Embodiment
Existing DLP projector and color sequential display are easy to generate the rainbow effect.
In view of this, embodiments of the invention provide the device that can improve the rainbow effect.The rainbow effect degree that the device that improves the rainbow effect can automatically be detected video pictures and produced.When rainbow effect degree during greater than pre-set threshold value, the device that improves the rainbow effect can automatically be adjusted the one of which parameter of picture update rate of colour wheel rotating speed and the vision signal of colour wheel device.Can automatically improve the rainbow effect degree of video pictures thus.Set forth embodiments of the invention in detail below with reference to accompanying drawing, the for example clear example embodiment of the present invention of accompanying drawing, the wherein same or similar element of same tag indication.
Fig. 1 is the synoptic diagram of a kind of projector of one embodiment of the invention.Please with reference to Fig. 1, projector 10 comprises device, light source 80, the colour wheel device 90 and digital micromirror elements (digitalmicro-mirror device, DMD) 100 that improves the rainbow effect.The device that improves the rainbow effect can comprise estimating apparatus 20, discriminating gear 30 and control device 40.The device that improves the rainbow effect also can comprise storage device 50, input media 60 and chromacoder 70.Estimating apparatus 20 connects discriminating gear 30.Discriminating gear 30 connects control device 40.Control device 40 connects storage device 50, chromacoder 70 and colour wheel device 90.Chromacoder 70 connects input media 60 and digital micromirror elements 100.
Estimating apparatus 20 can be used to estimate the rainbow effect degree that video pictures produces.Because rainbow effect degree is that the people watches a kind of visual experience that video pictures produces, along with the object of seeing is different, its rainbow effect degree of experiencing also can be different.The estimating apparatus 20 of present embodiment can be used to assess the rainbow effect degree that most of people experience video pictures, and rainbow effect degree is quantized to make things convenient for back-end circuit to handle.Whether discriminating gear 30 can compare rainbow effect degree and the pre-set threshold value after quantizing, serious with the rainbow effect degree of differentiating video pictures.When the rainbow effect of video pictures was too serious, control device 40 can carry out parameter adjustment of each device, alleviates the rainbow effect.For instance, control device 40 can be adjusted the rotating speed of colour wheel device 90, and also 70 couples of vision signal VS of may command chromacoder change, the picture update rate of adjustment video pictures.
Fig. 2 A is the synoptic diagram of a kind of estimating apparatus of one embodiment of the invention.Please jointly with reference to Fig. 1 and Fig. 2 A, estimating apparatus 20 can comprise image capture unit 201 and image processor 202.Image processor 202 connects image capture unit 201 and discriminating gear 30.Image capture unit 201 for example be charge-coupled image sensor (Charge-coupled Device, CCD) or complementary metal-oxide layer-semiconductor (Complementary Metal-Oxide-Semiconductor, CMOS) sensor devices.Image capture unit 201 can be used to capture and is projected in the video pictures on the screen 110 and offers image processor 202.Image processor 202 can be analyzed video pictures, to quantize the rainbow effect degree that video image is produced.
For instance, Fig. 2 B is the synoptic diagram of the video image that a kind of image capture unit captured of one embodiment of the invention.Suppose that projector 10 is that projection in regular turn goes out red picture, green picture and blue picture, and the continuous video picture there is the round C10 of a white to move from the left side toward the right.The video pictures that image capture unit 201 is captured is shown in Fig. 2 B, and wherein zone C 1 presents redness, and zone C 2 presents white, and zone C 3 presents cyan.Image processor 202 can be differentiated rainbow effect degree according to the zone C 1 and the ratio of zone C 2, but the present invention is not as limit.In other embodiments, those skilled in the art also can come the rainbow effect degree of quantitation video picture in different ways.For example also the ratio of Free Region C1 and zone C 3 is differentiated rainbow effect degree.
Fig. 3 is a kind of synoptic diagram that improves the method for rainbow effect of one embodiment of the invention.Please jointly with reference to Fig. 1 and Fig. 3, at first can be by step S301, estimating apparatus 20 can be estimated the rainbow effect degree that video pictures produces, and the rainbow effect degree after will quantizing is exported to discriminating gear 30.Then can be by step S302, whether whether the rainbow effect degree after discriminating gear 30 differentiations quantize is greater than pre-set threshold value, too serious to differentiate the rainbow effect; If not, but subsequent steps S303, projector's 10 normal runnings; If, but subsequent steps S304.Those skilled in the art can be according to the size of its requirement definition pre-set threshold value.
Accept above-mentionedly, in step S304, control device 40 can be adjusted the one of which parameter of picture update rate of colour wheel rotating speed and the vision signal VS of colour wheel device 90.For instance, in the present embodiment, suppose that the vision signal kind is composite video broadcast singal (Composite Video Broadcast Signal; CVBS); Its picture update rate is 50Hz, its standard be line-by-line inversion (Phase Alternating Line, PAL).It is 3 times of rotating speeds that control device 40 can promote the colour wheel rotating speed of colour wheel device 90.Projector 10 also can adjust other parameters according to the rotating speed of colour wheel device 90 adaptively.Can effectively reduce the rainbow effect thus.
But subsequent steps S305 after step S304, whether the rainbow effect of discriminant parameter adjustment rear video picture is less than pre-set threshold value, and detailed implementation step can be with reference to step S301, S302.If the rainbow effect still greater than pre-set threshold value, can be got back to step S304 and adjust other parameters again.If the rainbow effect is less than pre-set threshold value, but subsequent steps S306, the parameter preset that control device 40 is stored in adjusted parameter in the storage device 50 and is adopted during as projector's 10 operations.
Above-mentioned steps S304 only is a kind of selection embodiment, and the present invention is not as limit.For instance; In another embodiment; Suppose that the vision signal kind is analogy colour difference signal (YPbPr); Its picture update rate is 60Hz, and its standard is the colourcast standard that National Television System Committee's (National Television SystemCommittee is abbreviated as NTSC) formulates.In addition, suppose to be limited to 150 revolutions per seconds on the rotating speed of 90 ability supports of colour wheel device.In the present embodiment, be 3 times of speed if control device 40 direct rotating speeds with colour wheel device 90 increase, can exceed the hardware limit of colour wheel device 90.So step S304 in the present embodiment, control device 40 may command chromacoders 70 make its picture update rate with vision signal VS convert 50Hz into by 60Hz.Then control device 40 can be 3 times of rotating speeds with the rotating speed lifting of colour wheel device 90.Can in the hardware limit scope of colour wheel device 90, reach the purpose that reduces the rainbow effect thus.
Again for example, in another embodiment, suppose that the vision signal kind is HDMI signal (High Definition Multimedia Interface is called for short HDMI), its picture update rate is 24Hz.In addition, suppose to be limited to 150 revolutions per seconds on the rotating speed of 90 ability supports of colour wheel device.Step S304 in the present embodiment, control device 40 may command chromacoders 70 make its picture update rate with vision signal VS carry out process of frequency multiplication, make it convert 48Hz into by 24Hz.Then control device 40 can be 3 times of rotating speeds with the rotating speed lifting of colour wheel device 90.Can in the hardware limit scope of colour wheel device 90, reach the purpose that reduces the rainbow effect thus.
