Yes.
The display unit 2 includes a camera unit 200, a projector module 6 (projector unit), a second operation member 205, a speaker 206, a main liquid crystal display 204, and a sub liquid crystal display 4.
The CPU 101 sends a control signal to each part of the projector-equipped mobile phone 10 by performing a predetermined calculation using a signal input from each part constituting the projector-equipped mobile phone 10 based on the control program. , Control phone operation, camera operation, projector operation. The control program is stored in a nonvolatile memory (not shown) in the CPU 101.
The memory 102 is used as a work area for the CPU 101. The attitude sensor 103 detects the attitude of the projector-equipped mobile phone 10 and sends a detection signal to the CPU 101. As a result, the CPU 101 acquires top and bottom information (including identification of vertical position shooting and horizontal position shooting) at the time of shooting, and is placed in a vertical position as shown in FIG. It is determined whether the leg parts 11 and 21 and the folding hinge part 3 are placed in the lateral position.
The short-range communication unit 104 is configured by, for example, an infrared communication circuit, and transmits / receives data to / from an external device according to a command from the CPU 101. The TV tuner 106 receives a television broadcast according to a command from the CPU 101. The CPU 101 displays the received image on the main liquid crystal display 204 and reproduces the received sound with the speaker 206. The memory card 105 is configured by a nonvolatile memory, and can store and read data such as image data output from the camera unit 200 and video / audio data output from the TV tuner 106, for example, according to instructions from the CPU 101.
The microphone 107 converts the collected sound into an electrical signal and sends it to the CPU 101. The audio signal is recorded in the memory card 105 during recording, and is sent to the communication control unit 110 during a call. The external interface 108 transmits / receives data to / from an external device via a cable or cradle (not shown) according to a command from the CPU 101.

The antenna 7 is a transmission / reception antenna of the communication control unit 110.
The power source 109 is composed of, for example, a detachable battery pack and a DC / DC conversion circuit, and supplies necessary power to each unit in the projector-equipped mobile phone 10. The opening / closing angle SW114 detects the turning angle of the folding hinge unit 3, and when it detects that the relative angle θ between the operation unit 1 and the display unit 2 has been set to 80 degrees (projection posture), an on signal (H level) is output. Sends to the CPU 101, and sends an off signal (L level) at other angles.

The camera unit 200 includes a photographic lens 5, an image sensor 201, a lens driving unit 202, and a camera control CPU 203. As the image sensor 201, a CCD, a CMOS image sensor, or the like is used. The camera control CPU 203 drives and controls the image sensor 201 and the lens driving unit 202 according to instructions from the CPU 101. When receiving a zoom control signal from the camera control CPU 203, the lens driving unit 202 drives a zoom lens (not shown) constituting the photographing lens 5 to the tele side or the wide side according to the control signal. The photographing lens 5 forms a subject image on the imaging surface of the image sensor 201. The camera control CPU 203 causes the image sensor 201 to start imaging, reads the accumulated charge signal from the image sensor 201 after completion of imaging, performs predetermined signal processing, and sends it to the CPU 101 as image data. Note that when image data captured by the camera unit 200 is transmitted, the image data is transmitted from the CPU 101 to the communication control unit 110. When projecting a captured image, image data is sent from the camera control CPU 203 to the projector module 6 via the CPU 101. The CPU 101 performs trapezoidal distortion correction processing on the image data projected by the projector module 6.
The projector module 6 includes a projection lens 61, a liquid crystal panel 62, an LED light source 63, an LED drive unit 64, a liquid crystal drive unit 65, and a lens drive unit 66. The LED drive unit 64 supplies current to the LED light source 63 in accordance with the LED drive signal output from the CPU 101. The LED light source 63 illuminates the liquid crystal panel 62 with brightness according to the supply current.
The liquid crystal drive unit 65 generates a liquid crystal panel drive signal according to the image data, and drives the liquid crystal panel 62 with the generated drive signal. Specifically, a voltage corresponding to the image signal is applied to the liquid crystal layer for each pixel. In the liquid crystal layer to which a voltage is applied, the arrangement of liquid crystal molecules changes, and the light transmittance of the liquid crystal layer changes. Thus, the liquid crystal panel 62 generates an optical image by modulating the light from the LED light source 63 in accordance with the image signal.
