JP4297865B2 - Mobile communication terminal with camera - Google Patents

Description

  The present invention relates to a camera-equipped mobile communication terminal, and more specifically, can display a menu screen composed of two or more icon images, and can use an image taken by an electronic still camera as the icon image. The present invention relates to a portable communication terminal with a camera.

  Recent mobile phones have become more multifunctional and are equipped with functions such as a telephone directory, e-mail, WEB browser, calculator, camera, schedule management as well as a telephone function. For this reason, most mobile phones display a menu screen for function selection, and allow the user to select a desired function.

  Generally, a display of a mobile phone is narrower and has a lower resolution than a display of another information processing apparatus. The menu screen displayed on such a display displays each option as an icon image in order to display more options simultaneously and to display intuitively and easily. In such a menu screen, usually one of the icon images is focused, and the user operates the direction key to move the focus to the desired icon image and operates the enter key. The desired option can be selected.

  In addition, a mobile phone that allows a user to customize such an icon image has been conventionally proposed (for example, Patent Document 1). In the mobile phone described in Patent Literature 1, the user can freely change the correspondence between each option constituting the menu screen and the icon image prepared in advance.

Further, there is a mobile phone that can use arbitrary image data as the icon image. That is, there has been a mobile phone that can use, as an icon image, image data taken by a camera mounted on the mobile phone, image data downloaded from a WEB server, or image data obtained as an attached file of an e-mail.
Japanese Patent Laid-Open No. 11-17789 (FIG. 3)

  The icon image displayed on the menu screen has a predetermined pixel size. Therefore, when any image data is adopted as the icon image, the pixel size of the image data must be converted to the pixel size of the icon image. In other words, there is a problem that the user has to perform trimming or enlargement / reduction of image data in advance on the image editing application, which involves complicated work.

  In addition, changing the pixel size usually requires enlargement processing or reduction processing of the image data, but these processing deteriorates the image quality and makes it difficult to read the icon image. In particular, an icon image of a mobile phone has a small number of pixels and is considered to often have to be reduced. However, when the reduction process is performed, as the number of pixels decreases, fine depictions such as thin lines disappear, resulting in an unclear image, often resulting in an icon image that is difficult to identify. In particular, such a tendency is remarkable in image data captured by a camera, and there are many cases where the subject cannot be identified by the reduction process.

  Furthermore, when arbitrary image data is converted into an icon image, there is a case where compatibility with the focus is deteriorated. For example, if the focus is a white frame displayed on the periphery of the icon image, using the image data with a white periphery as the icon image, it is possible to distinguish between the focused state and the unfocused state. There is a problem that it is difficult to determine the focus position.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a camera-equipped mobile communication terminal that can easily use a captured image captured by a built-in camera as an icon image on a menu screen. It is another object of the present invention to provide a camera-equipped mobile communication terminal that allows a user to capture a desired icon image using a built-in camera. Furthermore, it aims at providing the portable communication terminal with a camera which can perform camera imaging | photography in consideration of compatibility with a focus.

A selection icon generating means for generating a moving image for a selection icon consisting of an image, and using the moving image for the selected icon as a focused option, and using the icon image as another option, the menu screen is displayed. A menu screen generating means for generating the image, and the photographing processing means trims the photographed image and converts it into a trimmed image having the pixel size, and each of the focus images included in the trimmed image. Each frame image is composed and composed of multiple frame images. A selection icon processing means for generating a video finder screen, in the photographing mode, and the finder screen generating means for generating a viewfinder screen based on video for the finder screen, based on the shutter operation, the trimming image Image writing means for storing in the icon image storage means.

