Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In the present embodiment, the case where the image display device is mounted on a mobile phone, which is a kind of mobile information processing terminal, is illustrated, but the mounted device is not limited to the mobile information processing terminal, and is a stationary type such as a computer. It may be mounted on the device.

(Constitution)
FIG. 1 is a block diagram of a mobile phone on which the image display apparatus according to this embodiment is mounted. Referring to FIG. 1, mobile phone 100 includes a storage unit 110 including an antenna 151 and a wireless device 15 for communication, a ROM (Read Only Memory) and a RAM (Random Access Memory) for storing programs and data, and the like. , An operation unit 140 operated to receive an instruction from a user, a CPU (Central Processing Unit) 120, a display panel 160, and a display driver 130 for controlling the display panel 160 to display an image.

  The storage unit 110 includes an image storage unit 1 for storing various image data of still images and moving images, a bail view template storage unit 2 for storing bail view information, a self-made bale view storage unit 3, and a bale view pattern. A storage unit 4 and a download bale view storage unit 5 are included.

  The bail view template storage unit 2 stores a template of bale view information in advance. The self-made bale view storage unit 3 stores bale view information created by the user himself / herself or by operating the operation unit 140 using a template in the bail view template storage unit 2. The download bale view storage unit 5 stores bale view information downloaded from an external device via a communication line (not shown) such as the Internet and the wireless device 15.

  The operation unit 140 includes a touch panel unit 6A configured integrally with the display panel 160 and a key unit 6B including a plurality of keys.

  FIG. 2 shows the configuration of the display unit according to the present embodiment. The display unit includes the display driver 130 and the display panel 160 of FIG. Referring to FIG. 2, display panel 160 includes a backlight 400 as a display light source, a diffusion plate (not shown) that uniformly diffuses white light emitted from backlight 400, and a liquid crystal layer on two substrates. A plurality of liquid crystal panels 330, 331, 332, and 333 having a configuration sandwiched between them. In order to enable stereoscopic viewing, a plurality of liquid crystal panels are stacked in layers with an interval (distance) based on parallax with the display surface parallel.

  The display driver 130 is provided corresponding to each of the control unit (not shown) of the backlight 400 and the liquid crystal panels 330, 331, 332, and 333, and is a liquid crystal for controlling the operation of the corresponding liquid crystal panel. Drivers 140, 141, 142, and 143 are included. Here, since each of liquid crystal panels 330, 331, 332, and 333 has the same configuration and function, they may be collectively referred to as a liquid crystal panel. In addition, since each of the liquid crystal drivers 140, 141, 142, and 143 has the same configuration and function, they may be collectively referred to as a liquid crystal driver.

  In the present embodiment, when each of the liquid crystal panels 330, 331, 332, and 333 stacked in layers is divided as a layer, the depth is 0 layer and the depth in order from the liquid crystal panel positioned on the surface side of the display panel 160. These are referred to as 1 layer, 2 depth layers, and 3 depth layers. Here, “depth” refers to the distance from the eye of the user viewing the display panel 160 from the front direction to the image displayed on the liquid crystal panel in the direction of arrow R. Therefore, an image to be displayed in the distance is displayed in, for example, the depth 3 layer, and an image to be displayed in the vicinity is displayed in, for example, the depth 1 layer. It can be brought to stereoscopic view.

  The liquid crystal panel has two substrates made of a glass material, and both substrates sandwich (seal) a liquid crystal layer therebetween. On the liquid crystal layer side of both substrates, a thin film transistor (TFT) which is a switching element, a pixel electrode, a bus wiring, an alignment film, a black matrix (BM) and the like are provided as constituent elements of a display element of the liquid crystal panel. That is, one substrate is a so-called TFT array substrate, and the other substrate is a so-called color filter substrate (CF substrate). Thus, the liquid crystal panel is an active matrix type liquid crystal panel in which pixels are arranged in a matrix.

