Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 1 and Fig. 2, the preferred embodiment that the present invention prevents signal switching to cause picture to show abnormal display device 1 comprises the microprocessor (MicroControllerUnit that a scale controller (Scaler) 11, is electrically connected with this scale controller 11, MCU) 12, and the display 13 that is electrically connected with this scale controller 11.In this preferred embodiment, this display device 1 adopts version to be that the HDMI (High Definition Multimedia Interface) of " 1.4 " receives an image signal, such as 2D picture or 3D picture.
This scale controller 11 for receiving this image signal, and produces an image frame.
This microprocessor 12 should the current sequential data of image signal for obtaining a pair according to this image signal.Wherein this current sequential data comprises should a signal frequencies value, a resolution value of image signal, and one scan frequency values.
This image frame that this display 13 produces for showing this scale controller 11.
Below coordinating a prevention signal to switch causes picture to show abnormal display packing, and for above-mentioned scale controller 11, microprocessor 12, and the interaction between display 13 illustrates further.
First, after user starts this display device 1, this scale controller 11, and this microprocessor 12 just comes into operation.
As shown in step S21, this scale controller 11 receives this image signal, for this microprocessor 12 according to this image signal, obtains should this current sequential data of image signal.That is, this microprocessor 12 can resolve this image signal to obtain this current sequential data.Wherein carrying as above-mentioned, this current sequential data comprises this signal frequencies value, this resolution value, and the information such as this sweep frequency value.
As shown in step S22, the initial sequential data that this microprocessor 12 is given tacit consent to according to this current sequential data and one, judges whether this image signal is in steady state (SS).In this preferred embodiment, this initial sequential data preset can comprise signal frequencies value, the resolution value of corresponding 2D signal, and the information such as sweep frequency value, also can comprise signal frequencies value, the resolution value of corresponding 3D signal, and the information such as sweep frequency value.
In this preferred embodiment, when signal frequencies value, resolution value and sweep frequency value that this current sequential data comprises, when the signal frequencies value, the resolution value that comprise of sequential data initial with this is equal with sweep frequency value respectively, then this microprocessor 12 judges that this image signal is in steady state (SS).In other words, if the signal frequencies value that this current sequential data comprises, resolution value and sweep frequency value wherein at least one, when the signal frequencies value, resolution value and the sweep frequency value that comprise with this initial sequential data are unequal, then this microprocessor 12 judges that this image signal plays pendulum.Generally speaking, when this microprocessor 12 judges that this image signal plays pendulum, this scale controller 11 can not produce any image frame, and that is, this display 13 cannot show any image frame and view and admire for user.
For example, suppose that the resolution value of this current sequential data is for " 1280*720 ", and the resolution value of this initial sequential data is " 1920*1080 ", then this microprocessor 12 judges that this image signal plays pendulum, and this scale controller 11 can not produce the image frame for the display of this display 13.
As shown in step S23, if this image signal is in steady state (SS), then this microprocessor 12 judges whether this scale controller 11 has produced an image frame.
As shown in step S24, if this scale controller 11 has produced this image frame, then this microprocessor 12 has judged whether this current sequential data comprises a 3D form instruction data.
In this preferred embodiment, this 3D form instruction data is primarily of the 7th, the 6th in the 5th byte (PB4) of the content structure (HDMIVendorSpecificInfoFramePacketContents) of the vendor specific information frame grouping in HDMI (High Definition Multimedia Interface) framework, and the 5th formed.Further, above-mentioned three bit representation HDMI video forms (HDMI-Video-Format), when being " 010 " by a high position to the permutation and combination of low level for above-mentioned three, then this microprocessor 12 judges that this current sequential data comprises this 3D form instruction data.On the contrary, when above-mentioned three positions are not " 010 " by a high position to the permutation and combination of low level, then this microprocessor 12 judges that this current sequential data does not comprise this 3D form instruction data.
It is worth mentioning that, when this image signal is 3D signal, this microprocessor 12 also can according to the 7th, the 6th, the 5th in the 6th byte (PB5) of the content structure of the vendor specific information frame grouping in HDMI (High Definition Multimedia Interface) framework, and the permutation and combination of the 4th, judge that this image signal is the 3D signal of which kind of aspect, i.e. above-mentioned four bit representation 3D structures (3D-Structure).
