Projector module 6 comprises projecting lens 61, liquid crystal panel 62, led light source 63, LED drive division 64, liquid crystal drive portion 65, lens drive division 66.LED drive division 64 provides electric current according to the LED drive signal of CPU101 output to led light source 63.Led light source 63 to be shining R (red), G (green), B (indigo plant) primaries respectively with the output of supplying electric current correspondence, and liquid crystal panel 62 is thrown light on.Light by each color synthetic is from led light source 63 irradiation white lights.In addition, the light intensity of each color of RGB can be by regulating respectively from the current strength of LED drive division 64.
Liquid crystal drive portion 65 is according to view data Generation Liquid crystal panel drive signal, and the drive liquid crystal panel 62 by generating, thus on liquid crystal panel 62 display image.Particularly, apply voltage with the picture signal correspondence according to each pixel to liquid crystal layer.The arrangement of liquid crystal molecule that has applied the liquid crystal layer of voltage changes, and the light transmittance of this liquid crystal layer changes.Modified-image by this light transmittance is shown.In addition, liquid crystal panel 62 has chromatic filter, and each pixel is of the same colour arbitrarily corresponding to RGB's.So, show the coloured image that each colored pixels of RGB is made up in the liquid crystal panel 62.
The image that the image that shows on the liquid crystal panel 62 can be preserved from storage card 104, from the image of external equipment input, following various images such as image, select by camera model 7 shootings.Also can be with host liquid crystal display 4, secondary LCD 5 in the identical image of image that shows, or dynamic image.And, also can select mail and demonstration.
As mentioned above, the image of selecting is shown to liquid crystal panel 62 after, the white light that has synthesized from each color of light of RGB of led light source 63 irradiations is passed through, thus the light image of the image that shows on the Generation Liquid crystal panel 62.Lens drive division 66 is according to the control signal of CPU 101 output, makes projecting lens 61 driving of advancing and retreat on optical axis direction.By changing the focal position of projecting lens 61, carry out the adjusting of the focus state of following projected image.Projecting lens 61 will be from optical projection that liquid crystal panel 62 penetrates to perspective planes such as screens.So, utilize the white light synthesized each coloured light of RGB with the image projection selected to the perspective plane, and the projected image of generation image.
Camera model 7 comprises photographic lens 71, imageing sensor 72, lens drive division 73, camera control cpu 74.Imageing sensor 72 uses CCD, CMOS capturing element etc.Camera control cpu 74 is according to the order of CPU 101, drive controlling imageing sensor 72 and lens drive division 73.Lens drive division 73 makes the focal adjustments lens (not shown) that constitute photographic lens 71 drive along the optical axis direction fore-and-aft direction according to the control signal from camera control cpu 74, thereby changes the concentrated position of photographic lens 71.So, the be taken focal adjustments of volume image.
Photographic lens 71 volume image that will be taken is imaged onto on the shooting face of imageing sensor 72.Camera control cpu 74 makes imageing sensor 72 begin to take, and reads from imageing sensor 72 in shooting end back and accumulates charge signal, on the basis of carrying out the prearranged signal processing, sends to CPU 101 as view data.In addition, when sending, send view data to communication control unit 108 from CPU 101 by camera model 7 shot image data.And, during the projection photographic images, send view data via CPU 101 to projector module 6 from camera control cpu 74.So, in camera model 7, obtain the photographic images of the body that is taken.
Fig. 3 is the sectional view of projector module 6.(a) be the sectional view of expression projector module 6 in the end view of mobile phone 10, (b) be its enlarged drawing.The lens drive division 73 of Fig. 2 has lens support sector 731 and drive motors 732.Lens support sector 731 be configured in projecting lens 61 about, projection support lens 61.Drive motors 732 makes the position of lens support sector 731 move to the left and right directions of figure by its drive actions, thus the interval between adjustable liquid crystal panel 62 and led light source and the projecting lens 61.So, the focus state of scalable projected image.In addition, about LED drive division 64 and the liquid crystal drive portion 65 of Fig. 2, in Fig. 3, omit its diagram.