  The TFT array substrate includes a glass material substrate, a plurality of TFT elements formed on the substrate, a pixel electrode connected to the drain electrode of the TFT element, and a polarizing plate disposed on the back surface of the substrate. Including. The CF substrate is a glass material substrate, a color filter formed on the main surface of the substrate facing the TFT array substrate, a shared electrode formed on the color filter, and a substrate disposed on the substrate. A polarizing plate. In operation, the liquid crystal panel controls the arrangement of the liquid crystal molecules in the liquid crystal layer by applying a predetermined voltage according to the image data from the corresponding liquid crystal driver to the pixel electrode and the shared electrode, respectively. The transmission of light from the light 400 is controlled. In this case, a voltage is applied to a partial pixel of the display panel 160 where a layer 0 image, for example, is not displayed, so as to transmit light from, for example, the layer 1 liquid crystal panel below it. As a result, the light transmitted through the layer 1 pixel corresponding to the partial pixel passes through the layer 0 and enters the eye of the observer. Thereby, even if an image is displayed on a different layer, a display image of a different layer can be confirmed simultaneously.

  In the present embodiment, a 2D image can be displayed on the display panel 160. A mechanism for displaying a 2D image on the display panel 160 will be described. In this case, the 2D image read from the image storage unit 1 of the storage unit 110 by the liquid crystal driver 143 is displayed on the liquid crystal panel of the same layer among the plurality of layers, more preferably the liquid crystal panel 333 of the depth 0 layer. Thereby, the observer can observe a 2D image, that is, a planar image.

  In the present embodiment, the user can input a switching instruction for switching an image displayed on the display panel 160 to either a 3D image or a 2D image by operating the operation unit 140. When a 3D image display is instructed by a switching instruction, a 3D image is displayed. When a 2D image display is instructed, a 2D image is displayed.

  Returning to FIG. 1, the configuration of the CPU 120 will be described. The CPU 120 has a function for displaying the 2D image and the 3D image of the image storage unit 1 on the display unit. Here, a case where a 3D image is displayed for the sake of simplicity will be described. In the present embodiment, 3D image data refers to image data for stereoscopic viewing by displaying images on liquid crystal panels at different depths. When displaying on a single liquid crystal panel, the image data is recognized as a 2D image.

  The CPU 120 includes a bail view setting unit 7, a 3D image decomposition control unit 8, a 3D image recognition unit 9, a 3D application control unit 16, and a 3D image composition control unit 13.

  The bale view setting unit 7 reads the bale view information from any one of the bail view template storage unit 2, the self-made bale view storage unit 3, the bail view pattern storage unit 4, and the download bail view storage unit 5, and outputs it to the decomposition control unit 8 To do.

  Based on the 3D image data read from the image storage unit 1 and the bale view information input from the bail view setting unit 7, the decomposition control unit 8 sets the 3D image data at different depths according to the pattern indicated by the bail view information. Divide into multiple image data to be displayed. In order to simplify the explanation, it is assumed that the pattern indicated by the bail view information is a checkered pattern.

  The decomposition control unit 8 decomposes the 3D image data into a checkered pattern so that the image data 10 to be displayed on the liquid crystal panel with a depth of 1 layer from the 3D image data and the image to be displayed on the liquid crystal panel with a depth of 2 layers. The data 11 is divided. For example, when the checkered lattice is divided into two colors of black and white, it is divided into image data 10 of a white area and image data 11 of a black area.

  Depending on the pattern indicated by the bail view information, image data 12 to be displayed on a liquid crystal panel having another depth, for example, a depth of 3 layers, may be output due to the division. Here, to simplify the description, it is assumed that the 3D image data is divided into image data 10 and 11.