With such a configuration, when an icon image displayed as an option on the menu screen is shot with an electronic still camera, the shot image is trimmed, and a trimmed image that matches the pixel size of the icon image is displayed as an icon image. Stored in storage means. For this reason, even if a user does not adjust the pixel size of the picked-up image image | photographed with the electronic still camera anew, it can utilize as an icon image. Next, the photographed image is converted into a trimmed image having the pixel size of the icon image, and the finder screen is generated based on the trimmed trimmed image. Therefore, the display image on the finder screen is converted into an icon image obtained by photographing. Can be matched. Furthermore, the focus image can be combined with the trimmed image, and the selected icon image having the trimmed image as an icon image can be confirmed on the viewfinder screen and photographed. Furthermore, in the mobile communication terminal in which the selected icon image obtained by combining the icon image with the focus image of the moving image is displayed for the option that is focused on the menu screen, the user can display the viewfinder screen during the icon image shooting mode. The icon image can be taken while checking the compatibility with the focus image of the moving image.

The second mobile communication terminal with a camera according to the present invention, in addition to the above structure, the photographing processing means, in the photographing mode, generates an enlarger trimming image by stretching the trimmed image to an integer multiple of the pixel size, the The selection iconification processing unit is configured to generate a moving image for the viewfinder screen including the enlarged focus image and the enlarged trimmed image . With such a configuration, it is possible to make the viewfinder screen easier to see while completely matching the information amount of the display image on the viewfinder screen and the icon image obtained by shooting.

Embodiment 1 FIG.
FIG. 1 is an external view showing an example of a mobile communication terminal according to Embodiment 1 of the present invention, in which a mobile phone is shown. This mobile phone is provided with a display 11, a large number of operation keys 12, a call receiver 15, and a call microphone 16 on an operation surface facing the user. A built-in camera 13 and a flashlight 14 are provided on the surface opposite to the operation surface.

  The user can perform an operation input using the operation keys 12 while browsing the display 11 including a liquid crystal display device (LCD). The operation keys 12 include not only a numeric keypad used for dial operation but also a direction key capable of inputting four directions, up, down, left and right, a determination key, a shutter key used at the time of camera photographing, and the like. The built-in camera 13 is an electronic still camera that captures a still image and generates a captured image composed of digital data. A CCD or CMOS image sensor is used as an imaging device. The flashlight 14 is a light emission means for exposure adjustment that is turned on when underexposed shooting is performed, and a light emitting diode is used.

  When the user selects a function, a menu screen is displayed on the display 11. The user can select and execute a desired function by operating the direction key while viewing the menu screen, moving the focus to a desired option, and operating the enter key. In the shooting mode in which the shutter operation is possible, a finder screen is displayed on the display 11. This finder screen is a screen on which a captured image captured by the built-in camera 13 is displayed in real time, and the user performs shooting by operating the shutter key while looking at the finder screen.

  FIG. 2 is a block diagram showing an example of the configuration inside the mobile phone of FIG. The main control unit 20 includes a processor and a memory that perform main control of the mobile phone. The radio unit 21 performs radio communication with a cellular radio base station (not shown) via an antenna. The display control unit 22 is an LCD controller that performs drive control of the display 11 based on screen data from the main control unit 20. The voice control unit 23 performs input / output control of the call voice, and outputs a received sound to the call receiver 15 and receives a send sound from the call microphone 16.

  When the user performs a key operation, a key operation signal is output from the operation key 12 to the main control unit 20. Based on the key operation signal, the main control unit 20 performs menu screen display and camera shooting operation control. The built-in camera 13 performs imaging based on a control signal from the main control unit 20 and outputs a captured image to the main control unit 20.

  When the operation mode of the mobile phone is a menu display mode for selecting a function, the main control unit 20 generates a menu screen, and this menu screen is displayed on the display 11. At this time, when a direction key operation signal is input, the main control unit 20 generates a menu screen on which the focus is moved. When the operation signal for the enter key is input, the main control unit 20 ends the display of the menu screen and executes the selected function.

  On the other hand, if the operation mode of the mobile phone is a shooting mode in which a shutter operation is possible, the main control unit 20 outputs a monitor shooting signal. The built-in camera 13 repeatedly performs monitor shooting at a constant cycle based on the monitor shooting signal, and periodically outputs shot images. The main control unit 20 in the shooting mode generates a finder screen from the shot image and displays it on the display 11. Thereafter, when the user performs a shutter operation, a photographing signal is output from the main control unit 20 to the built-in camera 13. At this time, the main control unit 20 stores the captured image output from the built-in camera 13 in the memory.