Then explanation movement content during projected image in projector-equipped mobile telephone 10.Projector-equipped mobile telephone 10 is carried out following action repeatedly when projector, image projection: be used for adjusting the action (hereinafter referred to as calibration actions) of video picture degree on the perspective plane of the projected image that is generated by projector module 6.This calibration actions is categorized as following action: the adjusting of (1) focus state, (2) brightness regulation, (3) white balance adjusting, (4) keystone correction.Above-mentioned each action of next coming in order explanation.
(1) adjusting of focus state
When the focus state of projected image was inappropriate, promptly during the incorrect coupling of the focus of distance till the perspective plane and projected image, focus produced deviation, can mirror fuzzy projected image in projector module 6.In order to mirror the projected image that focus is coincide, need be adjusted to suitable focus state.The adjusting of the focus state of this projected image is undertaken by following action according to the photographic images of the projected image of being taken and being obtained by camera model 7.
Projector-equipped mobile telephone 10 utilizes camera model 7 to take these projected images during by projector module 6 projected images.The photographic images of the projected image of obtaining in camera model 7 outputs to CPU 101.CPU 101 judges by detecting the fog-level by the photographic images of camera model 7 outputs whether the focus state of projected image is suitable.When photographic images is fuzzy, judge that focus state is inappropriate, utilize lens drive division 66 to drive projecting lens 61.So, till photographic images is no longer fuzzy, drive projecting lens 66, thereby regulate the focus state of projected image, become suitable focus state.
The same method of Contrast Detection mode that the adjusting of above-mentioned focus state can extensively be adopted when regulating the focal position with digital camera is carried out.That is, make the focal position of projecting lens 61 carry out various variations and obtain photographic images, each photographic images is calculated making a gesture of measuring.And, relatively each photographic images to making a gesture of measuring, the focal position that makes projecting lens 61 is corresponding to the position of obtaining when making a gesture of measuring maximum photographic images.So, can suitably regulate the focus state of projected image.In addition, need carry out focal adjustments, the white balance adjusting of photographic images this moment in camera model 7, this is described after a while.
But in the adjustment process of projected image focus state, when this projected image self changed, changing making a gesture of measuring also of photographic images can't obtain suitable adjusting result.Particularly when the projection dynamic image, often change, therefore can't regulate the focus state of projected image owing to projected image.Therefore in projector-equipped mobile telephone 10, to the selecteed doubling of the image is used to calculate to the predetermined picture of making a gesture of measuring (calculate use image hereinafter referred to as contrast) as projected image, afterwards with it by projector module 6 projections and by camera model 7 shooting projected images.So, even original projection objects image changes, the part that overlapping contrast is calculated with image does not change yet.Therefore, by contrast being calculated with image calculation making a gesture of measuring, and according to this to making a gesture of measuring the focus state of regulating projected image, even when the projection dynamic image, also can suitably regulate the focus state of projected image.
Fig. 4 is that expression calculates contrast with the figure of the doubling of the image to the form of projection objects image.(a) the original projection objects image of expression, (b) expression calculates contrast with the image of the doubling of the image to the projection objects image of (a).In the image of (b), add filename and date and time information in the lower end, the contrast shown in the overlapping label 21 is calculated and is used image.This contrast is calculated with image has reservation shape with a plurality of connections of ordinate, calculates making a gesture of measuring being easy to.Thisly contain the image that the contrast that formed by the reservation shape pattern calculates with image 21 and project on the perspective plane by projector module 6, this projected image is by camera model 7 shootings.Utilize the photographic images of obtaining like this, calculating calculates making a gesture of measuring with image 21 according to contrast, carries out the adjusting of the focus state of projected image.In addition, the contrast calculating shown in here is examples with the shape pattern of image 21, so long as can calculate what make a gesture of measuring, can be the pattern of arbitrary shape.
And, above-mentioned in the calculating of making a gesture of measuring, from the shooting signal (accumulate charge signal) of imageing sensor 72 with pixel unit output of camera model 7, only use from calculating the shooting signal of the pixel output in the zone of using image 21 correspondences with contrast.
Above-mentioned contrast is calculated needn't always carry out the short period that can only be scheduled to the overlapping of image.So, can make subtle calculating of the people who observes projected image use the doubling of the image to contrast.Fig. 5 is the sequential chart that is used to illustrate this form.The image that shows in the liquid crystal panel 62 upgraded once with the sequential shown in the label 31 in per 1/30 second.That is, show the image of 30 frames a second.
