The image projection unit 130 includes a beam light source 131, an optical scanner 132, and a drive control unit 133 for driving them. As the beam light source 131, an LD (semiconductor laser), an LED (light emitting diode), or the like can be used. The intensity of the beam light emitted from the beam light source 131 is controlled by the drive control unit 133 based on the control data sent from the control unit 111. The optical scanner 132 is an optical device that projects the beam light emitted from the beam light source 131 onto the projection surface 200 while scanning two-dimensionally. The scanning of the beam light by the optical scanner 132 is driven and controlled by the drive control unit 133 as in the case of the beam light source 131.

The image projection unit 130 also serves as a light source for the first image projection unit, one of the two displays 119a and 119b constituting the image display unit 119 of the mobile phone.
The image displayed on the rear display 119b is projected onto the projection plane 200 by the enlargement projection optical system 136 as shown in FIG. The enlarged projection optical system 136 is configured to be detachable from the mobile phone body 100. Normally, it is detached from the mobile phone main body 100, and when used for image projection, it can be mounted on the rear display 119b of the mobile phone main body 100 by mounting fixing portions 136a provided at both ends.
Further, when the image of the rear display 119b is projected as shown in FIG. 5, it is preferable that the control unit 111 controls the light amount of the rear display 119b to be higher than that during normal image display. In this case, the visibility of the projected image can be improved.
In the configuration example of FIG. 6, the second image projection unit 140 is provided on the upper surface of the mobile phone main body 100 so that an image can be projected upward.

  Further, in the configuration of FIG. 5, there is a case where a projection optical system 136 that projects the image of the rear display 119b by reversing left and right is used. In this case, at the time of image projection, the image is displayed on the rear display 119b while being horizontally reversed from that at the time of normal image display. As a result, an image such as character information can be projected in the same right and left direction as in normal image display.

Note that the configurations of the image projection units 130 and 140 are not limited to the configurations of FIGS. 3, 4, and 5. For example, the structure which projects using a hologram element may be sufficient.
The image may be projected at a wide angle. For example, the entire inner wall surface of the room may be viewed on the projection surface and the image may be projected at a wide angle. In this case, for example, an incoming call notification with an unprecedented taste can be made so as to project an image of the sky where the starry sky glitters over the entire room like a planetarium.

FIG. 1 is an explanatory diagram showing a state in which a plurality of images are projected by the foldable mobile phone 100 including the image projection units 130 and 140. In the standby state, the mobile phone 100 is placed on a desk with the light exit ports of the image projection units 130 and 140 facing the desired projection surfaces 200 and 210, respectively, or set in a charger for the mobile phone. Keep it. In addition, the user operates the key operation unit 120 to set one of a normal image display mode in which image projection is not performed and an image projection mode in which image projection is performed. The mobile phone 100 according to the present embodiment is configured such that different images can be projected onto the projection plane 200 and the projection plane 210, respectively, when the image projection mode is executed. In the example of FIG. 1, an incoming call notification image or a standby image is projected on the first projection plane 200, and the received mail text or distribution information is projected on the second projection plane 210 as character information.
Further, while projecting a standby image onto the first projection plane 200, an image of an application program for a game being executed on the mobile phone may be projected onto the second projection plane 210. If the game application program uses two images, the first image is projected onto the first projection plane 200 and the second image is projected onto the second projection plane 200 at the same time. You may make it do. Further, the image of character information may be projected by the first image projection unit, and the above-described sky image may be projected on the entire room by the second image projection unit.

  As described above, according to the present embodiment, the two image projection units 130 and 140 controlled by the control unit 111 project images onto different projection planes 200 and 210, and a plurality of images are projected onto two different projection planes 200. , 210 can be projected simultaneously.

  In the above embodiment, the plurality of image projecting units 130 and 140 may be configured so that a user can arbitrarily switch and project an image. For example, an image can be projected by one of the image projection units 130 and 140, or an image can be projected by both the image projection units 130 and 140. The image projection unit can be specified by the user operating the key operation unit 120 as a specifying unit. The control unit 111 controls to project an image only for the designated image projection unit.

Moreover, in the said embodiment, you may comprise so that a user can change the setting of the light quantity of the said image projection parts 130 and 140 and the back display 119b arbitrarily, and can project an image. For example, when the surface state of the projection surface is difficult to see the projected image or when the projection surface is in a bright environment, the light amount is set to be high. On the contrary, when the surface state of the projection surface is a state in which the projection image is easily visible or when the projection surface is in a dark environment, the light amount is set low. Thereby, it is possible to set an appropriate light amount according to the type of the projection surface and the like, and to suppress wasteful power consumption while ensuring the visibility of the projection image.
Further, the setting of the light amount of the image projection units 130 and 140 and the rear display 119b may be automatically switched to a predetermined light amount when the control unit 111 activates the image projection unit and starts image projection. .

