Umbriferous be not newly emerging things, a few this years nevertheless whole industry lies change level, traditional business teachs projector increment finite, and the occurrence as new light source and technology of new camera lens, intelligence is umbriferous make best-selling fractionize market with laser TV. As new leading role rise gradually, traditional projector brand some catch up with hard rhythm, their attention focus remains the good target such as resolution, brightness, really, these index are a foundation, but change ceaselessly as the demand of consumer, the market needs new innovation thinking.
Extremely although the history is not long,rice photograph compares the umbriferous brand at the tradition, but had sat at present throne of first of Chinese projector sales volume, make the brand that a few this years projector industry is worth to pay close attention to most. Extremely rice with innovation get victory, from intelligence umbriferous proceed with, outspread to laser TV, no matter be on product configuration, on the innovation that still is a technology, be worth commend very much. Such as is inputted automatically to anxious, speech wait for a function, extremely rice introduces actively among the product, the innovation that lets projector had new way.
Extremely rice in order to innovate no matter get victory is in on product configuration there still is contribution on technical innovation
In recent years, extremely rice is in MEMC technology and echelon make great efforts full on corrective technology, farther promotion intelligence is umbriferous pledge with the picture of laser TV and use rate easily. And traditional projector brand does not have a person to make too much success in these angle, actually this is the demand pain spot of consumer, the picture is abrupt fluent, the picture needs the troublesome issue such as mediation for many times, it is every consumer want to cast off " one ground chicken feather " .
The sketch map of MEMC technology
What is meant by MEMC technology? Let us speak of from the beginning.
When the person is watching an object, the object can be become on retina picture, input person head by optic nerve, form a vision, when the object removeds, optic nerve won't disappear instantly to the impression of the object, the time that second of meeting continuance 1/24 influences, so the film or teleplay, frame number should be in at least 24 frame, ability avoids what person eye perceives dynamic picture to interrupt.
How does MEMC technology insert frame
Via considering to discover, the limit of the dynamic picture that person eye can take is 55 frame, so video achieves the view image that 60 frame above can promote every second us apparently to experience, avoid person eye to feel high speed picture pulls the end, phenomenon that drop frame. This also is why Li An's director can use 120 frame technology to film " those who compare Li Linen is medium field war " reason, because of every second 120 frame are every second 5 times of 24 frame, use such filming that the technology can make a picture more lifelike, give a person one kind presumable the feeling that is like unreal.
The movie that at present we see and network video frame are led too won't tall, the reason has two sides: Suffer the regard that be confined to films and shows technology and cost, major film still industry of movie of the century on continue to use the making standard of 24 frame has every second the fluent sex that films; video website is broadcasted to assure online video, frame number is maintained basically also control in 25 frame, because this is in,broadcast the appears easily to shake and pull end phenomenon when picture of high speed motion, from " small screen " span arrives " big screen " hind these flaws still can magnify accordingly. To solve this problem, MEMC motion compensated a technology to appear.
This kind of technology forecasts algorithm through picture frame + frame generates algorithm, make judgement to the change of dynamic picture, computation the picture between two frame changes, build intermediate frame automatically, insert the means of frame through this kind, the video that leads low frame turns taller frame into the video of rate, those who solved fast dynamic picture shake and pull end, what add athletic picture considerably is fluent spend and definition.
Technology of MEMC motion compensation is not extremely rice original creation, but MEMC of the part on market was to use the method that inserts black frame, extremely the MEMC of rice forecasts algorithm through picture frame + frame generates algorithm, make judgement to the change of dynamic picture, build intermediate frame automatically between two frame, photograph comparing inserts black frame practice commonly, picture brightness nondestructive.
Some forecast calculative moment to make mistake easily
In the meantime, forecast to raise frame, the efficiency that frame generates, be in different advocate when the switch of setting, extremely the rate that rice promoted MEMC to intervene, when switch of the setting in improving an appearance considerably thereby, the accuracy that frame forecasts and efficiency, make this kind of process that insert frame more natural.
Can see, compare the MEMC skill at the tradition, extremely technology of compensation of rice MEMC motion achieved brilliance nondestructive, efficient wait for a characteristic. And the occurrence of this two big characteristics, to the user it is very practical. It is not dazzle ability, it is to solve a picture truly brightness and fluent " black science and technology " .
Extremely Wang Xin of CTO of rice science and technology expresses, "At present projector product carries these technologies rarely, basically have the reason of two respects, it is MEMC firstly athletic compensation technology is the true sport that will diagnose it through object character, but a few elements in the picture do not have such character, for instance TV station Logo, character, football, when these special elements appear in the picture, technology of MEMC motion compensation appears easily frame forecasts a mistake, cause indication picture occurrence error, and the accretion as indication picture, this kind of mistake is magnified more easily be aware of, increased MEMC motion to compensate a technology to be in greatly so umbriferous on applied difficulty because a lot of brands maintain profit to control cost,; is secondly, do not be willing to be in this above devoted cost. Do not be willing to be in this above devoted cost..