Contrast is calculated and is carried out with certain frame period according to the sequential shown in the label 32 with the overlapping of image.Under this sequential, contain the image that contrast calculates with image and be projected, under other sequential, do not contain contrast calculating and be projected with the image of image.At this moment, carry out obtaining of 7 pairs of photographic images of camera model by sequential shown in the label 33.That is, to calculate the sequential that the image with image is projected synchronous with containing contrast, takes projected image in camera model 7.Calculate partial shape pattern according to the contrast in the photographic images of taking, with the adjusting of the focus state of the calculating of the sequential amount of comparing shown in the label 34 and projected image with image.
Further, the adjusting of the focus state of projected image is carried out repeatedly with the fixed cycle as mentioned above.Perhaps, also can when the input operation of projector-equipped mobile telephone 10 being carried out to operation keys, carry out repeatedly.When the input operation carried out operation keys, position, the direction of projector-equipped mobile telephone 10 change, and can produce the situation that projected image waves.Therefore, when carrying out the input operation of operation keys, regulate the focus state of projected image,, thereby can present the projected image that is easy to watch even when projected image waves, also can proofread and correct to it.
Perhaps, also can set the regulating frequency of focus state.For example, can set three kinds of regulating frequencies, when setting the highest regulating frequency, when projector, image projection, carry out the adjusting of focus state as mentioned above repeatedly.On the other hand, when being set at Neutral colour adjusting frequency, only at first once at projector, image projection the time, carry out the adjusting of focus state, when being set at minimum regulating frequency, do not carry out the adjusting of the focus state of projected image.So, when the adjusting of the focus state that does not need projected image, can suppress power consumption.In addition, the setting of regulating frequency also can wait by the input operation of operation keys and carry out.
In the above description, calculate by overlapping contrast and to use image, though when the projection dynamic image the also focus state of scalable projected image.If but the image of projection is a rest image, then calculate making a gesture of measuring according to this rest image, can suitably regulate the focus state of projected image.Therefore, also degree of comparing does not calculate and uses the overlapping of image, only regulates the focus state of projected image when the projection rest image.Further, when the projection dynamic image, overlapping contrast is calculated and is used image, when the projection rest image, not overlapping contrast is calculated and is used image, and any one that calculate with image or rest image according to contrast calculates making a gesture of measuring, and regulates the focus state of projected image.
(2) brightness regulation
Brightness regulation then is described.When can't carry out projection with appropriate brightness in projector module 6 time, projected image either overt or covert being difficult for watches, and therefore needs suitably to regulate the brightness of projected image.It is the same that the brightness regulation of this projected image and above-mentioned focus state are regulated, and carries out according to the photographic images by camera model 7 shootings and the projected image obtained.
Projector-equipped mobile telephone 10 detects the brightness by the photographic images of camera model 7 outputs in CPU 101, thereby whether the brightness of judging projected image is suitable.Cross bright or cross when dark when photographic images is whole, judge that the brightness of projected image is inappropriate, increase or reduce the supplying electric current that is provided to led light source 63 from LED drive division 64.According to supplying electric current amount from LED drive division 64, the luminous intensity variations of led light source 63, the brightness of projected image changes.So the brightness of projected image is conditioned suitably.
In addition, led light source 63 carries out PWM when lighting, can be by changing the brightness of its duty cycle adjustment projected image.That is, when led light source is the pulse type luminous light source, projected image is brightened, can make the projected image deepening by reducing pulse amplitude on the contrary by amplifying this pulse amplitude.Further, led light source 63 makes each coloured light multi-group light-emitting of RGB, can light the also brightness of scalable projected image of group number by changing it according to the control connection/when closing of lighting respectively of each group.By said method, can change the luminous quantity of led light source 63 and regulate the brightness of projected image.
When projector-equipped mobile telephone 10 is regulated projected image brightness according to photographic images as mentioned above, be used for the predetermined image (hereinafter referred to as brightness detection image) of sensed luminance to the doubling of the image that is selected as projection objects after, it is taken with camera model 7 by projector module 6 projections and with this projected image.So,, also can detect the part brightness of using image, suitably regulate the brightness of projected image according to overlapping brightness even original projection objects image changes.