  In the above embodiment, the case where the two image projection units 130 and 140 are provided has been described. However, the present invention can also be applied to a case where three or more image projection units are provided.

  Moreover, in the said embodiment, you may comprise so that the two image projection parts can be arrange | positioned so that it can project in the same direction, and the three-dimensional image | video by an illusion effect can appear. In this case, it can function as a parallax type stereoscopic display.

  In the above embodiment, when there is no image to be projected, the operations of the image projecting units 130 and 140 are stopped, and when the control unit 111 receives an image projection command from the outside or the timing of image projection. It may be controlled to start the image projection by activating the image projection units 130 and 140 when judged. In this case, when the image projection is not performed, the operation of the image projection units 130 and 140 is stopped so that the image projection units 130 and 140 do not consume unnecessary power. Therefore, wasteful power consumption by the image projection units 130 and 140 when no image projection is performed can be prevented, and consumption of the battery in the mobile phone 100 can be prevented.

  Further, the mobile phone 100 according to the above embodiment may be configured to be able to execute an application program developed by object-oriented programming independent of the platform. Then, the activation of the image projection units 130 and 140 and the image projection operation by the image projection units 130 and 140 may be executed based on a command from an application program. Examples of the application program include application programs written in a program language such as JAVA (registered trademark), C, and C ++. The execution environment of these application programs is constructed by middleware such as JAVA (registered trademark) VM or BREW (registered trademark). This application program may be preinstalled in the mobile phone 100, or may be downloaded from a download server via a mobile phone communication network as a communication network, stored in the mobile phone 100, and registered. .

FIG. 7 is a block diagram illustrating an example of a schematic configuration of a mobile phone capable of executing an application program, and FIG. 8 is an explanatory diagram illustrating an example of a software structure in the mobile phone. This cellular phone includes an application program execution management unit 150 as application program execution management means for managing the execution environment of the application program, in addition to the control unit 111 and the like described above. The application program execution management unit 150 includes a system bus, a CPU, a RAM, and the like, and operates according to predetermined middleware for executing the application program. The application program execution management unit 150 corresponds to the central “program execution environment” in the software structure of FIG. 8, and includes a class library, an execution environment management library, an application used for an application program developed by object-oriented programming. Software such as management is provided, and the execution environment of application programs is managed.
Here, the application program can be used by calling a class library such as a function in the program execution environment via a class library API (application interface). The call history of a class library such as this function is held until the virtual execution environment (virtual machine: VM) of the application program is terminated. The execution environment management library in the program execution environment can be used by calling a telephone platform library in the telephone platform described later via the telephone platform API.
The image projection control is performed by sending a control command from the application program execution management unit 150 to the image projection units 130 and 140 via the control unit 111. In addition, as indicated by a broken line in FIG. 7, the application program execution management unit 150 may execute the control command directly by sending it to the image projection unit 130.

In the mobile phone configured as described above, when an image is projected during execution of a standby application program or an application program such as a game, a predetermined instruction for image projection activation request command is issued from the application program to the application program execution environment. Make a function call. Upon receiving this function call, the application program execution environment sends an image projection activation request command to the control unit 111. Upon receiving this image projection start request command, the control unit 111 sends the start request command and image projection control data to the image projection units 130 and 140.
Each of the image projecting units 130 and 140 is activated in response to the activation request command, and starts projecting a predetermined image specified by the control data based on the image projection control data.

  Note that the application program for starting the image projecting units 130 and 140 and executing the image projecting operation may be a standby application program for projecting the incoming notification image, or other application specialized for controlling the projector function, for example. It may be a program.

  Further, in each of the above-described embodiments, an identifier for identifying whether or not the image data is projected only on the image projection units 130 and 140 may be added. Then, the identifier data added to the content data of the image is analyzed, and whether or not the image is projected by the image projection units 130 and 140 is controlled based on the analysis result. Good.

  In each of the above embodiments, an image that allows the user to stereoscopically view in three dimensions may be projected onto the image projection plane 200. Examples of images that can be stereoscopically viewed by the user include images that can be separated into a left-eye image and a right-eye image using dedicated image separation glasses such as a color filter method, a polarizing filter method, and a liquid crystal shutter method. Can be mentioned. The stereoscopic vision in this case is a mixture of parallel vision and cross vision in autostereoscopic vision.

  FIG. 9 is an explanatory diagram showing a state in which a stereoscopic image that can be separated into a left-eye image and a right-eye image is projected onto the same image projection plane 200 using the color filter type dedicated glasses 300. is there. A red color filter 300L is attached to the light passage portion for the left eye of the dedicated glasses 300, and a blue color filter 300R is attached to the light passage portion for the right eye. As a material for this color filter, red and blue films can be used in addition to glass materials.

  In the mobile phone 100 of FIG. 9, one image projection unit 130 projects an image for the left eye (blue image), and the other image projection unit 140 projects an image for the right eye (red image). Each image component included in the image for the left eye (blue image) and the image for the right eye (red image) is shifted by a predetermined distance in a predetermined direction. Due to this image shift, each image component can be seen close or far away.