For example, suppose above-mentioned four by a high position to low level permutation and combination for " 0000 " time, then this microprocessor 12 judges that the aspect of this image signal is as " imaged frame encapsulation ".Similarly, suppose above-mentioned four by a high position to low level permutation and combination for " 1000 " time, then this microprocessor 12 judges that the aspect of this image signal as " " about image side by side.Similarly, suppose above-mentioned four by a high position to low level permutation and combination for " 0110 " time, then this microprocessor 12 judges that the aspect of this image signal is as " image is side by side up and down ".
As shown in step S25 and step S26, if this current sequential data comprises this 3D form instruction data, then a current image format is set as the 3D form of this input signal by this microprocessor 12.If this current sequential data does not comprise this 3D form instruction data, then this current image format is set as 2D form by this microprocessor 12.In this preferred embodiment, this current image format is a variable being used for representing the image format of this image signal.That is, whether this microprocessor 12 can comprise this 3D form instruction data according to this current sequential data, this current image format is set as 3D form or the 2D form of this input signal.
As shown in step S27, this microprocessor 12 judge this current image format whether with a show image format match given tacit consent to.Wherein this show image form is defaulted as 3D form and the 2D form wherein one of this input signal.That is, the image format of the image frame of this display 13 of the show image style representatives of this acquiescence in display, this current image format then represents the image format of the image signal that this scale controller 11 has just received.
As shown in step S28, if this current image format and this show image format mismatching, be then this current image format by this show image format setting.That is, when the image format of image frame in showing is not identical with the image format of the image signal just received, it is this current image format by this show image format setting again that this microprocessor 12 is understood.
For example, suppose that this show image form is 2D form, and this current image format is 3D form, then this show image form can be reset to 3D form by this microprocessor 12.Similarly, suppose that this show image form is 3D image left and right side-by-side format, and this current image format is 3D image form side by side up and down, then this show image form can be reset to 3D image form side by side up and down by this microprocessor 12, and the image format making the image frame in showing is consistent with the image format of the image signal just received.
Again, if this current image format and this show image format match, the image format of image frame then in representative display is identical with the image format of the image signal just received, and therefore there is not image format inconsistent and cause this scale controller 11 cannot the problem of correct display frame.So this scale controller 11 will receive image signal constantly, recursively to carry out step of the present invention.
As shown in step S29, this scale controller 11 regenerates this image frame according to this show image form.This show image form is consistent with this current image format this moment, so this scale controller 11 is produced this image frame for the display of this display 13.
It is worth mentioning that, in step S23, although this image signal is in steady state (SS), if when this scale controller 11 not yet produces this image frame, then can carry out the following step S31 to step S34.
As stated in step s 31, this microprocessor 12 judges whether this current sequential data comprises this 3D form instruction data.Wherein the judgement details of this 3D form instruction data is as described by step S24, so repeat no more.
As shown in step S32 and step S33, if this current sequential data comprises this 3D form instruction data, being then the 3D form of this input signal by a show image format setting, if this current sequential data does not comprise this 3D form instruction data, is then 2D form by this show image format setting.
Because this scale controller not yet produces this image frame this moment, therefore there is not the problem that the image format of the image frame in display is inconsistent with the image format of the image signal just received.And this microprocessor 12 still needs to be the 3D form wherein one of 2D form or this input signal by this show image format setting, to produce foundation during image frame as this scale controller 11.
As shown at step s 34, this scale controller 11 produces this image frame according to this show image form.For example, suppose that this show image form is 2D form, then this scale controller 11 produces is the image frame of 2D form for the display of this display 13.Similarly, suppose that this show image form is 3D form, then this scale controller 11 produces is the image frame of 3D form for the display of this display 13.
From illustrating above, design of the present invention has following effect:
When this image signal is in steady state (SS), this microprocessor still can judge whether this current sequential data comprises this 3D form instruction data constantly, so that this current image format is set as 3D form or 2D form, and this show image form is mated with this current image format, this display is made can normally to export this image frame, and without the need to the connector that again plugged HDMI (High Definition Multimedia Interface) by user or restart this display device, so really object of the present invention can be reached.