  FIG. 3 is a block diagram showing a configuration example of the main part of the main control unit 20 of FIG. As described above, the main control unit 20 includes a processor, and each block illustrated is realized as software executed by the processor. The main control unit 20 includes a nonvolatile memory 30, a photographing processing unit 40, and a menu processing unit 50.

  The nonvolatile memory 30 is a storage means that does not require power supply for data retention, such as a flash memory. The nonvolatile memory 30 includes a menu information storage unit 31, an icon image storage unit 32, and a background image storage unit 33.

  The icon image storage unit 32 holds two or more icon images. In this icon image storage unit 32, at least a default icon image is stored in advance as an icon image at the time of factory shipment, and arbitrary image data created by the user can be added as an icon image. Each icon image is composed of one data file, and not only a still image format such as JPEG, GIF, and BMP but also an operation format such as animation GIF can be used as the data format. That is, a moving image can be adopted as the icon image.

  The background image storage unit 33 holds one or more background images. A background image is an image (so-called wallpaper) that is displayed in an area where icons on the standby screen or menu screen are not arranged, and at least a default background image is stored in advance at the time of shipment from the factory. Arbitrary image data can be added as a background image.

  The menu information storage unit 31 holds menu information that defines a menu screen. When there are a plurality of types of menu screens, the menu information storage unit 31 holds menu information for each menu screen. The menu information is made up of information related to each option constituting the menu screen. Here, it is assumed that the function, name, display position, and icon image for each option are held.

  FIG. 4 is a diagram showing an example of menu information held in the menu information storage unit 31 of FIG. Each sheet shown corresponds to the menu information 70 to 72, and each row in this sheet corresponds to an option. Each option is associated with a function (program) that is executed when the option is selected. In addition, a name (text information) for each option is stored. This name is displayed by overlapping (superimposing) the icon image. For each option, the display position in the menu screen is stored.

  Further, two icon images are associated with each option. In the present embodiment, even if the options are the same, different icon images are displayed depending on whether the focus is applied or not, so that the presence or absence of the focus can be identified. For this reason, for the same option, two icon images are displayed that are displayed as a selected icon with focus and an icon image that is displayed as an unselected icon with no focus. Yes.

  The menu information 70 to 72 can be changed by a user operation. For this reason, the position in the menu screen of each option mentioned above, the link information to an icon image, etc. can be customized. Further, the icon image captured by the camera can be displayed on the menu screen by rewriting the link information to the icon image in the menu information 70 to 72.

  The photographing processing unit 40 generates a finder screen based on the photographed image output from the built-in camera 13 during the photographing mode, and outputs it to the display control unit 22 as screen data. If there is a shutter operation during the shooting mode, a save confirmation screen is generated and output to the display control unit 22 as screen data. When the user performs a confirmation operation, the captured image is stored in the nonvolatile memory 30. The photographing processing unit 40 further includes an image trimming unit 41, a finder screen generating unit 42 and an image writing unit 43.

  The image trimming unit 41 trims (cuts out) a captured image from the built-in camera 13 to a pixel size according to a capturing purpose designated by the user to generate a trimmed image. That is, the size of the image data is adjusted according to the shooting purpose. For example, when an icon image is captured, trimming to a predetermined pixel size of the icon image is performed, and when a background image is captured, trimming to a predetermined pixel size of the background image is performed. When a full-size image having the same size as the captured image is captured, the image trimming unit 41 does not perform trimming, and the captured image becomes a trimmed image as it is.

  The finder screen generation unit 42 generates a finder screen based on the trimmed image. When the icon image is taken, the trimmed image is stretched to generate an enlarged trimmed image whose vertical and horizontal pixel numbers are integer multiples of the trimmed image and that does not protrude from the viewfinder screen. A viewfinder screen containing is generated. Note that when shooting a full-size image that is larger than the viewfinder screen, a viewfinder screen including a reduced trimmed image obtained by reducing the trimmed image is generated. Here, the size of the finder screen is assumed to be the same as the display size of the display 11.