  The image data 10 and 11 are given to the composition control unit 13. The composition control unit 13 synthesizes the image data 10 and 11 and outputs image data acquired by the composition (hereinafter referred to as composite image data) to the display unit. Specifically, the composition control unit 13 adds “layer data” that instructs which of the depth 0 layer to the depth 3 layer to display for each of the image data 10 and 11, and the operation unit The composite image data is acquired by including the “3D switching instruction” input from 140.

  Based on the “layer data” corresponding to each of the image data 10 and 11, the display driver 130 determines a liquid crystal driver to which the image data is to be applied, and outputs image data corresponding to the determined liquid crystal driver. Here, a table associating each depth from the depth 0 layer to the depth 3 layer with information indicating the liquid crystal driver that drives the liquid crystal panel of the layer is stored in the storage unit 110 in advance. Therefore, the display driver 130 can determine the liquid crystal driver to which the image data 10 and 11 are to be provided by searching the table based on the “layer data” of the composite image data.

  In this case, by searching the table, the display driver 130 gives the image data 10 to the liquid crystal driver 142 and gives the image data 11 to the liquid crystal driver 141. The liquid crystal driver 142 displays an image according to the image data 10 by applying a voltage to the pixel electrode and the common electrode of the liquid crystal panel 332 according to the image data 10. Further, the liquid crystal driver 141 displays an image according to the image data 11 by applying voltages to the pixel electrode and the common electrode of the liquid crystal panel 331 according to the image data 11.

(Image display by pattern division)
FIG. 3 is a diagram illustrating a display image for explaining a method for realizing a bail view according to the composite image data. FIG. 3A shows a display image 101 based on the original 3D image data. In the present embodiment, a bale view is realized by using layers having different “depths” for expressing the pop-up and depth of display described in FIG. 2 for the 3D image data. In FIG. 4, it is a figure which illustrates typically the state which confirms the display image of the display panel 160 from a different viewpoint.

  3B and 3C show a display image 102 according to the image data 10 by the liquid crystal panel 332 and a display image 103 according to the image data 11 by the liquid crystal panel 331. Here, the decomposition control unit 8 does not divide the 3D image data into a slit shape, but divides the 3D image data into a checkered lattice shape according to the bale view information, so that 2D to be displayed at different depths from the original 3D image data. One image data is generated. The two image data are both processed so that the vertical information and the horizontal information of the original 3D image data become 1/2. In other words, the images 102 and 103 according to the two image data are divided so that a display image 104 can be obtained so that the entire original image can be confirmed when superimposed and synthesized as shown in FIG. Done. As a result, the images 102 and 103 are displayed, so that the user who observes the display image in the direction of the arrow R in FIG. A sense of depth based on the amount of parallax set according to depth is given.

  On the other hand, when observing an image from a direction other than the front direction, the image is formed on the viewer's eyes as if the image is shifted due to the interval between the liquid crystal panels. That is, in the case of stereoscopic viewing using a conventional parallax barrier, each of the two images (left-eye image and right-eye image) is only halved in the horizontal direction due to the vertical slit division. In the present embodiment, the information is reduced in both the vertical direction and the horizontal direction by dividing the checker pattern. Therefore, when the image 102 and the image 103 in FIG. 3E are displayed at the same time, from the viewpoint of Mr. A in FIG. 4 who looks at the display panel 160 from the front direction, as shown in FIG. The image can be observed. On the other hand, when viewing from the right side of the display panel 160 (the viewpoint of Mr. B in FIG. 4), the image 105 in a state where a part of the image 103 on the left side is combined and the image is partially lost is observed. Will do. When viewing the display image from the left direction from the viewpoint of Mr. C in FIG. 4, the display image looks the same as Mr. B viewed from the right direction. In FIG. 3, the colors are darkened so that the checkerboard-like screen division can be easily understood, but the actual hues are the same.

