary still image transmission device. For example, still image data is transmitted from a portable still image transmission device to a stationary still image transmission device via a telephone line.

[0003]

However, the conventional portable still image transmission device cannot communicate with the stationary still image transmission device, and, for example, a still image file recorded on a magneto-optical disk cannot be transferred over the telephone line. It was also impossible to receive over.

On the other hand, it has been possible to receive a desired still picture file between the stationary still picture transmission apparatuses by typing in the file name with the attached keyboard.

However, since it does not have a function of retaining the history of received still image files, the file names of previously received still image files cannot be confirmed, and still image files received in the past can be simply received again. I couldn't.

In addition, when a plurality of still image files are continuously received and the contents of the images are viewed to find a desired still image file, the file name is forgotten but the file name is forgotten. If it happened, I could not know the file name.

Therefore, the present invention provides a still image transmission system capable of holding the history of received still image files.

[0008]

The present invention provides a still image transmission system configured to transmit still image data between a first still image transmission device and a second still image transmission device. Of the still image transmission device includes a file device for storing a plurality of still image files each having a file name, and the first still image transmission device reads the still image file from the file device via the second still image transmission device. A storage means is provided for storing the file name of the image file from the latest file name to the file name traced back by a predetermined number.

[0009]

The file name is stored in the storage means each time a still image file is read from the file device by the first still image transmission device via the second still image transmission device. In other words, the storage means stores the file names of the received still image files, which are traced back a predetermined number from the latest file name. for that reason,
You can easily check the file name of the still image file received in the past.

The oldest file name stored in is displayed on the display 12 (see FIG. 20B). And "6"
Alternatively, each time the "9" key is pressed, a new file name of the reception order is displayed.

On the other hand, if the "4" or "7" key is pressed while the file name with "FILE" added is displayed on the display unit 12, the newest one stored in the work RAM 104 is displayed. File name is display 1
It is displayed in 2. Then, every time the key "4" or "7" is pressed, the file name in the old reception order is displayed.

In this case, "HIST" is added to the file name and displayed, and the numbers given from [1] are displayed in the oldest order. When the number of received still image files is less than 10, the total number of received files can be known from this number.

By pressing the "5" key, the display on the display 12 can be returned to the state in which the file name with "FILE" is displayed (FIG. 20A).
reference).

In the transmission apparatus 1 of this example, as described above, any one of the file names of the still image files received in the past can be displayed on the display unit 12 and the still image file can be received again.

FIG. 21 shows the operation on the transmission device 1 side when the file name of a still image file received in the past is displayed on the display unit 12 and the still image file is requested again.

First, as described above, the "4", "7", "6", and "9" keys of the number keys 14 are used to re-receive one of the still image files previously received on the display unit 12. The file name of the desired still image file is displayed (step 195).

Next, the function key 13 is used to request a still image file (step 196). In this case, the rightmost key of the function keys 13 is sequentially pressed to display "GE" on the display 12.
"T" is displayed (see FIG. 20B). When the key corresponding to “GET” of the function key 13 is pressed in this state, the CPU 101 of the transmission device 1 causes the system bus 10
2. A still image file request is transmitted to the transmission device 2 via the internal modem 111. This still image file request relates to the still image file having the file name displayed on the display unit 12 in step 195.

The following steps are the same as the corresponding steps in FIG. 11, and in the end, the transmission device 1 receives from the transmission device 2 the still image file having the file name displayed on the display unit 12, and the still image file is used to stop the still image file. Image is monitor 1c
Is displayed in.

Since the operation on the transmission device 2 side is the same as that shown in FIG. 12, description thereof will be omitted.

As described above, in the present example, using the numeral keys 14 of the transmission device 1, "4", "7", "6", and "9" are used to receive the data on the display 12 of the transmission device 1 in the past. The file name of the created still image file can be displayed. As a result, the transmission device 1 can simply and again receive the still image file received in the past with reference to the display on the display 12.

At this time, since the file names are displayed on the display unit 12 in order from the oldest received number and the file names are displayed, the receiving order of the still image files received in the past can be known. Therefore, for example, when receiving a plurality of still image files in succession and looking at the image contents to search for the desired still image file, I remember the number, but forget the file name. In this case, the file name can be easily confirmed by referring to the display on the display unit 12.

Further, by making a still image file request using the function key 13 while displaying any of the file names of the still image files received in the past on the display device 12 of the transmission device 1, the still image file is requested. Image files can be received. That is, the still image file received in the past can be received again by a simple key operation.

In the above-described embodiment, the work RAM 104 is used.
Although only 10 file names are stored in, the maximum number can be made suitable for the usage environment of the device.

Further, in the above embodiment, the file device connected to the stationary still image transmission device 2 is the magneto-optical disk device 4, but it may be another file device such as an optical disk device or a magnetic disk device. The present invention can be similarly applied.

Further, in the above-mentioned embodiment, the still picture transmission system in which the portable still picture transmission apparatus 1 and the stationary still picture transmission apparatus 2 are connected by the telephone line 5 is shown. It is needless to say that the present invention can be similarly applied to the still image transmission system in which the stationary type still image transmission devices are connected.

[0120]

According to the present invention, since the storage means of the first still image transmission device stores the file names of the received still image files from the latest one up to a predetermined number, the received still image file is received in the past. The file name of the created still image file can be easily confirmed, and the usability of the first still image transmission device can be greatly improved.