The lens driving unit 66 drives the projection lens 61 to move back and forth in a direction orthogonal to the optical axis based on a control signal output from the CPU 101. The projection lens 61 projects a light image emitted from the liquid crystal panel 62 toward a screen or the like.
A projection image by the projector module 6 will be described in detail. The projector-equipped mobile phone 10 is set to a projection posture in which the relative angle between the operation unit 1 and the display unit 2 is 80 degrees, and automatically starts projection when a predetermined time elapses. FIG. 3 is a diagram for explaining an image Iv projected on the screen S from the projector-equipped mobile phone 10 placed on the plane P in the vertical position. FIG. 3A is a view of the screen S as viewed from the front, and FIG. 3B is a view of the screen S viewed from the right side. In FIG. 3A, the center point C of the projected light beam of the projection image Iv is offset upward from the opening center O of the projector module 6. That is, as shown in FIG. 3B, the lower end of the projected light beam is made parallel or upward with respect to the plane P by adjusting the center line Fc of the projected light beam to the projection angle of the angle α with respect to the horizontal line. . The rotation position of the projector module 6 is set to 0 degrees. A point C in the figure represents the center of the projected light beam (the center of the projection image Iv), and a line connecting the opening center O and the point C corresponds to the light beam center line Fc.
Although the offset of the projection image is obtained by the projection angle α described above, the projection image as it is is trapezoidal. Therefore, the projection lens 61 is shifted by the lens driving unit 66 described above to obtain a tilt effect, and keystone correction (trapezoidal distortion correction) is performed on display data to be projected according to the tilt effect, whereby the projection image Iv is squared. to correct. As the lens shift amount and the keystone correction amount, initial correction values for correcting the projection image Iv into a square shape in the state of the projection attitude of 80 degrees are stored in the CPU 101 in advance.
FIG. 4 is a flowchart for explaining the flow of projector control processing performed by the CPU 101. The process shown in FIG. 4 is repeated while the power switch of the projector-equipped mobile phone 10 is turned on. In step S11 of FIG. 4, the CPU 101 determines whether the opening / closing angle switch 114 is on. When an ON signal is input from the opening / closing angle switch 114 (that is, when the relative angle between the operation unit 1 and the display unit 2 is set to a projection posture of 80 degrees), the CPU 101 makes a positive determination in step S11 and proceeds to step S12. If the ON signal is not input from the opening / closing angle switch 114 (that is, the projection posture is not set), a negative determination is made in step S11 and the determination process is repeated.
In step S12, the CPU 101 determines whether or not the ON signal from the opening / closing angle switch 114 is continued for 2 seconds or more. The CPU 101 makes an affirmative decision in step S12 when the ON signal is continued for 2 seconds or more, and proceeds to step S13. If the duration time is less than 2 seconds, the CPU 101 returns to step S11. Thereby, even if an ON signal is temporarily output from the opening / closing angle switch 114 in the process of opening the cellular phone 10 with a projector from the folded state or in the process of folding from the opened state, the process does not proceed to step S13. become.
In step S13, the CPU 101 turns on the power of the projector module 6 and proceeds to step S14. Specifically, a command is sent to the power source 109 so as to start power supply to the projector module 6. In step S14, the CPU 101 performs initial setting of the projector module 6 and proceeds to step S15. The initial setting includes initializing the liquid crystal driving unit 65, causing the lens driving unit 66 to perform a lens shift corresponding to the initial correction value, and maintaining the LED light source 63 off.
In step S15, the CPU 101 causes the projector module 6 to start projection and proceeds to step S16. Specifically, after a command is sent to the liquid crystal driving unit 65 so that the same content as that displayed on the main liquid crystal display 204 is formed on the liquid crystal panel 62, the display on the main liquid crystal display 204 is turned off. Then, a command is sent to the LED drive unit 64 to turn on the LED light source 63. Thereby, the initial projection content (initial screen) by the projector module 6 is the same as the content displayed on the main liquid crystal display 204. The content projected by the projector module 6 after the initial screen can be appropriately changed to an image taken by the camera unit 200, a broadcast screen received by the TV tuner 106, information received by the communication control unit 110, and the like. These selection processes are omitted in the flowchart of FIG.
