Abstract
The invention discloses a player capable of adaptively adjusting playing brightness. A brightness sensor is set to obtain the ambient light brightness of the player, the target playing brightness is obtained according to the parallel table of preset ambient brightness and playing brightness and the ambient light brightness, the brightness of each pixel of images in a playing stream of the player is adjusted according to the target playing brightness, the chromatic information of each pixel of the images in the playing stream is compensated, and the video subjected to brightness adjustment and chromatic compensation is played. The player is simple in structure and convenient to use, and can adaptively adjust the brightness of a playing frame to make the eyes of a viewer more comfortable, and prevent stimulating or harming the eyes when the ambient light is excessively dark.
Description
Technical field
The present invention relates to player field, particularly relate to a kind of player playing brightness self-adaptative adjustment.
Background technology
Player is to have broadcasting video or the electronic device product of audio file function.
Use the domestic consumer of media player (whether off-line player or network player) from January, 2000
33200000 surged to the 41700000 of January calendar year 2001.The professional user's quantity using media player at work was same for the most relatively last year
Phase rises 34.9%, increases to the 15700000 of January calendar year 2001 from the 11600000 of in January, 2000.The matchmaker of RealNetworks company
Body player not only uses domestic consumer and holds a safe lead in coverage rate, uses professional user's quantity of its player at work
Also it is in media distribution device user's usage amount seniority among brothers and sisters umber one with the crowd of 10,500,000.End January calendar year 2001, use
The professional user of RealNetworks media player rises 52.1% over the same period last year, and uses Windows at work
The professional user of two kinds of media players of Media Player and QuickTime rises 39.9%(900 ten thousand respectively) and 8.5%
(1,900,000).
The media player of RealNetworks share in the market increases, part will owing to it and America Online-
The agreement that Time Warner Inc.,TWX reaches.According to agreement, latest edition AOL6.0 being supplied to user at AOL Time Warner is soft
In part, RealPlayer is designated as unique built-in media player.After agreement signature, only last year 11, December two months
Just add the user of 5,100,000 to RealNetworks, and be added gradually to what RealPlayer " used main forces " by AOL
Number is also being continuously increased.While it is true, the market potential of RealPlayer is the biggest, according to issue January in this year
New statistics is estimated, RealPlayer player at least also has 25,000,000 domestic consumers and the market of 10,200,000 professional users "
Breach ".MP3 player and other compression audio player market are whether in marketing scale, or in terms of new product category
All constantly expanding.According to IDG (IDC) it is expected that the shipment amount worldwide compressing audio player will
Surging to 26,000,000 of 2005 from 3,300,000 in 2000, annual amplification is up to 51%.IDG (IDC) consumes
The triumphant fertile river in Henan Province of product market analysis man Susan is thought: the demand of the market player to broadcasting compacted voice file will expand further
Greatly.Owing to this player is many using flash memory (flash memory) as storage medium, and its high price, limited appearance
Amount, has made increasing retailer sight will be invested the media player that price is the most cheap, and this will be for new product development
Bring broader development space.Portable electronic device is by occuping market leading position, by 2005, this media play
The product turnout amount of device will account for the 61% of global media community player market.
IDG (IDC) in its Market Report issued it is also contemplated that, as Vehicular media player, can
The other type of media player such as the internet radio of played streaming media also will the most gradually occupy one seat.
Existing player can not be automatically adjusted picture brightness, can only manually regulate.
If ambient light is the most dim, the broadcasting brightness that the brightness of player plays picture with daytime is still is consistent,
So, on the one hand, human eye is in stimulation state, watch uncomfortable, cause poor user experience；On the other hand, light stings for a long time
The eyesight of human eye can be caused damage by sharp human eye.
Light intensity sensor is a kind of power sensing light and carries out the measurement apparatus showing, processing.It is made to complete many
Plant Experiments of Optics, such as compare the relation of light intensity and distance；The research interference of light, diffraction, polarization；Light is measured under different light sources
Relatively strong and weak；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, after RC Lecraw proposes about the research report of magneto-optic effect, cause 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 excellent electricity
The characteristics such as insulating properties and anti-interference, frequency response width, fast, the safety anti-explosive of response, the therefore survey to some special occasions electromagnetic parameters
Amount, has effect of uniqueness, especially in terms of the measurement of the big electric current of power system mesohigh, more show the advantage that it is potential.Simultaneously
Software and hardware by 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 is in sensitivity, work
Make scope aspect and have different abilities.Along with high-performance laser in recent decades and the appearance of novel magnet-optical medium,
The performance of magneto-optic effect sensor is increasingly stronger, applies 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 partially
When the light that shakes 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
Degree, here it is magneto-optic effect.Namely can measure additional magnetic field by the angle rotated.At specific experimental rig
Under, 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, is used for measuring specific physical quantity.