It is reported, extremely the MEMC exercise with better to let umbriferous equipment appear rice compensates a technology, the special element such as the football in combining oppose picture with MStar, character, LOGO undertook the algorithm of specific aim optimize, make its frame is forecasted more accurate, achieve the goal that makes umbriferous picture more fluent thereby, extremely the football mode of rice is this one child.
Contrail of line of competition ground ball is extremely changeful rice maintains sphere depart original campaign contrail
Contrail of line of competition ground ball is changeful, forecast the likelihood that insert frame to cause picture amlposition, extremely the football mode of rice, sphere depart, maintain original campaign contrail while, to the high speed of field, player motion is caught forecast, reproduce picture of real competition ground, make every time shoot clear and fluent. Besides MEMC motion compensates a technology, extremely rice still is in echelon is corrective the function is ceaseless research and development, reached brand-new level nowadays. In light of the sequence of thought that develops from the technology, extremely rice had realized intelligence auxiliary and corrective, this is current one of newest corrective technologies. In addition echelon is corrective and main cent uses fractionize market for two, the first be a tradition delivering a product, for instance intelligent projector; is the laser TV that uses reflection type to exceed brief anxious shot a kind. Compare for, latter echelon is corrective functional improvement is more complex.
Casting intelligence umbriferous:
In intelligence umbriferous domain, corrective technology experienced echelon fluctuation direction echelon direction of corrective, fluctuation is automatic echelon echelon is corrective, corrective at 4 o'clock, angle is portable echelon is corrective 4 acting gradual progress, extremely rice had developed echelon of the Five Dynasties nowadays corrective technology -- intelligence is auxiliary and corrective. Can say the progress of technology of the Five Dynasties, ceaseless gradual progress allows an user more save worry.
Echelon of the Five Dynasties is corrective functional gradual progress
From the evolution above the process can see, it is the simplest that intelligence assists corrective technology, did not learn cost, one key can adjust, to contemporary user, this ability is appropriate. Have a fever only friendly ability has idea to do adjust complexly, and average user wants to set one's mind at only read big screen content.
Different echelon is corrective functional sketch map
Reflection type exceeds TV of short anxious laser:
Perpendicular echelon is corrective
The low simple product of profit of on market a few pursuit uses the most primitive fluctuation to save cost (perpendicular) directional hand moves echelon corrective, the adjustment that controls to the picture can rely on shift or body of a favourable turn coming back to undertake only, so no matter be projectile curtain, projectile still Bai Qiang is very difficult the picture corrective arrive most the condition of Founder, appear extremely easily at the same time picture distortion.
Echelon is corrective at 4 o'clock
Traditional laser TV is used mostly echelon is corrective at 4 o'clock, can undertake to 4 horn in the picture corrective, but when direct and projectile Bai Qiang, the picture appears easily because of metope flatness problem distortion.
Echelon is corrective at 8 o'clock
Echelon is corrective at 8 o'clock
Extremely the professional figure that rice added an independence between laser TV handles chip, came true echelon is corrective at 8 o'clock function, when calculating projectile Bai Qiang, because metope is rough,rectify the picture twist that cause to also can go up through the picture 8 the dot has subtle shift school, let a picture become square upright and foursquare.
The one screen that take a picture is right neat
The one screen that take a picture is right neat
Cooperate extremely the picture vision with particular rice is algorithmic, APP of the assistant that do not have screen is added newly " the one screen that take a picture is right neat " function, according to APP the directive uses a mobile phone to taking a picture to TV wall curtain, can choose picture self-correcting limits to curtain casing inside, the laser TV that makes itself complex draws act adjustment job to become simple.
Because laser TV used reflection type to exceed brief anxious shot, because this is a few bigger on the difficulty with corrective echelon, join independent processing chip, ability is OK better let corrective function become simple use easily. Extremely rice considers this, because this was rolled out echelon is corrective at 8 o'clock function, subsequently development goes unique algorithm, form the one act that take a picture finally to be opposite neat advantage, this is the way that corrective function develops laser TV echelon.
Extremely the technology of MEMC motion compensation of rice and echelon are corrective although the technology is not original creation, but undertook be improvemented significantly on original basis. These two innovation can help an user use a product not only, more the investment that represented Chinese enterprise to innovate to projector technology and dedicated, also show Chinese umbriferous enterprise has begun to cast off the posture of blindly follow sb at the same time, oneself rhythm was had in family expenses domain. The author thinks extremely rice is locating from what join bureau new hand to industry navigate person role change, did not come in intelligence umbriferous domain and laser TV domain expect extremely rice can roll out more innovation.
