Description

  The present invention relates to a file receiving server, its operation control method, and its control program.

When a still image or the like is uploaded to a web server or the like, image processing may be performed on the still image. For example, reduction to a desired size, generation of a thumbnail image, participation of a sponsor's logo, etc. In such a case, the system configuration is such that when it is confirmed that the uploading of the still image has been completed, predetermined image processing is performed. For example, when an image file is stored in a predetermined folder, image processing corresponding to the predetermined folder is performed (Patent Document 1).
JP 2003-280961 A

  However, it is necessary to monitor whether an image file is stored in a desired folder. Further, since image processing to be performed is predetermined, a user who uploads a still image cannot often determine or change the content of the image processing.

  It is an object of the present invention to set the content of image processing by a user who uploads an image.

  The file receiving server according to the present invention is an image file receiving means for receiving an image file transmitted from a client computer, a conversion instruction file represented by the image file receiving means, and an image received by the image stop receiving means. The conversion instruction file receiving means for receiving the conversion instruction file describing the conversion contents of the image represented by the file, received by the image file receiving means based on the conversion instruction file received by the conversion instruction file receiving means. Image conversion means for converting the image represented by the image file, and erasure means for erasing the conversion instruction file received by the conversion instruction file receiving means in response to the image conversion processing being performed by the image conversion means. With the features That.

  The present invention also provides an operation control method suitable for the file receiving server. That is, in this method, the image file receiving means receives the image file transmitted from the client computer, and the conversion instruction file receiving means is the conversion instruction file transmitted from the client computer. Receiving the conversion instruction file describing the conversion contents of the image represented by the image file received by the means, and the image conversion means based on the conversion instruction file received by the conversion instruction file receiving means; The image represented by the image file received by the receiving means is converted, and the erasure means converts the conversion instruction file received by the conversion instruction file receiving means in response to the image conversion processing being performed by the image converting means. It is to be erased.

  Furthermore, the present invention also provides a program for implementing the operation control method and a recording medium storing the program.

  According to the present invention, when the image file and the conversion instruction file are transmitted from the client computer, they are received by the file receiving server. The image represented by the received image file is converted according to the conversion contents described in the conversion instruction file. When the conversion process ends, the received conversion instruction file is deleted. Since the image is converted in accordance with the contents described in the conversion instruction file, the user who sends the image file transmits the conversion instruction file in which the desired conversion contents are described to the file receiving server, thereby obtaining the desired image. Conversion can be performed. In addition, since the conversion instruction file is deleted, it is possible to prevent the same conversion from being accidentally performed on an image file transmitted later.

  After the client computer logs in to the file receiving server, the image file receiving means permits the reception of the image file and the conversion instruction file receiving means to receive the conversion instruction file, and the client computer accepts the file receiving server. First control means for controlling the image file receiving means and the conversion instruction file receiving means so as to permit the image file receiving means to receive the image file and the conversion instruction file receiving means to receive the conversion instruction file after logout. , And during the login to the file receiving server by the client computer, the image file receiving means receives the image file and the conversion instruction file receiving means converts the conversion instruction file. Determination means for determining whether there is reception of may further comprise a. In this case, the image conversion means receives the image file based on the conversion instruction file received by the conversion instruction file receiving means in response to the determination means receiving the image file and the conversion instruction file. The image represented by the image file received by the means will be converted.

  Further, the image conversion process is stopped when the determination unit determines that at least one of the image file and the conversion instruction file has not been received during login to the file reception server by the client computer. A second control unit for controlling the image conversion unit may be further included.

  FIG. 1 shows an embodiment of the present invention and is an outline of a file communication system.

  The file communication system includes a client computer 1 and an FTP (File Transfer Protocol) server 10 that can communicate with each other via the Internet. In the file communication system according to this embodiment, an image file and a conversion instruction file are transmitted from the client computer 1 to the FTP server 10, and an image represented by the image file is converted in the FTP server 10 in accordance with the contents of the conversion instruction file. To do. When the user of the client computer 1 describes the contents of the conversion instruction file, the FTP server 10 can perform the conversion desired by the user of the client computer 1.

  FIG. 2 is a block diagram showing an electrical configuration of the FTP server 10.

  The overall operation of the FTP server 10 is controlled by the CPU 14.

  The FTP server 10 is provided with a CD (compact disk) drive 19. When the CD 20 storing an operation program for performing an operation to be described later is loaded in the CD drive 19, the operation program stored in the CD 20 is read into the FTP server 10 and installed.

  As described above, the FTP server 10 includes a communication device 11 for connecting to the Internet, a memory 12 for temporarily storing data, an input device 13 for inputting commands and the like, and displaying images and the like. A display device 15 and a clock 16 are included. The FTP server 10 also includes a hard disk 18 for storing image files and conversion instruction files transmitted from the client computer 1 and an HD (hard disk) drive 17 for accessing the hard disk 18.

