(Embodiment 1)
FIG. 1 is a schematic block diagram showing the configuration of the mobile phone according to the first embodiment of the present invention.

In the figure, a control unit 1 is composed of a CPU (Central Processing Unit) and the like, and controls the entire mobile phone according to an operation program stored in a ROM (Read-Only Memory) 2. The communication unit 3 performs data communication such as a call and mail via a wireless base station (not shown). That is, the voice from the voice microphone is captured, converted into a digital signal and transmitted from the antenna 3-1 to the radio base station, while the voice signal from the radio base station is received from the antenna 3-1 and converted into an analog signal. Or output from the speaker. A RAM (random access memory) 4 stores various data including image data, and may be configured by either a built-in memory or a removable external memory. The camera unit 5 captures an image, and includes a lens, a CCD (CCD: Charge Coupled Device), which is an image sensor. The operation unit 6 inputs a telephone number, various data, a mode instruction, and the like. The display unit 7 includes a liquid crystal display and displays information such as an address book and a telephone number, various setting screens, captured images, and the like.

The image data stored in the RAM 4 is stored in an arbitrary designated folder among a plurality of folders at the time of shooting. The normal folder, the folder set by the user, the automatically generated early spring sunset folder It is memorized. The image data is stored in association with various shooting conditions such as a shot image size, zoom, and aperture.

Next, specific operations of the mobile phone according to the first embodiment will be described with reference to FIGS. 2 to 4 are flowcharts showing processing contents of the mobile phone, FIG. 5 is a diagram showing an example of a display screen of the mobile phone, and FIG. 6A is currently captured from the camera unit. FIG. 6 is a diagram schematically illustrating a captured image size of image data and a captured image size when the image data is expanded, and FIG. 6B schematically illustrates the captured image size of similar image data. It is a figure.

The processing of the flowcharts shown in FIGS. 2 to 4 is realized by software processing in cooperation with the control unit 1 and a program stored in the ROM 2. Specifically, the control unit 1 starts the process shown in FIG. 2 by reading a program from the ROM 2 and developing the program in the RAM 4 when the mobile phone is turned on.

First, FIG. 2 is a diagram showing an overall schematic operation of the mobile phone. The control unit 1 determines the mode (step A1), which is a standby screen in the initial setting. Until a mode instruction is input (not shown), the standby screen is displayed.

When a mode instruction is input, the mode is switched to the corresponding mode, so whether or not it is a shooting mode is determined in step A2, and if it is determined that it is a shooting mode (step A2; Y), a step of shooting processing Proceed to A3.

FIG. 3 is a diagram showing the detailed operation of the image capturing process. When the image capturing process of FIG. 3 is started, the control unit 1 first passes through the camera unit 5 if the shutter is half-pressed and is in the focus state. The image is captured and the through image is displayed on the display unit 7 (step B1).

Then, it is determined whether or not an instruction for setting various shooting conditions such as the shot image size, zoom, and aperture is made from the operation unit 6 (step B2), and an instruction for setting the shooting conditions is given. If so (step B2; Y), an input of various photographing conditions such as a photographed image size, zoom, and aperture made from the operation unit 6 is accepted (step B3). This photographing condition is not changed until the next setting instruction is given.

Further, in step B4, the camera unit 5 is controlled based on the zoom, aperture, etc. of the temporarily stored shooting conditions, and the corresponding mechanisms are operated. In step B5, it is determined whether or not the shutter has been fully pressed. If the shutter has not been fully pressed (step B5; N), the process goes through step A1.

However, if it is determined that the shutter is fully pressed (step B5; Y), the process proceeds to step B6.

Further, in step B6, the image data currently captured from the camera unit 5 and all the image data already stored in the RAM 4 are compared and searched, and in step B7, an image similar to the captured image data. It is determined whether data is already stored in the RAM 4.

That is, the image data currently captured from the camera unit 5 is converted into 16 gradation monochrome data, and all the image data already stored in the RAM 4 is also converted into 16 gradation monochrome data. The degree of coincidence of the image data is determined, and if there is a match of 90% or more, it is determined that similar image data has already been stored in the RAM 4 (step B7; Y), and there are a plurality of targets. In this case, the image data having the highest matching rate is determined as similar image data, and the process proceeds to step B9. On the other hand, it is determined in step B7 that image data similar to the RAM 4 is not stored. (Step B7; N), the process proceeds to Step B8.

Next, in step B8, the image data currently captured from the camera unit 5 is given a name, for example, year, date, hour, minute, and second, and the normal folder is associated with the image data together with the temporarily stored shooting conditions. And then return to step A1.