It is explanatory drawing of. In FIG. 10, left-eye images (blue images) 311 to 313 are indicated by solid lines, and right-eye images (red images) 321 to 323 are indicated by broken lines. Here, the circular image components 312 and 322 in the center in the figure appear in the middle position, the elliptical image components 311 and 321 on the left side appear closer, and the rhomboid image component 313 on the right side. 323 appears far away.

  FIG. 11 is an explanatory diagram of a mechanism of stereoscopic viewing of the image of FIG. The left eye seen through the red optical filter 300L of the dedicated glasses 300 can only see the images for the left eye (blue images) 311 to 313. On the other hand, the right eye seen through the blue optical filter 300R of the dedicated glasses 300 can only see the right eye images (red images) 321-323. As a result, as shown in FIG. 11, the elliptical image component projected on the left side on the image projection plane 200 forms an image at a position closer to the front side than the image projection plane 200, and is displayed on the image projection plane 200. The rhomboid image component projected on the right side of the image is formed at a position farther away from the image projection plane 200. In addition, the circular image component projected on the central portion on the image projection plane 200 forms an image on the image projection plane 200. As described above, the oval, circular, and rhombus image components appear at different depths.

  In the example of FIG. 9 described above, the left-eye image (blue image) and the right-eye image (red image) are projected by different image projecting units 130 and 140, respectively. ) And the image for the right eye (red image) may be projected by one image projection unit.

FIG. 12 is an explanatory diagram illustrating a state in which a stereoscopic image that can be separated into a left-eye image and a right-eye image is projected onto the same image projection plane 220 using the polarizing filter type dedicated glasses 400. is there. A polarizing filter 400L having a polarization plane in the hatching direction in the drawing is attached to the light passage portion for the left eye of the dedicated glasses 400, and a polarization filter having a polarization plane in the hatching direction in the drawing is attached to the light passage portion for the right eye. A filter 400R is attached. The polarization planes of the two polarizing filters 400L and 400R intersect at a predetermined angle. The angle of this intersection is preferably 90 degrees from the viewpoint of separability between the left-eye image and the right-eye image.
One image projection unit 130 projects a left-eye image. A polarizing filter 137 having the same polarization plane inclination as that of the polarizing filter 400L for the left eye of the dedicated glasses 400 is attached to the light emitting unit of the image projecting unit 130. The other image projection unit 140 projects the right-eye image. A polarizing filter 147 having the same polarization plane inclination as that of the polarizing filter 400R for the right eye of the dedicated glasses 400 is attached to the light emitting unit of the image projecting unit 140.
Further, on the image projection surface 220, a dedicated screen (silver screen) that reflects the light of the image projected by the image projection units 130 and 140 while holding the polarization surface is supported by a support member (not shown) or the like. To do.
The image projection units 130 and 140 configured as described above project the left-eye image and the right-eye image on the image projection surface 220 of the dedicated screen in an overlapping manner. When the user views the projection image through the dedicated glasses 400 having the polarizing filters 400L and 400R, only the left eye image can be viewed with the user's left eye, and only the right eye image can be viewed with the user's right eye. . Thus, by separately viewing the left-eye image and the right-eye image for stereoscopic viewing, the user can enjoy a three-dimensional stereoscopic image.

  In addition to the color filter type dedicated glasses 300 and the polarization filter type dedicated glasses 400, liquid crystal filter type dedicated glasses may be used to separate the left eye image and the right eye image. A liquid crystal panel capable of shutter-controlling light passage independently of each other is attached to the light passage portion for the right eye and the light passage portion for the left eye of the dedicated glasses. Each liquid crystal panel is controlled to alternately pass light, and the image projection unit is controlled to alternately switch the left-eye image and the right-eye image projected onto the image projection surface in synchronization with the control of the liquid crystal panel. . For example, a right-eye image is projected when the right-eye liquid crystal panel of the dedicated glasses is opened, and a left-eye image is projected when the left-eye liquid crystal panel is opened. By turning on and off the shutter function of each LCD panel of this special glasses and switching the projected image at high speed, the left eye of the user only sees the image for the left eye, and the right eye of the user has the image for the right eye. Can only see. Thus, by separately viewing the left-eye image and the right-eye image for stereoscopic viewing, the user can enjoy a three-dimensional stereoscopic image. Note that the synchronization control between the ON / OFF of the shutter function of each LCD panel of the dedicated glasses and the switching of the projected image is performed by sending a control signal by communication via a communication cable connecting the dedicated glasses and the mobile phone, infrared, short-range wireless, etc. It can be executed by transmitting and receiving.

  In addition, an image that can be viewed stereoscopically by parallel viewing or cross-viewing in autostereoscopic viewing that does not require the use of the dedicated glasses may be projected.