  FIG. 5 is an image diagram showing an enlarged state of a part of the display image 104 in FIG. 3D when performing the bail view by pattern division. FIG. 5A shows an enlarged view of the depth 1 layer display image 102 and the depth 2 layer display image 103 in this portion. 5A shows an image of the partial image of the display image 104 viewed from the front direction of the display panel 160. FIGS. 5B and 5C show the partial image in the right direction of the display panel 160. FIG. Images respectively viewed from the left side are shown, and FIG. 5D shows an image of the portion viewed from the diagonal left side.

  As shown in the figure, by displaying each of the images divided according to the checkered lattice pattern on the liquid crystal panels of different layers, the display images of different layers overlap each other like the portion 301 depending on the direction (angle) of viewing the display panel 160. The part where the image appears to be dark due to such a shift and the display image of different layers, such as the part 401, do not overlap each other and do not overlap, and there is a gap, and no part of the image appears to be displayed in the gap Will occur. Thus, by using the difference in depth, it becomes possible to form a correct image (display image 104) that does not include the portions 301 and 401 on the eyes of the person who observed the display panel 160 from the front direction. An image including portions 301 and 401 is formed as shown in FIGS. 5B to 5D on the eyes of a person observed from another direction other than the front direction, and the display image 104 is confirmed. I can't do that. As a result, a person who views the display panel 160 from a direction different from the front direction can perform a bale view on the display image 104, thereby preventing peeping.

(Change of image size due to depth difference)
FIG. 6 is a diagram schematically illustrating a procedure for changing the size of the display image in accordance with the difference in depth. When the image is divided in the above-described checkered lattice pattern, the display image 104 is shown in FIG. 6A as the depth difference between the layers on which the image 102 and the image 103 acquired by the division are increased. As described above, the gap between the adjacent images 102 and 103 is increased. As the depth difference increases, this gap becomes prominent even when observed from the front direction of the display panel 160.

  Therefore, in this embodiment, in order to improve the visibility of the display image 104 from the front direction while maintaining the peeping prevention effect, the gap is supplemented with an image (see FIG. 6B). The display image size changing process is performed by the size changing unit 131 of the composition control unit 13. In FIG. 6B, the image 103 displayed on the liquid crystal panel having a greater depth is changed to an image 103A by increasing its size. Thereby, it is possible to prevent the visibility of the display image 104 from being lost by supplementing the gap due to the depth difference with the image 103A whose size has been enlarged.

  FIG. 7 is a process flowchart for performing a bale view including an image size change due to a depth difference according to the present embodiment. A program according to this flowchart is stored in the storage unit 110 in advance, and the CPU 120 reads out the program from the storage unit 110 and executes the program, thereby realizing a veil view.

  Note that an adjustment value table 132 is stored in the storage unit 110 in advance for changing the image size. The adjustment value table 132 stores adjustment values corresponding to a plurality of types of depth differences, which are intervals between a plurality of liquid crystal panels stacked in layers, and the depth differences. The adjustment value indicates a value (for example, 105%, 110%, etc.) indicating how much the image should be enlarged when the size of the image to be enlarged is 100%, and is acquired in advance by an experiment. .

  In operation, the bail view setting unit 7 reads bale view information designated by the user from the storage unit 110 via the operation unit 140, and outputs the bail view information from the disassembly control unit 8 (step S59).

  The decomposition control unit 8 divides the 3D image into image data 10 and image data 11 based on the 3D image read from the image storage unit 1 and the bail view information input from the bail view setting unit 7. And 11 are given to the composition control unit 13, and the composition control unit 13 obtains composite image data (step S60).

  When the image data 10 and 11 are given to the composition control unit 13, the size changing unit 131 uses the image data 10 and 11 based on the “layer data” added to the image data 10 and 11 by the composition control unit 13. It is determined whether or not there are two or more layers to be displayed, that is, whether the depth difference between the two layers is two or more (step S61).

  If it is determined that the distance is not two or more (NO in step S61), the process proceeds to step S65, and the combined image data by the combining control unit 13 is output to the display unit as it is (step S65).