On the other hand, if it is determined in step B7 that image data similar to the RAM 4 is stored (step B7; Y), the process proceeds to step B9. In step B9, the image currently captured from the camera unit 5 is displayed. It is determined whether or not the captured image size of the data is the same as the captured image size of the similar image data determined in step B7. If the captured image size is the same (step B9; Y), the step is performed. Proceed to B11.

If the captured image size is not the same (step B9; N), the process proceeds to step B10. In step B10, the captured image size of the image data currently captured from the camera unit 5 is set to similar image data. Adjust to the same size as the captured image size.

That is, the size of the image is adjusted by compressing or expanding the image data itself currently captured from the camera unit 5 so as to be the same as the captured image size of the similar image data. As a result, the captured image size of the image data currently captured from the camera unit 5 is 320 × 240 pixels as shown in FIG. 6A, and the captured image size of similar image data is as shown in FIG. 6B. Even if it is 640 × 480 pixels, the image data currently captured from the camera unit 5 is expanded as shown in FIG. 6A to make the captured image size apparently 640 × 480 pixel image data. Thus, it can be adjusted to the captured image size of similar image data.

Instead of step B10, the captured image size of similar image data may be adjusted to be the same size as the captured image size of the image data currently captured from the camera unit 5. In this case, FIG. 6A shows that all of the image data in the folder in which similar image data is stored has the same size as the captured image size of the image data currently captured from the camera unit 5. The latest captured image size newly specified by the user is reflected.

Furthermore, it is also possible to temporarily change the shooting size itself of the shooting conditions, and to adjust the shot image size by capturing from the camera unit 5. In this case, after capturing the image from the camera unit 5, the original shooting You can return to the shooting size of the condition.

In step B11, it is determined whether or not similar image data is stored in the normal folder. If similar image data is stored in the normal folder (step B11; Y), the image data is currently captured. Since the image data related to the image data is already stored in the normal folder, the process proceeds to step B12 in order to combine the image data similar to another folder and the currently captured image data.

Next, in step B12, a new folder is automatically created. For example, a new folder is automatically created with the name of the season, time zone, serial number, etc., as shown in FIG. As shown in the screen of the display unit 7, a new folder is automatically created with a name such as “early spring sunset folder 1”.

Next, the process proceeds to step B13, and the similar image data and the photographing conditions corresponding to the similar image data are moved to the new folder and stored, and the process proceeds to step B14.

Note that the processing in steps B11 to B13 is not necessarily required, and the image data may be stored in separate folders, and even in this case, they can be stored with the same image size.

In step B14, the image data currently captured from the camera unit 5 is given a name, for example, year, date, hour, minute, and second, and the temporarily stored shooting conditions (the shot image size has been adjusted). (Image size) and the image data are stored in a new folder in association with each other, and then the process returns to step A1. As a result, similar image data and currently captured image data can be stored together with the same image size.

Returning to FIG. 2, if it is determined in step A2 that the camera mode is not set (step A2; N), it is determined whether or not the call mode is set (step A4), and if the call mode is set (step A4). Y), the process proceeds to step A5 of the call processing. This call process performs processes such as standby, call, and mail transmission / reception.

If it is determined in step A4 that the call mode is not set (step A4; N), whether or not the image size adjustment mode is used to adjust the image size when an arbitrarily designated image is moved between folders. Is determined (step A6).

If it is determined that the mode is not the image size adjustment mode (step A6; N), the process proceeds to other processing (step A7) for reproducing the image, setting the captured image size of the folder, and other various settings. If it is determined that the image size adjustment mode is set (step A6; Y), the process proceeds to step A8 of the image size adjustment process. FIG. 4 is a diagram showing the detailed operation of the image size adjustment processing. First, image data to be processed to be moved is read (step C1).

In this case, the image data to be processed is read out by designating an arbitrary folder from among a plurality of folders displayed on the screen of the display unit 7, and thumbnail images of the image data stored in the designated folder. By displaying and designating a desired thumbnail image among the thumbnail images, the image data to be processed is read out and displayed on the screen of the display unit 7, and the image data to be processed to be moved is read out. After performing, the designation of the folder to be moved is performed in step C2 according to the operation of the input unit 6.

In addition, it is assumed that the captured image size is preset in each folder. For example, it is assumed that 320 × 240 pixels are set by default in the normal folder, and values arbitrarily set by the user are set in advance in the other folders. Then, the processing target image data to be moved is compressed or expanded so as to be the captured image size set in the folder designated as the movement destination, and the image size of the processing target image data to be moved is set. Then, the adjusted image data and the shooting conditions (the shot image size is the adjusted shot image size) are stored in the destination folder and stored in the original folder. The image data to be processed is deleted (step C4).
(Embodiment 2)

  FIG. 7 is a diagram showing detailed operations of another example of the photographing process in the mobile phone according to the second embodiment of the present invention. When the photographing process of FIG. If is pressed halfway and is in the focus state, a through image is taken from the camera unit 5 and displayed on the display unit 7 (step D1).