Fig. 6 is that expression detects brightness with the aspect graph of the doubling of the image to the projection objects image.(a) the original projection objects image of expression, (b) expression detects brightness with the image of the doubling of the image to the projection objects of (a).In the image of (b), calculate with the image of image equally with the overlapping contrast of Fig. 4 (b), add filename and date and time information in the lower end, the brightness shown in the overlapping label 22 detects uses image.This brightness detection in order to be easy to detect brightness, has whole reservation shape pattern for colourless (white) with image 22.Contain the image that is detected with image 22 by the brightness of reservation shape pattern and project on the perspective plane by projector module 6, this projected image is taken by camera model 7.Utilize the photographic images of obtaining like this, detect according to brightness and detect brightness, carry out the brightness regulation of projected image with image 22.In addition, the shape pattern that the brightness shown in here detects with image 22 is an example, so long as what can detect brightness can be the arbitrary shape pattern.
In addition, during above-mentioned brightness detects,, only use from detecting shooting signal with the pixel output in the zone of image 22 correspondences with brightness from the shooting signal (accumulating charge signal) of imageing sensor 72 with pixel unit output of camera model 7.
Above-mentioned brightness detects with the overlapping and above-mentioned contrast calculating of image the same with image, the short period that can only be scheduled to.In this case, it is synchronous with the image and the projection sequential of image to contain the brightness detection, takes projected image in camera model 7.
And, to regulate equally with above-mentioned focus state, the brightness regulation of this projected image also can be carried out repeatedly according to the fixed cycle, perhaps, also can carry out repeatedly when the input operation of projector-equipped mobile telephone 10 being carried out to operation keys.When the input operation carried out operation keys, position, the direction of projector-equipped mobile telephone 10 change, and change with the distance on perspective plane, can produce the situation that projected image brightness changes.Therefore, when carrying out the input operation of operation keys, regulate the focus state of projected image, even when changing because of this input operation projected image brightness, also recoverable brightness and present the projected image that is easy to watch.
Perhaps, the same with the focus state adjusting, set from three kinds of brightness regulation frequencies by the input operation of operation keys.That is, when setting the highest regulating frequency, when projector, image projection, carry out brightness regulation repeatedly, when being set at Neutral colour adjusting frequency, only at first once at projector, image projection the time, carry out brightness regulation, when being set at minimum regulating frequency, do not carry out the brightness regulation of projected image.So, when not needing the brightness regulation of projected image, can suppress power consumption.
In the above description, make the luminous quantity variation of led light source 63 and the brightness of adjusting projected image.But, therefore preferably suppress luminous quantity owing to improve the increase that luminous quantity can cause electric power consumption, heat dissipation capacity as far as possible.So can preestablish predetermined reference value to the brightness of projected image, only when darker, reduce luminous quantity to regulate the brightness of projected image than this fiducial value.In this case, when brighter, by changing the brightness of the brightness regulation projected image of the projection objects image self of demonstration on the liquid crystal panel 62 than fiducial value.In the tone variations of this moment, can use methods such as LUT (Look Up Table) processing, γ treatment for correcting.In LUT handles, according to the corresponding relation of formization, each the color of pixel value of information in the image correcting data.In the γ treatment for correcting, according to the conversion curve that is called gamma curve, each the color of pixel value of information in the image correcting data.Also can use the brightness of method change projection objects image in addition.
(3) white balance adjusting
Then make balance adjustment clear.If in projector module 6, do not regulate the tone of projected image, then because of around luminous intensity distribution situation, the tone on perspective plane etc., can exist projected image to look the situation different with original tone.Therefore, identical in order to make projected image with original tone, need carry out white balance adjusting.The white balance adjusting of this projected image is regulated with above-mentioned focus state, brightness regulation is the same, carries out according to the photographic images of the projected image of being taken and being obtained by camera model 7.
Projector-equipped mobile telephone 10 judges by detect the tone by the photographic images of camera model 7 outputs in CPU 101 whether the white balance of projected image is suitable.Increase or reduce the supplying electric current that is provided to led light source 63 from LED drive division 64 according to each color of RGB.According to the supplying electric current amount from LED drive division 64, RGB luminous intensity of all kinds changes respectively in led light source 63, the tone variations of projected image.Regulate by this tone, can make the white balance of projected image be conditioned suitably.