In step S16, the CPU 101 determines whether or not the opening / closing angle switch 114 is off. When the off signal is input from the opening / closing angle switch 114 (that is, when the relative angle between the operation unit 1 and the display unit 2 is not in the projection posture of 80 degrees), the CPU 101 makes an affirmative determination in step S16 and proceeds to step S17. If the OFF signal is not input from the open / close angle switch 114 (that is, in the projection posture), a negative determination is made in step S16, and the process returns to step S15. Thereby, the state of the opening / closing angle switch 114 is always monitored during projection by the projector module 6.
In step S17, the CPU 101 determines whether or not the OFF signal from the open / close angle switch 114 has been continued for 0.5 seconds or more. The CPU 101 makes an affirmative determination in step S17 when the off signal is continued for 0.5 seconds or more and proceeds to step S18, and returns to step S15 when the duration is less than 0.5. As a result, even if an OFF signal is temporarily output from the open / close angle switch 114 by accidentally touching the projector-equipped mobile phone 10 during projection, the process does not proceed to step S18.
In step S18, the CPU 101 causes the projector module 6 to end projection and returns to step S11. Specifically, a command is sent to the LED drive unit 64 to turn off the LED light source 63, and the content (initial screen) displayed on the main liquid crystal display 204 before the projection by the projector module 6 is started again. It is displayed on the main liquid crystal display 204.
According to the first embodiment described above, the following operational effects can be obtained.
(1) The projector-equipped mobile phone 10 has passed a predetermined time (2 seconds in the above example) in a state in which the relative angle between the operation unit 1 and the display unit 2 is set to a projection posture of 80 degrees (Yes in step S11). When this is done (Yes in step S12), the projector module 6 automatically projects information. Thereby, it is only necessary to change the aspect to the projection posture, and the operation before the projection can be simplified, so that the usability is improved. In addition, since the projection is performed when the projection posture continues for 2 seconds, the relative angle is temporarily 80 degrees in the process in which the mobile phone with projector 10 is opened from the folded state to the talking posture or in the process of folding from the talking posture. Even if this happens, unnecessary projection is prevented.
(2) The shape of the projected image Iv is corrected to a square shape by combining the tilt effect by lens shift and the keystone correction using image processing so that the image Iv projected on the screen S does not become trapezoidal. The lens shift amount and the keystone correction amount necessary for obtaining a square projection image Iv in the projection posture are stored in the CPU 101 as initial correction values in advance, and the correction using the initial correction value is automatically performed before starting projection. (Step S14). Therefore, it is not necessary to perform a correction operation while confirming the projected image after the start of projection, and the operation after the start of projection can be simplified, so that the usability as a projector is improved.
(3) The projector-equipped mobile phone 10 automatically terminates the projection of information by the projector module 6 (step S18) when 0.5 seconds or longer has passed in a state where the projector is not in the projection position (Yes in step S17). did. Since the end requirement is 0.5 second, it is possible to prevent the projection from being terminated unintentionally when the mobile phone 10 with a projector is inadvertently touched during the projection.
In step S12 of the flowchart of FIG. 4, it may be determined that the projector-equipped mobile phone 10 is stably placed on a table or the like. That is, it is determined whether both the projector-equipped mobile phone 10 is in the projection posture and the projector-equipped mobile phone 10 is stably placed. In this case, when the ON signal from the opening / closing angle switch 114 continues for 2 seconds or more and the change of the detection signal by the attitude sensor 103 continues for 2 seconds or more and is equal to or less than the predetermined value, the process proceeds to step S13. When the ON signal from 114 is less than 2 seconds, or when the change of the detection signal by the attitude sensor 103 exceeds a predetermined value, the process returns to step S11. By detecting both the projection posture and the mounting state, it is possible to reliably determine the situation used as a projector and proceed to the projection process.
In step S12, it may be determined only that the projector-equipped mobile phone 10 is stably placed. In this case, when the change of the detection signal by the attitude sensor 103 continues for 2 seconds or more and is not more than the predetermined value, the process proceeds to step S13, and when the change of the detection signal by the attitude sensor 103 exceeds the predetermined value, the process proceeds to step S11. Try to go back. Even when only the state where the projector is stably placed is detected, it is possible to reliably determine the situation in which the projector is used and proceed to the projection process. When it is determined that the projector-equipped mobile phone 10 is stably placed and the process proceeds to the projection process, the projection is terminated when stable placement is not determined. In this case, if the state in which the change in the detection signal by the posture sensor 103 exceeds the predetermined value continues for 0.5 seconds in step S17, the process proceeds to step S18 and the projection is terminated.