  FIG. 3 shows an example of the directory structure of the hard disk.

  This directory structure is composed of client computers 1 to 001. an image file having a file name of jpg and 002. An image file having a file name of gif and _00Command. This is after the conversion instruction file having the file name txt is transmitted. This directory structure corresponds to a specific client computer 1, and when another client computer accesses the FTP server 10, another folder is formed.

  An image folder having an image folder name and a conversion instruction folder having a folder name of ftp_temp ¥ 20061231030959 are formed below the root directory. The image folder is formed before the image file is transmitted from the client computer 1. Of course, an image folder may be formed in response to the transmission of an image file from the client computer 1. The conversion instruction folder is formed in response to the conversion instruction file transmitted from the client computer 1. The number string included in the folder name of the conversion instruction folder indicates the time when the conversion instruction file is received by the FTP server 10 (the time is measured by the clock 6). This prevents the same conversion instruction folder from being formed.

  In the conversion instruction folder, _00Command. A conversion instruction file having a file name of txt is stored.

  In the image folder, 001. an image file having a file name of jpg and 002. An image file having a gif file name is stored. The image folder also stores a thumbnail image folder having a folder name of thumbnail_images and a resized image folder having a folder name of changed_images. The sent 001. Generated and sent a thumbnail image of the image represented by the jpg image file. When it is described that an image resized from the image represented by the gif image file is generated, a thumbnail image and a resized image are generated. An image file representing the generated thumbnail image is stored in a thumbnail image folder having a folder name of thumbnail_images, and an image file representing a resized image is stored in a resized image folder having a folder name of changed_images.

  FIG. 4 is an example of a conversion instruction script described in the conversion instruction file. There is no line item in the conversion instruction script, but a line item is added for convenience of explanation.

  The script on the first line indicates an instruction to generate a thumbnail image for an image file having an extension of jpg and store the generated thumbnail image in a thumbnail image folder having a folder name of thumbnail_images. The script on the second line, for an image file having a gif extension, generates an image having a size of 640 pixels in the horizontal direction and 480 pixels in the vertical direction by performing the resizing process, and the generated image is stored in a folder of the “resized_images” An instruction to store in a resized image folder having a name is shown.

  Such a conversion instruction file is 001. an image file having a file name of jpg and 002. By transmitting the image file having the file name of gif together with the image file from the client computer 1 to the FTP server 10, the image file or the like is stored in the FTP server 10 with the above-described directory configuration.

  FIG. 5 is a flowchart showing a communication processing procedure between the client computer 1 and the FTP server 10.

  In this communication processing procedure, as described above, the client computer 1 sends the 001. an image file having a file name of jpg, 002. An image file having a file name of gif and _00Command. It is assumed that a conversion instruction file having a file name of txt is transmitted.

  First, the client computer 1 is connected to the FTP server 10, and the client computer 1 is logged in to the FTP server 10 using a regular ID and password (steps 31 and 41). When logging in, an image file and a conversion instruction file are transmitted from the client computer 1 to the FTP server 10 (step 32).

  When the FTP server 10 receives a file transmitted from the client computer 1 (YES in step 42), the file name of the received file is “_00Command.txt, which is a file name of a predetermined conversion instruction file. Is checked (step 43).

  If the file name of the received file is “_00Command.txt” (YES in step 43), since the received file is a conversion instruction file, a temporary folder whose reception time is included in the file name is generated. , And stored in the generated temporary folder (step 44). If the file name of the received file is not “_00Command.txt” (NO in step 43), the received file is an image file and is stored in the image folder (step 45).

  Until the client computer 1 logs out, steps 42 to 45 are repeated (step 46).

  When the client computer 1 logs out (YES in steps 33 and 46), it is confirmed whether or not a conversion instruction file having a file name “_00Command.txt” is stored in the temporary folder (step 47). If stored (YES in step 47), the image represented by the received image file is converted according to the script described in the conversion instruction file (step 48). When the conversion instruction file in which the script shown in FIG. 4 is described is stored in the FTP server 10, a thumbnail image is generated for the image file having the extension of jpg as described above, and the generated thumbnail image is generated. Are stored in a thumbnail image folder having a folder name of thumbnail_images. A resized image is generated for the image file having the extension of gif, and the generated resized image is stored in a resized image folder having a folder name of “resized_images”.

  When the image conversion processing is completed, the conversion instruction file having the file name “_00Command.txt” stored in the temporary folder is deleted (step 49). If the conversion instruction file having the file name “_00Command.txt” stored in the temporary folder is not stored (NO in step 47), the processing in steps 48 and 49 is skipped, and the image conversion processing is performed. It will not be done. The presence or absence of image conversion processing is determined depending on whether the conversion instruction file is transmitted or not.