In addition, the same during with above-mentioned brightness regulation, when led light source 63 carries out PWM when lighting, thereby can regulate the tone of projected image according to RGB change duty ratio of all kinds.That is, when led light source is during according to RGB pulse type luminous light source of all kinds, strengthen by amplifying the tone that pulse amplitude makes its illuminant colour, on the contrary can be by reducing the tone that pulse amplitude weakens illuminant colour.Further, when led light source 63 makes each coloured light multi-group light-emitting of RGB, make according to the color difference and to light number and change, thus the tone of scalable projected image.By said method, led light source 63 is changed according to each illuminant colour, and regulate the tone of projected image, thereby carry out the white balance adjusting of projected image.
When projector-equipped mobile telephone 10 is regulated the projected image white balance according to photographic images as mentioned above, be used to detect the predetermined image (hereinafter referred to as tone detection image) of tone to the doubling of the image that is selected as projection objects after, it is taken with camera model 7 by projector module 6 projections and with this projected image.So, even original projection objects image changes, also can detect the part tone of using image, the white balance of suitably regulating projected image according to overlapping tone.
Above-mentioned tone detects with image can be also used as the brightness detection image 22 shown in Fig. 6 (b).Tone detects with image (brightness detects and uses image) 22 has whole reservation shape pattern for colourless (white).Therefore, in the photographic images of obtaining by camera model 7, detect tone with image (brightness detects and uses image) 22, this tone is compared with original white according to the tone detection, thus the scalable white balance.In addition, so long as what can carry out white balance adjusting can be the pattern of arbitrary shape.The employed contrast calculating of the adjusting of the focus state of projected image also can be used as tone with the white portion in the image and detects with image, brightness detection image.
In addition, during above-mentioned tone detects,, only use the shooting signal of using the pixel in the zone of image 22 correspondences to export from detection with tone from the shooting signal (accumulating charge signal) of imageing sensor 72 with pixel unit output of camera model 7.
Above-mentioned tone detects with the overlapping and above-mentioned contrast calculating of image the same with image with image, brightness detection, the short period that can only be scheduled to.In this case, it is synchronous with the image and the projection sequential of image to contain the tone detection, takes projected image in camera model 7.
And, to regulate with above-mentioned focus state, brightness regulation is the same, this white balance adjusting also can be carried out the fixed cycle repeatedly, perhaps, also can carry out repeatedly when the input operation of projector-equipped mobile telephone 10 being carried out to operation keys.When the input operation carried out operation keys, position, the direction of projector-equipped mobile telephone 10 change, and can produce the situation of projected image change in location.At this moment, because the variation of projected image position, luminous intensity distribution situation on every side, the tone on perspective plane also change, and consequently, the tone of projected image changes.Therefore, when carrying out the input operation of operation keys, regulate the white balance of projected image, even when changing because of this input operation projected image brightness, also recoverable tone and present the projected image that is easy to watch.
Perhaps, regulate with focus state, brightness regulation is the same, from three kinds of white balance adjusting frequencies, set by the input operation of operation keys.That is, when setting the highest regulating frequency, when projector, image projection, carry out white balance adjusting repeatedly, when being set at Neutral colour adjusting frequency, only at first once at projector, image projection the time, carry out white balance adjusting, when being set at minimum regulating frequency, do not carry out the white balance adjusting of projected image.So, when not needing the white balance adjusting of projected image, can suppress power consumption.
In the above description, be the adjusting that example has illustrated white balance with the tone of regulating projected image, also applicable to being the situation that benchmark is regulated tone with the color beyond white.
(4) keystone correction
Keystone correction is described at last.Trapezoidal distortion is meant, the trapezoidal distortion of the projected image that produces because of the angle of the projecting direction of projector module 6 and projection surface.When projecting direction and perspective plane not over against the time, can produce this trapezoidal distortion.The correction of this trapezoidal distortion is the same with above-mentioned various adjustings, carries out according to the photographic images of the projected image of being taken and being obtained by camera model 7.
Projector-equipped mobile telephone 10 detects the shape by the photographic images of camera model 7 outputs in CPU 101, judge whether produced trapezoidal distortion in the projected image.When producing trapezoidal distortion, control liquid crystal drive portion 65 on the direction opposite with this trapezoidal distortion, makes the figure anamorphosis that shows on the liquid crystal panel 62, eliminates trapezoidal distortion.And proofread and correct trapezoidal distortion by this image of projection.