The state of whether or not the projector-equipped mobile phone 10 is stably placed may be detected using image data obtained by the camera unit 200 instead of using the detection signal from the attitude sensor 103. In this case, a subject image is captured by the camera unit 200 every predetermined time. The CPU 101 detects the placement state of the projector-equipped mobile phone 10 by comparing the image data sent from the camera unit 200 with the latest image data at predetermined time intervals. If the difference (time change) from the most recent image data is greater than a predetermined value, it is determined that the projector-equipped mobile phone 10 is not placed. If the time difference is less than the predetermined value, the projector-equipped mobile phone 10 is stable. Is determined to be placed.
5A and 5B are perspective views of the projector-equipped mobile phone 50 according to the second embodiment of the present invention, in which FIG. 5A is a diagram showing a call posture, and FIG. 5B is a diagram showing a projection posture. 5 (a) and 5 (b), a cylindrical housing 52 is supported on the mobile phone body 51 by a rotatable support part 53, and the housing 52 is rotatable about the support part 53 (mode). Can be changed). The support portion 53 has a click mechanism (not shown) having a relative angle γ between the mobile phone 51 and the housing 52 of, for example, a position of 0 degrees (FIG. 5A) and a position of 150 degrees (FIG. 5B). Is provided. 0 degrees corresponds to the telephone conversation posture, and 150 degrees corresponds to the projection posture of the projector module 6.
The housing 52 accommodates a projector module similar to that of the first embodiment mobile phone (not shown), and is configured to output a projection light beam from the opposite side of the support portion 53 of the housing 52. The housing 52 is further provided with a switch (not shown) for detecting the rotation angle of the housing 52. The relative angle γ between the mobile phone body 51 and the housing 52 is set to 150 degrees (projection posture). When detected, an ON signal (H level) is output, and an OFF signal (L level) is output at other angles.
The CPU of the mobile phone main body 51 automatically causes the projector module to project information when a predetermined time (for example, 2 seconds) elapses in a state where the projection posture is a relative angle γ = 150 degrees. As a result, as in the first embodiment, it is possible to improve usability by simplifying the operations up to the projection, and to prevent unnecessary projection when the relative angle γ is temporarily 150 degrees.
FIG. 6 is a diagram illustrating a projector-equipped mobile phone 10a according to the third embodiment of the present invention. The arrangement position and projection direction of the projector module 6 are different from those of the projector-equipped mobile phone 10 according to the first embodiment.
The projector-equipped mobile phone 10a is set to a projection posture in which the relative angle between the operation unit 1 and the display unit 2a is set to 80 degrees, and automatically starts projection when a predetermined time elapses. In FIG. 6, the opening center O of the projector module 6 is disposed at a position away from the plane P, and the center line Fc of the projected light beam is configured to proceed in parallel with the plane P in the projection posture. A point C in the figure represents the center of the projected light beam, and a line connecting the aperture center O and the point C corresponds to the center line Fc of the light beam.
In the configuration shown in FIG. 6, in addition to the improvement in usability by simplifying the operation up to the projection, the optical path length between the upper end and the lower end of the projected light beam can be made equal, so that the keystone correction can be made unnecessary. As a result, an inexpensive projector-equipped mobile phone 10a can be obtained with a simple configuration.
In the above description, 2 seconds in the determination process in step S12 and 0.5 seconds in the determination process in step S17 may be appropriately selected without being limited to the above example. If it is desired to improve responsiveness, the determination time may be set to 0 seconds.
The mobile phone with a projector may be any of the folding type described above, a type obtained by adding a rotation mechanism of the display unit to the folding type, and a type not folding described above, and includes a movable mechanism that changes the mode of the device. Just do it. Further, the angle used for determining the projection posture is not limited to 80 degrees and may be set as appropriate.
In the above description, the example in which the projector module 6 is mounted on the projector-equipped mobile phone 10 has been described. However, the projector module 6 may be mounted on an electronic device such as a notebook computer, a PDA, an electronic camera, or a playback device instead of the projector-equipped mobile phone 10.