  On the other hand, if it is determined that the distance is two or more (YES in step S61), the adjustment value table 132 is searched based on the depth difference between both layers. By the search, the adjustment value corresponding to the depth difference is read from the adjustment value table 132 (step S62).

  The size changing unit 131 is based on the “layer data” added to the image data 10 and 11 in the composite image data, and the image data 10 and 11 has a larger depth (that is, from the surface of the display panel 160). Image data to be displayed on the farther layer is selected, and the selected image data is enlarged to a size based on the adjustment value read in step S62 (step S63). In FIG. 6, the image data of the image 103 is enlarged. Thereafter, composite image data including the enlarged image data is output to the display unit.

  Note that in this embodiment, an interpolation method that gives an estimated pixel between source pixels is applied to the image enlargement process, but the method to be applied is not limited to this method.

(Veil view emphasis setting)
FIG. 8 is a process flowchart for acquiring the bale view enhancement designation method according to the present embodiment. A program according to this flowchart is stored in the storage unit 110 in advance, and the CPU 120 reads the program from the storage unit 110 and executes it.

  There are two types of bail view enhancement methods, “touch detection enhancement” and “human detection enhancement”, and either method can be designated in advance from the operation unit 140. “Touch detection enhancement” is a method in which when the user wants to effectively hide a partial image in an image on which the bail view is performed on the display panel 160, the partial image is designated and operated on the touch panel unit 6A. This function emphasizes the bale view effect on images. “Human detection enhancement” is a function for enhancing the bale view effect on a partial image when it is determined that the 3D image to be subjected to the bail view includes a partial image that is a human image.

  Referring to FIG. 8, the bail view setting unit 7 determines a bail view enhancement method designated in advance by the user based on the operation of the operation unit 140 (step S32). The determination result is stored as emphasis designation data 72 in the storage unit 110. The enhancement designation data 72 is assumed to have “touch detection enhancement” set as an initial value.

  If the result of determination is “touch detection emphasis”, the bail view setting unit 7 sets “touch detection emphasis” in the emphasis designation data 72 of the storage unit 110 (step S33), and determines “human detection emphasis”. The bale view setting unit 7 sets “human detection enhancement” in the enhancement designation data 72 (step S34). Thereby, the bale view enhancement method desired by the user can be acquired.

  FIG. 9 is a flowchart of the bale view enhancement process when the touch detection enhancement according to the present embodiment is designated. A program according to this flowchart is stored in the storage unit 110 in advance, and the CPU 120 reads the program from the storage unit 110 and executes it. Here, it is assumed that “touch detection enhancement” is set in the enhancement designation data 72.

  First, as shown in FIG. 3D, the display panel 160 displays the image 104 having the bale view effect (step S41). When the user operates the touch panel unit 6A and touches a desired portion of the display panel 160, the touch position is detected as a coordinate value on the surface of the display panel 160 by the display driver 130, and the detected coordinate information is output to the CPU 120. (Step S42).

  On the display panel 160, an image in which the bale view effect of the image of the touched portion of the user is emphasized more than the other portions is displayed (step S43). Specifically, the decomposition control unit 8 specifies a partial pattern corresponding to the coordinate in the pattern indicated by the bail view information input from the bail view setting unit 7 based on the coordinate information, and the checkered lattice of the specified partial pattern Is changed (edited) so that the pattern density becomes higher than other portions, that is, the pattern becomes finer, and the original 3D image is divided into image data 10 and 11 using the checkered lattice pattern after the change. The composite image data including the image data 10 and 11 is generated and output to the display unit. As a result, the display panel 160 displays an image in which the bale view effect of the image touched by the user is more emphasized than the other portions.

  Thereafter, when the display driver 130 detects that the user has lifted the finger touched from the display panel 160 based on a signal generated by operating the touch panel unit 6A (step S44), the detection signal is output to the CPU 120.