When projector-equipped mobile telephone 10 is proofreaied and correct trapezoidal distortion according to photographic images as mentioned above, be used for the predetermined pattern (determining to use figure) of the shape of definite projected image to the doubling of the image that is selected as projection objects after, it is taken with camera model 7 by projector module 6 projections and with this projected image hereinafter referred to as shape.So, no matter be the projection objects image of what content, all can determine to use the figure adjustment trapezoidal distortion according to overlapping shape.
Fig. 7 is that expression determines shape with the figure of graphics overlay to the form of projection objects image.(a) the original projection objects image of expression, (b) expression determines shape with the image of the doubling of the image to the projection objects image of (a).In the image of (b), overlapping around the projection objects image have the shape of thick frame to determine with figure 23.Contain this shape and determine to project to the perspective plane with the image of figure 23 by projector module 6, this projected image is taken by camera model 7.Utilize the photographic images of obtaining like this, determine to carry out the correction of trapezoidal distortion with the shape of figure 23 definite projected images according to shape.In addition, the shape shown in determines with figure 23 to be examples here, so long as what can determine the projected image shape can be figure arbitrarily.Perhaps also can use mark, literal etc. without figure.
Above-mentioned shape determines to use the overlapping and above-mentioned contrast calculating of figure the same with image with image, tone detection with image, brightness detection, the short period that can only be scheduled to.In this case, contain shape and determine to use the image and the projection sequential of image synchronous, in camera model 7, take projected image.
And the same with above-mentioned various adjustings, this keystone also can carry out the fixed cycle repeatedly, perhaps, also can carry out repeatedly when the input operation of projector-equipped mobile telephone 10 being carried out to operation keys.When the input operation carried out operation keys, position, the direction of projector-equipped mobile telephone 10 change, and the projecting direction of projected image and the angle on perspective plane change, consequently, and the situation that exists the shape of trapezoidal distortion to change.Therefore, when carrying out the input operation of operation keys, carry out the correction of trapezoidal distortion, even the time because of this input operation trapezoidal distortion change of shape, also recoverable trapezoidal distortion and present the projected image that is easy to watch.
Perhaps, the same with above-mentioned various adjustings, set from three kinds of keystone correction frequencies by the input operation of operation keys.Promptly, when setting the highest regulating frequency, when projector, image projection, carry out the correction of trapezoidal distortion repeatedly, when being set at Neutral colour adjusting frequency, only at first once at projector, image projection the time, carry out the correction of trapezoidal distortion, when being set at minimum regulating frequency, do not carry out the correction of the trapezoidal distortion of projected image.So, at the timing that does not need trapezoidal distortion, can suppress power consumption.
In the above description, taken shape overlapping and determined image, determined to determine the shape of projected image according to this shape, thereby carry out the correction of trapezoidal distortion with figure with figure.But, also can carry out the correction of trapezoidal distortion according to by opening and closing angular transducer 12 detected folding angle θ.At this moment, the projecting direction of the projected image of projector module 6 is fixed to display part 2.So, when the bottom surface portions with operating portion 1 is set to the first-class and projection of desk, can not proofread and correct trapezoidal distortion easily even do not take yet.
Fig. 8 is the figure of relation when being illustrated in setting operation portion 1 on the horizontal plane and projecting to vertical perspective plane, folding angle θ and trapezoidal distortion.(a) be the end view of the projection form of folding angle θ when spending, the front view of the form of the trapezoidal distortion when (b) being (a) less than 90.(c) be the end view of the projection form of θ=90 when spending, the front view of the form of the trapezoidal distortion when (d) being (b).
Shown in Fig. 8 (a) and (b), when spending less than 90, folding angle θ produces trapezoidal distortion.And, in contrast, when folding angle is spent greater than 90, trapezoidal distortion takes place.The degree of this trapezoidal distortion (distortion level) determines its variation ratio because of folding angle θ changes.Therefore, according to the value of folding angle θ, in order to eliminate trapezoidal distortion, the distortion level when the image that shows on the liquid crystal panel 62 being carried out distortion, recoverable trapezoidal distortion by preestablishing.In addition, shown in Fig. 8 (c), (d), when spending, θ=90, therefore need not to carry out keystone correction because trapezoidal distortion does not take place.