  FIG. 5 is an explanatory diagram showing an example of a viewfinder screen generation process at the time of shooting an icon image. (A) to (d) in the figure show a captured image, a trimmed image, an enlarged trimmed image, and a viewfinder screen, respectively. In general, the pixel size that can be displayed on the display 11 of the mobile phone is much smaller than the pixel size of the captured image of the built-in camera 13, and the pixel size of the icon image is further smaller than the pixel size of the display 11. . Here, it is assumed that the size of the captured image is 1224 × 1632 pixels (2 megapixels), the size of the finder screen is 240 × 320 pixels, and the size of the icon image is 76 × 76 pixels.

  At the time of shooting an icon image, the image trimming unit 41 cuts out a 76 × 76 pixel image located at the center of the shot image as a trimmed image. The viewfinder screen generation unit 42 doubles the number of vertical and horizontal pixels of the trimmed image to generate an enlarged trimmed image of 152 × 152 pixels, and a viewfinder screen in which the enlarged trimmed image is arranged at the center is generated. . This viewfinder screen is displayed on the display 11.

  That is, the user can perform the shutter operation while viewing image data having the same information amount as the icon image obtained by shooting. For this reason, if it is displayed as an icon image later, the impression is greatly different from the image seen on the viewfinder screen, and there is no possibility of missing a photo opportunity. In particular, after shooting as image data of a large pixel size, if you try to reduce the number of pixels on the image editing application and reduce it to the pixel size of the icon image, detailed image information disappears and unexpected icons The problem of becoming an image is eliminated.

  Next, processing at the time of shutter operation will be described. During the shooting mode in which the shutter can be operated, the above-described finder screen is displayed on the display 11. When the user performs a shutter operation in this state, the finder screen generation unit 42 holds the trimmed image at the time of the shutter operation and saves the confirmation screen for prompting the user to perform a confirmation operation for saving the image in the nonvolatile memory 30. Is output to the display control unit 22 as screen data. If the user performs a confirmation operation in this state, the image writing unit 43 stores the trimmed image at the time of the shutter operation in the nonvolatile memory 30. If the icon image is being shot, it is stored in the icon image storage unit 32, and if the icon image is being shot, it is stored in the background image storage unit 33.

  On the save confirmation screen at the time of shooting other than the icon image, an image generated through the same processing as that on the viewfinder screen is displayed for the shot image at the time of the shutter operation. For example, in the case of a full-size image, a reduced captured image is displayed. On the other hand, instead of the enlarged trimmed image in the case of the finder screen, the trimmed image is displayed on the save confirmation screen when the icon image is captured. That is, an image that has been subjected to the trimming process but not the enlargement process is displayed on the captured image at the time of the shutter operation.

  FIG. 6 is an explanatory diagram showing an example of a viewfinder screen and a save confirmation screen when an icon image is taken. Since the enlarged trimmed image is displayed on the finder screen shown in (a) in the drawing, the icon image that can be photographed can be confirmed accurately in pixel units, and it is easy to see because it is enlarged.

  On the other hand, on the save confirmation screen shown in (b), a trimmed image is displayed and displayed under exactly the same conditions as when it is displayed as an icon image. For this reason, the user can determine whether or not the captured icon image is actually stored on the display after confirming it on the storage confirmation screen. Further, in the photographing processing unit 40, since the trimming processing to the pixel size of the icon image is completed at the time of photographing, it is not necessary to start the image editing application and perform complicated work for size adjustment after that. It can be used as an icon image as it is.

  Next, the menu processing unit 50 in FIG. 3 will be described. The menu processing unit 50 generates a menu screen including two or more icon images as options during the menu display mode. The menu processing unit 50 further includes a focus control unit 51 and a menu screen generation unit 52.

  The focus control unit 51 performs focus movement control within the menu screen. In the menu screen, any one option is always focused, and the focus control unit 51 moves the focus between the options based on the operation signal of the direction key, and the focus is applied. Are output to the menu screen generation unit 52.

