To 9; the part of 0001 is written with the numbers of 0 to 9; and the part of jpg is jpg or crw. (3) The number represented by _0000 of CTG_0000 is set to A, and AUT_0001. The following equation (1) holds when the number represented by _0001 of jpg is set to B. The following 50 is the number of files allowed to be held in one CTG directory. A × 50 <B ≦ (A + 1) × 50 (1) The tag format that is not a camera standard is as follows.

<PRE><CR> CIFF_VERSION = 1.00 <CR> PWRSHOT_MULTI_ENTRIES <CR><IMG SRC ... In the above, PWRSHOT_MULTI_ENTR
The IES tag is a personal computer (P
Since C) indicates that editing has already been performed, it is immediately apparent that the camera must not edit. Therefore, in this case, it is not necessary to perform a complicated analysis as in the case of the tag.
Note that <CR> is a line feed code in Microsoft MS-DOS. The line feed code in Apple's Macintosh operating system is <LF> (line feed). When the device on the mounting side records, <CR> is recorded, but in the case of reproduction, even if a code represented by <LF> is given, the same operation is performed as the code represented by <CR>.

As described above, the transmission log is changed to CIFF (Ca
By creating and saving in a mark file format defined in “mera Image FileFormat”, transmission between a digital camera and a PC or the like that has received an image of the digital camera can be easily confirmed.

When the selection of the transmission image is completed, transmission can be performed. The destination registered by the address setting process in step S21 of FIG. 6 is displayed as shown in FIG. 7 (5), and can be selected from the displayed destinations. Of course, a configuration may be adopted in which a destination address or a telephone number is input at the time of transmission. During transmission, the transmission status is displayed as shown in (6). In this screen, [Can
cel] button is displayed, and transmission can be interrupted by specifying this button.

When the transmission is completed, a log file in the mark file format is automatically created regardless of whether the transmission is normally completed. If the transmission has been completed normally, the transmission mark file Selimage. mrk,
The log file created by the image transmission becomes the same. Note that the log file is automatically given a file name according to a certain rule. In the example shown in the directory structure of FIG. mrk, and “X” is given a number in the order of creation. In addition, ShowlogX. The format of mrk is Selima
ge. The format is the same as that of mrk, except that the storage target is the transmitted image.

Next, performed in step S22 of FIG.
The log confirmation processing after transmission is described.

When the log is confirmed after the transmission is completed, [Check L in the menu shown in FIG.
og] and [Start] on the screen of FIG. 8 (2). As a result, as shown in FIG.
g The file name is displayed. Also, the three mark files Showlog1, Showlog2, Showlo
g3 can be managed.
g It is possible to display an image for confirmation.

In the menu of FIG. 8C, when a log file to be viewed is selected, the transmitted first image is displayed. FIG. 8D shows a case where the 14th image is displayed when 30 images are transmitted in one communication. The numbers at the upper left of the screen indicate the total number of images and the number of the image being displayed. Normally, in a slide show in which images are continuously displayed, there are settings such as a setting of a reproduction time and a presence / absence of repetition. However, since an image is displayed for confirming a log of transmission, automatic reproduction is not performed. The image registered in the log file is manually designated and displayed by the [+] button and the [-] button. If transmission fails, “En” in FIG.
Instead of displaying “d Sending”, an error process described later is performed.

To delete the log file, overwrite it at the time of Send, or select [C
This is done by selecting [Lear Log].
If you select [Clear Log], [Start]
The log file name is displayed in the same way as
g Select whether to delete the file and delete it. Before the deletion, a screen for confirming the deletion is displayed as shown in FIG.

It is also possible to change the name of the log file. In this case, when [Name Log] is selected, the log file name is displayed as in the case of [Start]. When a log file whose name is to be changed is selected, a screen shown in FIG. 8 (6) is displayed, and the log file name, which has been changed from log1 to log3, can be changed using the keyboard.