Perhaps also can: in projector-equipped mobile telephone 10, with the central shaft about display part 2 is rotating shaft, with this rotating shaft is the rotatable display part 2 in center, detect the anglec of rotation, and carry out the correction of trapezoidal distortion according to detected anglec of rotation φ with respect to predetermined reference position.In addition, in this case, the projecting direction of the projected image of projector module 6 is fixed to display part 2.
Fig. 9 is the figure of the relation of anglec of rotation φ when being illustrated in setting operation portion 1 on the horizontal plane and projecting to vertical perspective plane, display part 2 and trapezoidal distortion.(a) be the vertical view of the projection form of anglec of rotation φ when spending, the front view of the form of the trapezoidal distortion when (b) being (a) less than 90.(c) be the vertical view of the projection form of φ=90 when spending, the front view of the form of the trapezoidal distortion when (d) being (b).In addition, the reference position of anglec of rotation φ is the left and right sides central shaft of operating portion 1 in Fig. 9, and folding angle θ is 90 degree.Anglec of rotation φ is 90 when spending, the back side of display part 2 and perspective plane over against.
Shown in Fig. 9 (a) and (b), when spending less than 90, anglec of rotation φ produces trapezoidal distortion.And, in contrast, when anglec of rotation φ spends greater than 90, trapezoidal distortion takes place.The degree of this trapezoidal distortion (distortion level) determines its variation ratio because of anglec of rotation φ changes.Therefore, the same with folding angle θ, according to the value of anglec of rotation φ, in order to eliminate trapezoidal distortion, the distortion level when the image that shows on the liquid crystal panel 62 being carried out distortion, recoverable trapezoidal distortion by preestablishing.In addition, shown in Fig. 9 (c), (d), when spending, φ=90, therefore need not to carry out keystone correction because trapezoidal distortion does not take place.
Further, the correction of the above-mentioned trapezoidal distortion based on folding angle θ of use also capable of being combined, and based on the correction of the trapezoidal distortion of anglec of rotation φ.
As mentioned above, by adjusting, brightness regulation, the white balance adjusting of carrying out focus state, each actions such as correction that reach trapezoidal distortion, carry out calibration actions.In addition, need not all to carry out each action, can only carry out the action of selection.
Then the method for the focus of photographic images is regulated in explanation in camera model 7.In the focal adjustments of photographic images, use the method that is called the Contrast Detection mode.Particularly, make the focal position of photographic lens 71 carry out various variations and obtain photographic images, each photographic images is calculated making a gesture of measuring.And, in CPU 101 relatively each photographic images to making a gesture of measuring, for the focal position that makes photographic lens 71 corresponding to the position of obtaining when making a gesture of measuring maximum photographic images, to camera control cpu 74 output control signals.In order suitably to take the photographic images of projected image and to carry out calibration actions, need carry out the focal adjustments of this photographic images.
The focal adjustments of photographic images can be carried out simultaneously with the adjusting of the focus state of the projected image that carries out in projector module 6, also can carry out respectively.Use the control method that is called with the focus move mode when carrying out at the same time, when carrying out respectively, use the control method that is called the camera fixed form.Next coming in order illustrate the content of these control methods.
(with the focus move mode)
In this control method, make camera model 7 the shooting focal position, be the focal position of photographic lens 71, with the project focus spot position of projector module 6, change when to be projecting lens 61 with respect to the focal position of projected image keep identical position relation with respect to photographic images.Wherein, taking the focal position is that identical position relation is meant with the project focus spot position, to the distance of projector-equipped mobile telephone 10 two focal positions about equally.And, on different a plurality of project focus spots positions, generate projected image by projector module 6 respectively, the photographic images of these a plurality of projected images by camera model 7, is being kept respectively obtaining respectively on a plurality of shootings focal position of same position relation with this a plurality of project focus spots position.Photographic images to a plurality of projected images of obtaining calculates respectively making a gesture of measuring, and regulates and takes focal position and project focus spot position, makes it corresponding to the position when making a gesture of measuring maximum.So, carry out the adjusting of the focus state of the focal adjustments of photographic images and projected image simultaneously.Further, this moment is according to a plurality of photographic images of obtaining, except the adjusting of the focus state of projected image, also can carry out other calibration actions.