  The menu screen generation unit 52 generates a menu screen based on the menu information storage unit 31, the icon image storage unit 32, and the background image storage unit 33, and outputs the menu screen to the display control unit 22. On this menu screen, a selection icon image is displayed for the option with focus, and a non-selection icon image is displayed for the other options. In addition, both the selected icon image and the non-selected icon image are displayed by overlapping the names of options (superimpose). In addition, a background image is displayed in an area in the menu screen where icons are not displayed.

  FIG. 7 is a diagram showing an example of the menu screen. In this menu screen, nine icon images are arranged and displayed. In (a) in the figure, the left hand option is focused toward the middle, the selection icon is displayed only for this option, and the non-selection icon is displayed for the other options. (B) is a menu screen when the user operates the right direction key in the state of (a). The focus has moved to the middle option in the middle. That is, a selection icon is displayed only for this option, and a non-selection icon is displayed for other options.

  Steps S101 to S110 in FIG. 8 are a flowchart illustrating an example of an icon image shooting process. When the icon image shooting mode is entered, first, the built-in camera 13 performs monitor shooting based on a monitor shooting signal from the main controller 20, and outputs a shot image (step S101). The captured image is trimmed by the image trimming unit 41 to become a trimmed image having the pixel size of the icon image (step S102). The trimmed image is generated by the finder screen generation unit 42 after the number of vertical and horizontal pixels is expanded to an integral multiple, and then a finder screen including the enlarged trimmed image is generated and displayed on the display 11 (steps S103 and S104). . Steps S101 to S104 are periodically repeated until the user operates the shutter key (step S105).

  When the shutter operation is performed, the built-in camera 13 performs shooting based on the shooting signal from the main control unit 20 and outputs a shot image (step S106). The captured image is trimmed to the pixel size of the icon image by the image trimming unit 41, and then a save confirmation screen including the trimmed image is generated by the finder screen generating unit 42 and displayed on the display 11 (step S107, S108).

  Thereafter, if the user performs a confirmation operation, the trimmed image displayed on the save confirmation screen is written as an icon image in the icon image storage unit 32 (step S110). On the other hand, when the user does not agree to data storage, such as when a cancel operation is performed, the trimmed image is discarded and the process is terminated.

  According to the present embodiment, in the camera-equipped mobile phone that can use the captured image of the built-in camera 13 as an icon image, when the icon image is captured, the image trimming unit 41 trims the captured image, and the pixel of the icon image It is converted to a trimmed image consisting of size. For this reason, in order to adjust the pixel size, there is no need for the user to perform complicated operations on the image editing application after shooting. Therefore, even a user who has no knowledge about image processing can easily create an original icon image.

  Further, according to the present embodiment, in the icon image shooting mode, the viewfinder screen is generated based on the trimmed image. For this reason, the display image on the finder screen can be matched with the icon image obtained by shooting. That is, there is no problem that a fine depiction that can be identified on the finder screen disappears from the icon image obtained by photographing. Therefore, the user can generate a desired icon image.

  Further, according to the present embodiment, in the icon image shooting mode, the pixel size of the trimmed image is enlarged to an integral multiple, and a viewfinder screen is generated based on the enlarged trimmed image. For this reason, it is possible to make the viewfinder screen easier to see while matching the amount of information between the display image on the viewfinder screen and the icon image obtained by shooting. In particular, when a shutter operation is performed, the distance from the user's eyes to the display 11 tends to be longer than in other cases. For this reason, by displaying the enlarged image on the viewfinder screen without changing the amount of information, the user can take a desired icon image.

  In addition, according to the present embodiment, after storing the captured icon image in the icon image storage unit 32 after the shutter operation, the trimming image is displayed on the save confirmation screen, and the user is displayed as the icon image. The trimmed image can be viewed under exactly the same conditions as in the case. For this reason, the user can determine whether or not to save the captured icon image (that is, the trimmed image) after confirming the state in which the icon image is actually displayed on the display on the save confirmation screen. .