  The original image having the veil view effect before the user touches the display panel 160 is restored (displayed) (step S45). Specifically, the decomposition control unit 8 divides the original 3D image into image data 10 and 11 using a pattern indicated by the bail view information input from the bail view setting unit 7, and the image data 10 and 11. Is generated and output to the display unit. As a result, the display panel 160 displays an image that exhibits the bale view effect before the user touches (before the bale view effect is emphasized).

  Assuming that the user removes the finger touched from the display panel 160, the composite image data composed of the image data 10 and 11 having the veil view effect before the user touches is saved in the storage unit 110. You may leave it. When it is detected that the finger that has been touched is released, if the saved composite image data is read from the storage unit 110 and output to the display unit, the image is divided and combined by the decomposition control unit 8. Generation of the composite image data by the unit 13 can be omitted.

  Next, when “human detection enhancement” is set in the enhancement designation data 72, the bale view effect is enhanced as follows.

  When reading the 3D image data from the image storage unit 1, the bail view setting unit 7 activates the image recognition unit 9 based on the emphasis designation data 72. The image recognition unit 9 recognizes a human face image in 3D image data. Specifically, 3D image data is subjected to pattern matching processing using pattern data representing facial features, and an image of a portion having a high similarity to the pattern data is determined as a face image. Position coordinate information corresponding to the face image in the 3D image data is acquired and output to the decomposition control unit 8. Note that the face image determination method is not limited to this.

  Based on the coordinate information, the decomposition control unit 8 specifies a partial pattern corresponding to the coordinate in the pattern indicated by the bail view information input from the bail view setting unit 7 so that the checkered lattice of the specified partial pattern becomes fine. The original 3D image is divided into image data 10 and 11 using the edited checkered pattern, and composite image data including the image data 10 and 11 is generated and output to the display unit. As a result, the display panel 160 can display an image in which the bale view effect on the human face image is emphasized more than other portions.

  As described above, with respect to the touched partial image or the human image of the 3D image, the desired partial image or the human image can be peeped by emphasizing the veil view effect over the other partial images. It can be effectively prevented.

(Veil view settings by application)
In the present embodiment, when a phone book application (program) is started, a bale view is performed on a partial image that is not desired to be shown in the 3D image displayed by the program. FIG. 10 shows a state in which the veil view is performed only on the phone number image among the display images of the phone book data according to the present embodiment.

  FIG. 11 is a process flowchart for setting a partial image on which a bail view is to be performed in the display image of the selected application according to the present embodiment. A program according to this flowchart is stored in the storage unit 110 in advance, and the CPU 120 reads the program from the storage unit 110 and executes it.

  When the user operates the operation unit 140 to select the application-based bail view function, the CPU 120 activates the 3D application control unit 16 based on an instruction according to the operation.

  The 3D application control unit 16 selects an application based on a user operation of the operation unit 140 (step S51). Here, the address book application, the schedule book application, and the gallery application program and data (address book data, schedule book data, gallery data) are stored in advance in the storage unit 110, and any one of them is stored. Is selected (steps S52, S53, S54). It is assumed that name, address, telephone number, FAX (facsimile) number, etc. are registered in the address book data.

  For example, when an address book application is selected, the 3D application control unit 16 performs information (for example, name, address, telephone number, FAX number) designated to perform the bale view based on the operation of the user operation unit 140. Is selected (step S55). For example, assume that a telephone number is selected.

  The 3D application control unit 16 acquires coordinate information that is the display position of the selected information (phone number) in the display image by the address book application (step S56). Thereby, information for performing the bail view is set only on the partial image of the selected information in the display image by the address book application.

  Thereafter, when the address book application is activated and the image of FIG. 10 is displayed, the 3D application control unit 16 generates 3D image data in a predetermined procedure based on the address book data read from the storage unit 110. Then, the generated 3D image data and the coordinate information (positional coordinate information of the telephone number image) acquired in step S56 are output to the decomposition control unit 8.