In step D2, the image data of the through image currently captured from the camera unit 5 (hereinafter referred to as through image data) is compared with all the image data already stored in the RAM 4, and in step D3, It is determined whether image data similar to the captured through image data is already stored in the RAM 4.

That is, the through image data currently captured from the camera unit 5 is converted into 16-tone monochrome data, and all the image data already stored in the RAM 4 is also converted into 16-tone monochrome data. Then, the degree of coincidence of the image data is determined, and if there is a match of 90% or more, it is determined that similar image data has already been stored in the RAM 4 (step D3; Y), and a plurality of objects are determined. In some cases, the image data having the highest matching rate is determined as similar image data and proceeds to step D9. On the other hand, in step D3, it is determined that image data similar to the RAM 4 is not stored. Then (step D3; N), the process proceeds to step D4.

In step D4, it is determined whether or not an instruction for setting various shooting conditions such as a shot image size, zoom, and aperture is made from the operation unit 6, and an instruction for setting the shooting condition is given. If so (step D4; Y), an input of various photographing conditions such as a photographed image size, zoom and aperture made from the operation unit 6 is accepted (step B3). This photographing condition is not changed until the next setting instruction is given.

Further, in step D6, the camera unit 5 is controlled based on the zoom, aperture, etc. of the temporarily stored shooting conditions, and the corresponding mechanisms are operated.

In step D7, it is determined whether or not the shutter has been fully pressed. If the shutter has not been fully pressed (step D7; N), the process goes to step A1 through this flow. However, if it is determined that the shutter is fully pressed (step D7; Y), the process proceeds to step D8.

Next, in step D8, a name such as year, date, hour, minute, and second is assigned to the image data currently captured from the camera unit 5, and the normal folder is associated with the image data together with the temporarily stored shooting conditions. And then return to step A1. On the other hand, if it is determined in step D3 that image data similar to the RAM 4 is stored (step D3; Y), the process proceeds to step D9.

Then, in step D9, it is determined whether or not the shutter has been fully pressed. If the shutter has not been fully pressed (step D9; N), the process goes to step A1 through this flow. However, if it is determined that the shutter is fully pressed (step D9; Y), the process proceeds to step D10.

In step D10, it is determined whether or not similar image data is stored in the normal folder. If similar image data is stored in the normal folder (step D10; Y), the image data is currently captured. Since the image data related to the through image data is already stored in the normal folder, the process proceeds to step D11 in order to combine the image data similar to another folder and the image data currently captured.

Step D11 is a process for automatically creating a new folder. For example, a new folder is automatically created with the name of the season, time zone, serial number, etc. at that time, and the display section shown in FIG. As shown in the screen of FIG. 7, a new folder is automatically created with a name such as “early spring sunset folder 1”.

Next, the process proceeds to step D12, where the similar image data and the photographing conditions corresponding to the similar image data are moved to the new folder and stored, and the process proceeds to step D13.

In step D13, a name such as year, date, hour, minute and second is used as a name for the through image data currently captured from the camera unit 5, and is associated with the image data together with the temporarily stored shooting conditions. Store in the new folder, and then return to step A1. Accordingly, similar image data and currently captured image data can be stored together, and for example, images of a specific person, landscape, and the like can be combined. Before step D13, as shown in step B10, an adjustment process is performed to make the captured image size of the image data currently captured from the camera unit 5 the same size as the captured image size of similar image data. Thus, the captured image sizes of similar image data can be matched.

Accordingly, similar image data and currently captured image data can be stored with the same image size. In addition, if there is no similar image, the image can be taken based on a preset image size setting. Further, when the image size of similar image data is different from the image size of the currently captured image data, the image size of the currently captured image data can be adjusted.

Furthermore, the image data currently captured and the recorded image can be stored with the same image size. In addition, the image size of the currently captured image data can be adjusted to be the same as the image size of the recorded image. In addition, the image size of the recorded image can be adjusted so as to be the same as the image size of the currently captured image data.

Furthermore, when storing image data, it can be stored in a file of the same image type. Further, the size of the image data can be adjusted and stored based on the image size stored in advance in the file.

A program for realizing the mobile phone according to the above-described embodiment is recorded on a portable recording medium or the like, and the recorded program is read out from the portable recording medium or the like and used to realize the new function of the present invention. May be. In this case, as a portable recording medium for supplying the program, for example, a flexible disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a DVD-ROM, a DVD-RAM, a magnetic tape, a non-volatile Any memory card or ROM card may be used.

Further, the functions of the above-described embodiments may be realized by executing a program received by e-mail or infrared communication.
