Abstract
The invention discloses an adaptive adjustment method for play brightness of a player. Firstly, a light intensity sensor is disposed to obtain light ray brightness of environment in which a player is, objective play brightness is obtained then according to preset environment brightness, a play brightness comparison list and the environment light ray brightness, brightness of each pixel of a picture in a play flow of the player is adjusted then according to the objective play brightness, compensation is performed on chroma information of each pixel of the picture in the play flow, and a video after brightness adjustment and the chroma compensation is player finally. The method has the advantages of simple design and convenient usage, brightness of play frames of the player can be adaptively adjusted, human's eyes are in a comfortable state, and the human's eyes are prevented from being stimulated and damaged when environment light rays are too dark.
Description
Technical field
The present invention relates to player field, a kind of method particularly relating to player plays brightness self-adaptative adjustment.
Background technology
Player is the electronic device product having and playing video or audio file function.
The domestic consumer using media player (whether off-line player or network player) surged to the 41700000 of January calendar year 2001 from the 33200000 of in January, 2000.The professional user's quantity using media player at work also rises 34.9% over the same period last year, increases to the 15700000 of January calendar year 2001 from the 11600000 of in January, 2000.The media player of RealNetworks company not only uses domestic consumer and holds a safe lead in coverage rate, uses professional user's quantity of its player to be also in media distribution device user with the crowd of 10,500,000 at work and makes consumption ranking list first.End January calendar year 2001, the professional user using RealNetworks media player rises 52.1% over the same period last year, and uses the professional user of two kinds of media players of WindowsMediaPlayer and QuickTime to rise 39.9%(900 ten thousand respectively at work) and 8.5%(190 ten thousand).
The media player of RealNetworks share in the market increases, the agreement that part to be reached with AOL Time Warner Inc. owing to it.According to agreement, it is supplied in the latest edition AOL6.0 software of user RealPlayer at AOL Time Warner and is designated as unique built-in media player.After agreement signature, only last year 11, December just add the user of 5,100,000 for two months to RealNetworks, and are added gradually to the number of RealPlayer " use main forces " by AOL and are also being continuously increased.While it is true, the market potential of RealPlayer is still very big, according to issue January in this year recent statistics data estimation, RealPlayer player at least also has the market " breach " of 25,000,000 domestic consumers and 10,200,000 professional users.MP3 player compresses audio player market whether in marketing scale with other, or all in continuous expansion in new product category.According to IDG (IDC) it is expected that worldwide compress the shipment amount of audio player and will surge to 26,000,000 of 2005 from 3,300,000 in 2000, annual amplification is up to 51%.The triumphant fertile river in Henan Province of IDG (IDC) consumer product market analyst Susan is thought: the demand of the market player to broadcasting compacted voice file will expand further.Owing to this player is many using flash memory (flashmemory) as storage medium, and its high price, limited capacity, having made increasing retailer sight will be invested the media player that price is more cheap, this will bring broader development space for new product development.Portable electronic device is by occuping market leading position, and by 2005, the product turnout amount of this media player will account for the 61% of global media community player market.
IDG (IDC) in the Market Report of its issue it is also contemplated that, as Vehicular media player, the other type of media player such as internet radio of played streaming media also commercially will can occupy one seat gradually.
Existing player can not be automatically adjusted picture brightness, can only manual adjustments.
If ambient light is excessively dim, the broadcasting brightness that the brightness of player plays picture with daytime is still is consistent, then, on the one hand, human eye is in stimulation state, watches uncomfortable, causes poor user experience；On the other hand, light stimulates human eye can the vision of human eye be caused damage for a long time.
Light intensity sensor is a kind of power sensing light the measurement apparatus displaying, processing.Make it can complete multiple Experiments of Optics, such as compare the relation of light intensity and distance；Research interference of light, diffraction, polarization；The relatively strong and weak of light is measured under different light sources；Bright, the dark change etc. of the different light source of research.It is usually used in biology, chemical experiment.
From the end of the sixties, RCLecraw proposes about, after the research report of magneto-optic effect, causing everybody attention.Japan, the country such as Soviet Union has all carried out research, and domestic also have scholar to explore.The sensor of magneto-optic effect has the characteristic such as excellent electrical insulation capability and anti-interference, frequency response width, fast, the safety anti-explosive of response, therefore the measurement to some special occasions electromagnetic parameters, there is effect of uniqueness, especially in the measurement of the big electric current of power system mesohigh, more show the advantage that it is potential.Simultaneously by the software and hardware of development process system, it is also possible to realize the automatic real-time measurement of electric welding machine and robot control system.In the use of magneto-optic effect sensor, it is most important that selecting magnet-optical medium and laser instrument, different devices has different abilities in sensitivity, working range.Along with the appearance of high-performance laser in recent decades and novel magnet-optical medium, the performance of magneto-optic effect sensor is increasingly stronger, applies also more and more extensive.
The principle of magneto-optic effect sensor realizes the function of sensor mainly by the polarization state of light.When a branch of polarized light is by medium, if there is an external magnetic field in direction of beam propagation, then light will rotate an angle by plane of polarization, here it is magneto-optic effect.Namely can measure additional magnetic field by the angle rotated.Under specific assay device, the angle of deflection and the light intensity of output are directly proportional, and penetrate laser diode LD by output illumination, it is possible to obtain digitized light intensity, are used for measuring specific physical quantity.