  Note that the magnification when the finder screen generation unit 42 enlarges the trimmed image is desirably an integer multiple as described above, but the present invention is not limited to such a case. In other words, once the photographed image is trimmed to the pixel size of the icon image and then stretched, even if the magnification is a non-integer multiple (for example, 2.5 times), it is the same as the icon image obtained by photographing for the user. Visible images can be displayed on the viewfinder screen.

Embodiment 2. FIG.
In the first embodiment, an example of a mobile phone that displays a menu screen by linking two icon images to each option as a selection icon and a non-selection icon has been described. On the other hand, in the present embodiment, a case of a mobile phone that links one icon image to each option and displays the combined focus image on the icon image when the focus is applied will be described.

  FIG. 9 is a block diagram showing a configuration example of the main part of the mobile phone according to Embodiment 2 of the present invention, and shows another configuration example of main controller 20 in FIG. 2 (Embodiment 1). ing. Compared to the case of FIG. 3 (Embodiment 1), the difference is that a volatile memory 60 including a selection icon image storage unit 61 is provided. Another difference is that the nonvolatile memory 30 includes a focus image storage unit 34, the imaging processing unit 40 includes a selection iconification processing unit 44, and the menu processing unit 50 includes a selection icon generation unit 53.

  FIG. 10 is a diagram showing an example of the menu information held in the menu information storage unit 31 of FIG. Each sheet shown corresponds to the menu information 80 to 82, and each row in each sheet corresponds to an option. This embodiment is different from the menu information 70 to 72 of the first embodiment in that only one icon image is linked to each option. In the present embodiment, in menu information 80 to 82, an icon image linked to each option is used as a non-selected icon image. That is, in the case of an option that is not focused, the icon image is displayed in the menu screen.

  The selection icon generation unit 53 generates a selection icon image. The selected icon image is generated by combining the focus image with the non-selected icon image. In other words, the selected icon image in focus is generated in the menu processing unit 50 by processing the non-selected icon image.

  The focus image storage unit 34 is included in the nonvolatile memory 30 and holds a focus image. The focus image according to the present embodiment is a still image. The focus image storage unit 34 holds a plurality of focus images, and the focus image used in each menu screen is defined in the menu information. For this reason, the user can also change the focus image. Furthermore, any image data provided by the user can be used as the focus image.

  FIG. 11 is an explanatory diagram showing an example of processing in the selection icon generation unit 53. The icon image used as the non-selected icon is read from the icon image storage unit 32, and the focus image is read from the focus image storage unit. The focus image in the figure is a still image having the same pixel size as the icon image, and has a frame shape surrounding the transparent central portion. The selection icon generation unit 53 generates a selection icon image by combining the focus image as a foreground and the icon image as a background. The selection icon image generated in this way is stored in the selection icon image storage unit 61 in the volatile memory 60 and is used by the menu screen generation unit 52 to generate a menu screen.

  The selection iconification processing unit 44 performs the same processing as the selection icon generation unit 53 on the trimmed image captured by the built-in camera 13 and trimmed by the image trimming unit 41. That is, a selected icon image is generated when a focus image is combined with a trimmed image and the trimmed image is used as a non-selected icon image. The finder screen generation unit 42 generates a finder screen by enlarging the trimmed image that has been converted into the selected icon.

  On the other hand, after the shutter operation, the selection iconification processing unit 44 does not perform selection iconification processing (combination processing), and the saved icon image (that is, the trimmed image) is displayed on the save confirmation screen.

  FIG. 12 is an explanatory diagram illustrating an example of a viewfinder screen and a save confirmation screen when an icon image is captured. In the viewfinder screen shown in (a) in the figure, the focus image is synthesized and displayed, so that compatibility with the focus image can be confirmed at the time of shooting. For example, when the color of the frame-shaped focus image and the color of the trimming image are similar, the difference between the selected icon image and the non-selected icon image becomes difficult to distinguish. Such a problem can be avoided during shooting. On the other hand, on the save confirmation screen shown in (b), as in the case of the first embodiment, a trimmed image with no synthesized focus image is displayed.