Also, from the menu of FIG.
When [W Info] is selected, as shown in FIG. 8 (7), the simple transmission information stored in the Log can be browsed by text. At the time of transmission, it shall be the same as the mark file of the transmission log or saved in a text file in a file associated with the mark file, and the viewable information includes the total transmission file, the total transmission file size, the transmission start time , Etc. input at the time of transmission. Note that this is an example, and it is also possible to browse all data that can be stored at the time of transmission, such as the telephone number of the transmission destination.

FIG. 9 shows a process performed when any of the items shown in the screen of FIG. 8 (2) is designated.

First, in step S101, it is confirmed whether or not the number of mark files has reached the maximum number. The maximum number of mark files is the maximum number of files that can be held as a mark file, and is a preset number. If the maximum number has been reached, end processing is performed in step S102, and if not, it is checked in step S103 whether there is any unprocessed mark file.
If there is no file (NO in step S103), the process ends in step S102.

If it is determined in step S103 that there is an unprocessed mark file, step S107
Judge whether the header is appropriate (whether or not the header is present and the format conforms to the standard). If the header is not appropriate, it is considered that the mark file is created by a different device. Then, the process returns to step S101.

The determination in step S107 as to whether the header is appropriate and the determination in step S111 described later as to whether or not the IMG tag matches the standard format are performed by confirming the above check points. In other words, determine which files cannot be selected by the camera,
Processing to exclude from selection. Items excluded from selection of image display include those edited by the PC and those changed by the user.

When the header is appropriate (YE in S107)
In step S109, the counter value cnt for counting the maximum number of transmission images (100 in this embodiment) is set to cnt = 0 in step S109, and then cn is set in step S110.
It is checked whether t <100, and if not, the process returns to step S101.

If cnt <100, step S11
In step 1, it is checked whether the IMG tag is appropriate. If the IMG tag is not appropriate, it is regarded as a mark file created by a different device, and the process returns to step S101. When it is confirmed that the IMG tag matches the format of the above standard, the process proceeds to step S112, and the value of the counter cnt is set to c.
In step S113, it is determined whether or not the IMG tag still remains. If there is no tag, the process returns to step S110. If there is no remaining IMG tag, it is determined in step S114 that the mark file can be browsed, and a flag indicating that the mark file can be browsed is set.
It returns to step S101.

When the process is completed in step S102, the file name of the mark file in which the flag indicating that browsing is possible is displayed as shown in FIG. 8 (3).

By creating a mark file for printing in the same manner as creating a mark file (log1 to log3) for displaying an image for transmission confirmation,
The transmission log can be automatically printed. Due to the nature of automatic printing, it is fundamental that no operation is performed in the procedure before printing. Unlike displaying an image on the display unit, it is not possible to save multiple log files for printing. Absent.

As an example, after the transmission is completed, the Prt_log. mrk
File in the mark file format. The format is the transmission log when displaying the image on the display unit
It is exactly the same as the one. In addition, save the date and time of transmission start and Log itself in text format as the header of the file or mark file related to it,
The text may be printed out.
At this time, a method of printing thumbnail images as a list, such as INDEX print of APS, and a method of printing normal images are also available as options.

When the transmission is not terminated normally but terminated due to some abnormality, the log file ShowlogX. mrk and Selimmag
e. Unsent files can be picked up by comparing the mrk file paths. Regarding the unsent file, a new mark file Send_err. When the mrk is created under the dc97 {misc} of the CF similarly to other mark files, the following applications can be considered.

When the file transmission ends abnormally, a screen as shown in FIG.
Appears at 8. At that time, Showlog
X. mrk and Selimage. mrk, and automatically compares Send_err. It is assumed that mrk has been created.

Note that Send_err. The format of mrk is described in Selimage. Same as mrk, but
The difference is that the storage target is an image for which a transmission error has occurred.

The mark file Send_er is described below.
r. 10 set according to the format of mrk
An example in which the number image transmission has an error is shown below. As an example, the Tag format according to the camera standard is as follows. <CR> is used as a carriage return symbol for convenience of description.