  The decomposition control unit 8 applies the checkered lattice pattern only to the partial image indicated by the coordinate information based on the coordinate information from the 3D application control unit 16, the 3D image data, and the bale view information from the bail view setting unit 7. The 3D image data is divided into depth 1 image data 10 and depth 2 image data 11. Thereby, only the partial image indicated by the coordinate information in the image of the 3D image data is divided into two images having different depths according to the checkered lattice pattern, and the image of the other region of the image of the 3D image data is not divided. The division is performed so that only one depth (for example, depth 1) is displayed.

  The image data divided in this way is output to the display unit via the synthesis control unit 13 and displayed on the display panel 160 (see FIG. 10).

(Obtain bale view information)
FIG. 12 is a flowchart of bale view information acquisition processing according to the present embodiment. A program according to this flowchart is stored in the storage unit 110 in advance, and the function of the bail view setting unit 7 is realized by the CPU 120 reading and executing the program from the storage unit 110. A process for selecting and acquiring bale view information to be used by a user operation will be described with reference to the flowchart of FIG.

  When the user operates the operation unit 140 to select the bail view setting function, the bail view setting unit 7 displays the bail view information options to be used on the display panel 160 (step S11). Options include, for example, “template”, “download from network”, and “create user”. The user operates the operation unit 140 to select a desired option.

  When “template” is selected (step S12), the bail view setting unit 7 reads the bail view information to be used from the bail view template storage unit 2 (step S21). Thereby, the bale view information to be used is determined.

  When “download from the network” is selected (step S13), the bail view setting unit 7 accesses the home page of the predetermined server device via the wireless device 15 (step S15), and selects desired bail view information from the home page. Then, the selected bale view information is downloaded and stored in the download bale view storage unit 5 of the storage unit 110 (step S20). The bail view setting unit 7 reads the bail view information to be used from the download bale view storage unit 5 (step S21). Thereby, the bale view information to be used is determined.

  The user can also create desired bale view information. When “user creation” is selected by the user via the operation unit 140 (step S14), the bail view setting unit 7 reads a bale view pattern as a template from the bail view template storage unit 2 and displays it on the display panel 160. . The user operates the operation unit 140 to select a desired template (step S17).

  The user operates the operation unit 140 to edit the selected template into a desired bale view pattern. Based on the user operation from the operation unit 140, the pattern creation unit 71 of the bail view setting unit 7 creates a user-desired pattern, for example, by changing the number of pattern patterns and the pattern size (step S18, S19). Specifically, when the template is a checkered grid pattern, the number and size of grid grids are changed. As a result, a pattern for bale view desired by the user for peeping prevention is created from one template.

  The bale view setting unit 7 stores the bale view information of the created pattern in the self-made bale view storage unit 3 (step S20). The bail view setting unit 7 reads the bail view information to be used from the self-made bale view storage unit 3 (step S21). Thereby, the bale view information to be used is determined.

(Example of bale view information)
The pattern that can be used as the bale view information is not limited to the checkered lattice pattern described above. For example, even when the image data 10 and 11 are divided in the left pattern of FIG. 13, when the display panel 160 is viewed from the right side or the left side instead of the front direction, the image data 10 and the right side of FIG. A gap can be generated between the 11 images, and a bale view effect can be obtained.

  Further, as shown in FIGS. 14 and 15, star-shaped and round-shaped patterns can be used. By touching a partial image that is not desired to be seen in FIG. 15, the above-described “touch detection emphasis” function can be used to make the pattern complicated.

Such a program is a memory medium (memory-shaped card, flexible disk, CD (Compact Disc) -ROM, ROM, RAM, etc.) attached to the mobile phone, and is recorded on a recording medium readable by the CPU 120. It can also be provided as a program product. Alternatively, the program can be provided by downloading to a predetermined storage area of the mobile phone received by the wireless device 15 via the network.