  Steps S201 to S211 in FIG. 13 are flowcharts showing an example of icon image shooting processing according to the second embodiment of the present invention. Compared to FIG. 8 (Embodiment 1), the only difference is that step S203 is added. That is, the focus image is synthesized after trimming the captured image captured by the monitor (step S203).

  According to the present embodiment, in a mobile phone in which a selection icon image obtained by synthesizing a focus image with an icon image is displayed for an option that is focused on the menu screen, the selection icon is converted into an icon image in the shooting mode. The processing unit 44 combines the focus image with the trimmed image of the photographed image, and displays the selected icon image on the viewfinder screen. For this reason, the user can take an icon image while looking at the viewfinder screen and confirming compatibility with the focus image.

Embodiment 3 FIG.
In the second embodiment, an example in which a still image is adopted as a focus image has been described. On the other hand, in this embodiment, a case will be described in which a moving image composed of a plurality of still images is employed as a focus image.

  In the present embodiment, the focus image storage unit 34 holds a set of four still images (frame images) as the focus image. That is, the focus image is composed of a moving image composed of four frames.

  The selection icon generation unit 53 combines a focus image as a moving image read from the focus image storage unit 34 with an icon image as a still image read from the icon image storage unit 32 to generate a selection icon image as a moving image. Yes. That is, each frame image constituting the focus image is synthesized with one icon image to generate four still images. A moving image using the four still images generated in this way as frame images becomes the selection icon image in the present embodiment and is stored in the selection icon image storage unit 61.

  When the selected icon image becomes a moving image, the required memory resource increases as compared with the second embodiment in which the selected icon image is a still image. For this reason, if a selection icon image is generated in advance for each option, limited memory resources cannot be effectively used, leading to an increase in the cost of the mobile phone. For this reason, the selection icon generation unit 53 always holds only the selection icon image of one option that is focused.

  The menu screen generation unit 52 reads the four frame images from the selection icon storage unit 61 and sequentially displays them at the same position on the menu screen, thereby displaying the selection icon as a moving image. In this case, since there are only four frame images, the repetition operation is four frames. Note that the fixed period after the focus is moved may be a moving image display period in which the selected icon is displayed as a moving image, and then any one of the frame images may be displayed to stop the movement of the selected icon. In this case, current consumption accompanying screen display can be suppressed.

  FIG. 14 is an explanatory diagram showing an example of processing in the selection icon generation unit 53. Each frame image constituting the focus image in the figure is a still image having the same pixel size as the icon image, and a star figure is drawn in a part of a transparent area. Each frame image has a different star arrangement. By sequentially displaying these frame images, the star appears to move. By synthesizing these frame images as the foreground and the same icon image as the background, each frame image constituting the selected icon image is generated. By sequentially displaying each frame image generated in this manner, a moving image in which stars move around in front of the icon image is displayed.

  The selection iconification processing unit 44 performs the same processing as the selection icon generation unit 53 on the trimmed image captured by the built-in camera 13 and trimmed by the image trimming unit 41. That is, a selection icon image is generated when the trimming image is a non-selection icon image. At this time, by sequentially synthesizing frame images with sequentially input trimmed images, a focus image as a moving image can be synthesized and an expanded trimmed image can be displayed on the finder screen. it can.

  Note that the composition processing in the selection iconification processing unit 44 may be performed using any one frame image constituting the focus image. That is, the frame image may be used as a still image focus image, and the selection iconification processing unit 44 may perform the same synthesis process as in the second embodiment. In this case, the user can view the selected icon image on the viewfinder screen when the moving image display period has elapsed after the focus movement.

  According to the present embodiment, in a mobile phone in which a selection icon image obtained by combining a focus image of a moving image with an icon image is displayed for an option that is focused on the menu screen, the user is in the icon image shooting mode. The icon image can be taken while checking the compatibility with the focus image of the moving image by looking at the finder screen.

  In the present embodiment, an example in which the focus image is composed of four frame images has been described. However, the present invention is not limited to such a case. That is, the focus image can be composed of two or more arbitrary number of frame images.