Figure 10 is that expression utilizes and above-mentionedly carries out the aspect graph that the focus state of the focal adjustments of photographic images and projected image is regulated simultaneously with the focus move mode.In (e), on the position of the about 50cm in distance perspective plane, be provided with projector-equipped mobile telephone 10 at Figure 10 (a).In addition, the distance of the best projection in the projector module 6 is about 50cm.
At first shown in (a), make the shooting focal position of camera model 7 and the project focus spot position of projector module 6 all be the aligned in position of 60cm in distance projector-equipped mobile telephone 10.Under this state, in camera model 7, take the projected image that generates by projector module 6, this photographic images is calculated making a gesture of measuring.Then shown in (b), make the shooting focal position of camera model 7 and the project focus spot position of projector module 6 all be the aligned in position of 55cm, the photographic images of this projected image is calculated making a gesture of measuring in distance projector-equipped mobile telephone 10.
Afterwards shown in (c) to (e), the project focus spot position that makes the shooting focal position of camera model 7 and projector module 6 is respectively in the aligned in position of distance projector-equipped mobile telephone 10 for 50cm, 45cm, 40cm, and the photographic images of the projected image under this position is calculated making a gesture of measuring.And the shooting focal position of camera model 7 and the project focus spot position of projector module 6 are regulated in the position during corresponding to acquisition maximum contrast amount.So, when carrying out the focal adjustments of photographic images, carry out the adjusting of the focus state of projected image.
When using the same focus move mode of above-mentioned explanation, the shooting focal position of camera model 7 and the project focus spot position of projector module 6 are remained on apart from the projector-equipped mobile telephone 10 basic positions that equate.Wherein, the project focus spot position is near more far from the perspective plane, produces the projected image of high-contrast more, and it is near more far from the perspective plane to take the focal position, more can high-contrast obtains the photographic images of projected image.Therefore,, can make the difference that calculates under focus state and the non-focusing state bigger, can correctly regulate simultaneously and take focal position and project focus spot position making a gesture of measuring by using with the focus move mode.Therefore, can in camera model 7, suitably take projected image.In addition, when needing more high accuracy, after the temporary transient alignment in shooting focal position that the method for stating is in the use tried to achieve and project focus spot position, change in the scope of the further focal position of refinement as the center and to take focal position and project focus spot position, and repeat same processing and get final product.
(camera fixed form)
In this control method, under the state of the fixing shooting focal position of camera model 7, only change the project focus spot position of projector module 6.And, on a plurality of different project focus spot positions, generate the photographic images of projected image, and on a shooting focal position of the photographic images of having fixed these a plurality of projected images, obtain.The photographic images of a plurality of projected images of obtaining is calculated respectively making a gesture of measuring,, regulate the project focus spot position of projector module 6 corresponding to the position when making a gesture of measuring maximum.
After having regulated the project focus spot position, further when the photographic images of above-mentioned a plurality of projected images of obtaining on a shooting focal position by camera model 7 satisfies predetermined condition, particularly, the maximum contrast amount that calculates when the photographic images by these a plurality of projected images is during less than predetermined threshold value, photographic images according to these a plurality of projected images, the maximum contrast amount that utilization calculates makes and takes the focal position and align on the position identical with the project focus spot position.Afterwards, on the shooting focal position after this adjusting, only change the project focus spot position once more,, carry out once more: the obtaining of the photographic images of a plurality of projected images of the generation of a plurality of projected images of projector module 6, camera model 7 with above-mentioned the same.Calculate making a gesture of measuring for each photographic images of obtaining,, regulate the project focus spot position corresponding to the position of this maximum contrast amount.By carrying out this processing repeatedly, carry out the adjusting of the focus state of the focal adjustments of photographic images and projected image respectively.At this moment, according to a plurality of photographic images of obtaining, except the focus state of regulating projected image, can carry out other calibration actions simultaneously.
Figure 11 is the aspect graph that focus state that expression utilizes the camera fixed form of above explanation to carry out the focal adjustments of photographic images and projected image is respectively regulated.The same with Figure 10 in Figure 11 (a) to (e), projector-equipped mobile telephone 10 is set on the position of the about 50cm in distance perspective plane, the best projection distance in the projector module 6 is about 50cm.