<PRE><CR> CIFF_VERSION = 1.00 <CR><IMG SRC = ”./ CTG — 0000 / AUT
_0010. jpg "><CR> The top two lines of the above tag are the header. The checkpoint for determining whether the tag of each file of the mark file is correct is the same as the checkpoint of the above-described Selimage.mrk. Here, the description is omitted.

The Tag format which is not a camera standard is as follows.

<PRE><CR> CIFF_VERSION = 1.00 <CR> PWRSHOT_MULTI_ENTRIES <CR><IMG SRC ... In the above, PWRSHOT_MULTI_ENTR
The IES tag is a personal computer (P
Since C) indicates that the editing has already been performed, it is immediately understood that the camera does not need to edit. Therefore, in this case, it is not necessary to perform a complicated analysis as in the case of the tag.
<CR> is a line feed code in Microsoft's MS-DOS. The line feed code in Apple's Macintosh operating system is <LF> (line feed). When the device on the mounting side records, <CR> is recorded. In the case of reproduction, even when a code represented by <LF> is given, the same operation as the code represented by <CR> is performed.

Next, the processing after the end of image transmission will be described with reference to the flowchart of FIG.

When image transmission is completed, step S110
In step S1, it is determined whether the processing has ended in error or normal. If the processing has been completed normally (Yes in step S1101), step S110
The process ends at 1102. On the other hand, in the case of an error end, in step S1103, the message “Selimage. mrk and ShowlogX. The comparison of the image file name described in mrk is started. First, the counter i is initialized to 0 in step S1104, and the count is incremented by 1 in step S1105. Then, in step S1106, Seli
image. The name of the i-th image file to be transmitted described in mrk is Showlog. Check if it is also described in mrk.

If not described, it is determined that the i-th image could not be transmitted, and step S1107
Send_err. The image file name is described in mrk, and the process proceeds to step S1108. If it is described, it is determined that the i-th image has been transmitted, and the process proceeds to step S1108.

In step S1108, by comparing the counter value i with the number of image files to be transmitted, Sel
image. It is determined whether all the image files described in mrk have been compared. If all image files have not been compared, step S1105
And the counter i is incremented by one, so that step S1
The operation from step S1108 to step S1108
ge. This is repeated until the comparison is completed for all the image files described in mrk.

When the comparison of all image files is completed (Yes in step S1108), step S1109
Send_err. The process for creating the mrk ends.

Send_er created in this way
r. The mrk describes all unsent image file names, and can be used to process unsent images.

In step S1110, U shown in FIG.
It is determined whether or not “Send only unsent images” is selected from the options on the I screen, and if “Send only unsent images” is selected, if it is a normal image transmission, Seli
image. When transmission is performed based on mrk, the second
In the embodiment, the Send_er in step S1111
r. An untransmitted image is selected and transmitted using mrk. When the transmission is completed, it is determined again in step S1101 whether the processing has ended in an error or normal, and if an error has occurred, the above processing is repeated.

If "Send from the beginning" is selected in step S1112, as in the case of normal image transmission, in step S1113, Image. mrk
, The transmission of all the images is executed again. After the transmission is completed, it is determined again in step S1101 whether the processing has ended in error or normal, and if an error has occurred, the above processing is repeated.

If "confirm untransmitted image" is selected in step S1114, an untransmitted image is displayed on image display section 28 of the camera in step S1115.

If "untransmitted image print" is selected in step S1116, Send_err. m
The rk image file information is converted into a format compatible with the well-known DPOF format (step S1117),
In step S1118, one of the jobs in the DPOF file is recorded on a memory card that stores images.
The user can easily print an untransmitted image by inserting the memory card into a direct printer or the like.

In this case, default settings may be made for information other than image designation information (for example, designation of standard print or index print), but various settings may be made.

When recording as one job in the DPOF file, a mark indicating that the job is a job for printing an untransmitted image or a special name may be added. When the user selects this job at the time of printing, even if another job is described in the DPOF file, only the untransmitted image can be printed.

[0119] Instead of creating a job, a new DPOF file may be created.

Also, in step S1119, "transmission end"
If has been selected, all transmission processing ends in S1120.
