The communication destination may be any identification information of a communication destination that is unique in the communication network to which the communication unit 15 of the mobile communication terminal 1 is connected, such as a telephone number or an e-mail address. A communication destination group in which a plurality of communication destinations are classified may be registered in the address book as a communication partner. In the following description, the communication destination includes the communication destination group unless otherwise specified.

[Process flow]
Hereinafter, the flow of folder creation processing, image storage processing, and image transmission processing executed by the CPU 10 will be described. First, the flow of folder creation processing will be described with reference to the flowchart of FIG.

  In S <b> 1, an input of a communication destination is received from the operation unit 11. Note that the number of communication destinations that can be input is not necessarily one, and a plurality of communication destinations may be input simultaneously. In S2, it is determined whether or not an instruction to communicate with the input communication destination is input from the operation unit 11. This instruction can be performed by, for example, pressing a call start key, which is an aspect of the operation unit 11, or pressing a touch panel displaying an e-mail transmission button. If an instruction to communicate is input, the process proceeds to S3, and if not input, the process proceeds to S4. In S3, communication is performed with the input communication destination. The communication may be anything as long as it communicates with an input communication destination via a communication network. For example, if the input communication destination is a telephone number, a call voice signal is transmitted / received to / from the other party telephone. When the input communication destination is an e-mail address, the e-mail is transmitted to the e-mail address.

  In S4, it is determined whether or not an instruction to register the input communication destination in the address book is input from the operation unit 11. If a registration instruction is input, the process proceeds to S5. If a registration instruction is not input, the process returns to S2. In S5, a screen for notifying that the input communication destination is registered in the address book is displayed on the display unit 17. In S6, the input communication destination is registered in the address book. In S <b> 7, a screen for confirming whether or not to create a communication destination folder that is a folder corresponding to the input communication destination is displayed on the display unit 17.

  In S <b> 8, it is determined whether or not an instruction for creating a communication destination folder is input from the operation unit 11. If an instruction to create a folder corresponding to a communication destination is given, the process proceeds to S9, and if an instruction to create is not given, the process returns to S1. In S9, a communication destination folder is created in the memory card 2.

  According to the above processing, since a folder corresponding to the communication destination managed in the address book is created in the memory card 2 (S9), various data (specifically, image files) corresponding to the communication partner in this folder are stored. Classification can be performed.

  Next, the flow of folder creation processing will be described with reference to the flowchart of FIG.

  In S <b> 11, it is determined whether a shooting mode transition instruction is input from the operation unit 11. If a shooting mode transition instruction is input, the process proceeds to S12. If a shooting mode transition instruction is not received, the instruction is continued. The shooting mode is a mode for shooting an image and is distinguished from other operation modes of the mobile communication terminal 1.

  In S12, it is determined whether or not an instruction to display an address book is input from the operation unit 11. If an instruction to display the address book is input, the process proceeds to S13. If an instruction to display the address book is not input, the process proceeds to S15. In S13, the address book is displayed, and in S14, selection of an arbitrary communication destination from the communication destinations registered in the address book is accepted from the operation unit 11. As will be described later, the image data is stored in the communication destination folder corresponding to the communication destination selected in this step.

  In S15, it is determined whether or not an instruction to start shooting is input from the operation unit 11. If an instruction to start shooting is input, the process proceeds to S16. If not input, an instruction to start shooting is continuously waited. Note that if the RTN key is pressed during this standby, the image storage process may be terminated. In S16, the CCD 12 starts imaging, and digital image data is output via the analog front end IC 13 and the signal processing IC. This image data is temporarily stored in the RAM 21.

  In S17, it is determined whether or not a communication destination has been selected in S14. When the communication destination is selected, the process proceeds to S18, and when the communication destination is not selected, the process proceeds to S20. In S18, it is determined whether or not a communication destination folder corresponding to the communication destination selected in S14 has been created in the memory card 2. When the corresponding communication destination folder is created, the process proceeds to S19, and when the corresponding communication destination folder is not created, the process proceeds to S20.

  In S19, the image data in the RAM 21 is converted into an image file such as a JPEG file, and this image file is stored in the communication destination folder corresponding to the communication destination selected in S14. In S20, the display unit 17 displays that the corresponding communication destination folder has not been created. In S21, the image file is stored in a normal folder other than the communication destination folder. The normal folder is created in the memory card 2 in advance.

  According to the above processing, since the image data is stored in the folder corresponding to the communication destination managed in the address book (S19), the image data can be classified according to the communication destination in the folder.

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

  In S31, it is determined whether or not an instruction to display an address book is input from the operation unit 11. If an instruction to display the address book is input, the process proceeds to S32. If an instruction to display the address book is not input, the instruction is continuously waited. In S32, the address book is displayed on the display unit 17, and in S33, selection of an arbitrary communication destination from the communication destinations registered in the address book is accepted from the operation unit 11.

  In S34, an input of an instruction as to whether or not all the image files stored in the communication destination folder corresponding to the communication destination selected in S33 are to be collectively transmitted to the communication destination selected in S33 is performed from the operation unit 11. Accept. If an instruction to transmit an image file is input, the process proceeds to S36. If an instruction to transmit an image file is not input, the process proceeds to S35. In S35, communication is performed with the selected communication destination.

In S36, it is determined whether or not a communication destination folder corresponding to the communication destination selected in S33 has been created in the memory card 2. If the corresponding communication destination folder has been created, the process proceeds to S38, and if not, the process proceeds to S37. In S <b> 37, the display unit 17 displays that no corresponding communication destination has been created.

  In S38, it is determined whether or not at least one image file is stored in the communication destination folder corresponding to the communication destination selected in S33. If at least one image file is stored in the corresponding communication destination folder, the process proceeds to S40, and if no image file is stored, the process proceeds to S39. In S39, the display unit 17 displays that it is not stored at all in the communication destination folder.

  In S40, it is determined whether or not the communication destination selected in S33 is appropriate as an image file transmission destination. For example, when the image file is transmitted by e-mail, it is determined whether or not the communication destination selected in S33 is an e-mail address instead of a telephone number. However, depending on the cellular phone communication carrier, an image file may be transmitted by specifying a telephone number, and therefore, only an e-mail address is not always appropriate as a destination of the image file. If the communication destination selected in S33 is appropriate as the transmission destination of the image file, the process proceeds to S41. If not, the process proceeds to S42.

  In S41, the image stored in the communication destination folder corresponding to the communication destination selected in S33 is transmitted to the communication destination selected in S33. In S42, the display unit 17 displays that the communication destination selected in S33 is not appropriate as the transmission destination of the image file.

  According to the above processing, since the image files stored in the folder corresponding to the communication destination managed in the address book are transmitted to the communication destination (S41), the image files classified by the folder are selected at once. Can be sent to the other party.

  Note that a program for causing the CPU 10 to execute the processing steps S1 to S9 included in the above-described folder creation processing, S11 to S21 included in the image storage processing, and S31 to S42 included in the image transmission processing is stored in the RAM 21. . These programs may be provided by being recorded on various recording media such as CD-ROM and DVD, or may be distributed via a network such as the Internet.

<Other embodiments>
(1) The address book may be registered in correspondence with the communication environment (communication speed level, etc.) of each communication destination. Then, in the above-described image storage processing, processing for setting shooting conditions according to the communication environment corresponding to the selected transmission destination may be performed. FIG. 5 is a flowchart in a case where such shooting condition setting processing is added to the image storage processing of the first embodiment. In this figure, S101 to S105 are the same as S11 to S15, and S113 to S116 are the same as S18 to S21, respectively. In S106, it is determined whether or not a communication destination has been selected, as in S17. If it is selected, the process proceeds to S107, and if it is not selected, the process proceeds to S110. In S107, it is determined whether a communication environment corresponding to the selected communication destination is registered in the address book. If the communication environment is registered, the process proceeds to S108, and if not registered, the process proceeds to S109.

  In S <b> 108, shooting conditions corresponding to the communication environment corresponding to the selected communication destination are set in the imaging unit 22. For example, if the communication speed is “low”, the shooting conditions for black and white shooting with small size VGA are set. If the communication speed is “medium”, the shooting conditions for color shooting with VGA are set. ", The shooting conditions for large-size XGA are set for color shooting. On the other hand, in S109, normal shooting conditions (such as color shooting with VGA) are set. In S111, shooting is performed under the shooting conditions set in S108 or 109, and the process proceeds to S113. If the communication destination is not selected, normal shooting conditions are set in S110, shooting is performed under these shooting conditions in S112, and the obtained image is stored in a normal folder in S116. Through the above processing, image data according to the communication environment of the communication destination can be generated, and the load on the communication destination that collectively transmits the image data in the folder by the image transmission processing is reduced.

  (2) In the same manner as described above, the address book can be registered in association with the communication environment of each communication destination, and in the image transmission processing of the first embodiment, the RAM 21 according to the communication environment corresponding to the selected transmission destination. The image data may be compressed. FIG. 6 is a flowchart when an image compression process is added to the image transmission process of the first embodiment. S131 to 140 are the same as S31 to 40, respectively. In S141, it is determined whether or not a communication environment corresponding to the communication destination selected in S133 is registered in the address book. If the communication environment is registered, the process proceeds to S143, and if not registered, the process proceeds to S144. In S143, the image file in the transmission folder corresponding to the selected transmission destination is compressed according to the communication environment corresponding to the selected transmission destination. S142 and S144 are the same as S42 and S41, respectively. As described above, the image file can be resized according to the communication environment of the communication destination and then transmitted to the communication destination, thereby reducing the communication load. In particular, it is possible to change the size of an image file obtained by an image storage process to which the above-described shooting condition setting process is added. That is, it is convenient that the image file size can be freely changed after shooting as well as during shooting.

  (3) The address book may be registered in correspondence with the shooting conditions of each communication destination. Then, in the above-described image storage process, it may be possible to set shooting conditions corresponding to the selected transmission destination. FIG. 7 is a flowchart when the shooting condition setting process is added to the image storage process of the first embodiment. S201 to S205 are the same as S11 to 15 of the first embodiment, respectively. In S206, it is determined whether or not a communication destination is selected as in S17. If it is selected, the process proceeds to S207, and if it is not selected, the process proceeds to S208. In S207, shooting conditions corresponding to the communication destination are set in the imaging unit 22. The imaging condition is the same concept as described above, and includes the resolution / color of the captured image, the image compression rate, and the like. In step S209, shooting is performed under the set shooting conditions. If no communication destination is selected, normal shooting conditions are set in S208, shooting is performed under the set shooting conditions in S210, and the obtained image data is stored in a normal folder in S214. S211 to S214 are the same as S18 to S21, respectively. Through the above processing, it is possible to set a shooting condition according to the communication destination selected from the address book and take a picture.

  (4) The communication destination folder and the normal folder may be created in various storage media other than the memory card 2. For example, when an image file is stored in the flash memory 19, a communication destination folder may be created in the flash memory 19 correspondingly.
