Description
Technical field
The present invention relates to technical field of image processing, in particular, being related to a kind of phonetic image acquisition coding method and dress
It puts.
Background technology
The development of flat panel display so that the equipment such as television set (Television, TV) are popularized.TV is audio-visual
Interactive device is entertained, can not only show gorgeous image, moreover it is possible to send out matching graceful voice.About current market
TV image and voice, acquisition and cataloged procedure be：Image source → image collecting device → analog-to-digital conversion → image coding
→ digital picture.
Then it is the reverse of above-mentioned flow when being shown on TV, i.e., DAC (digital-to-analogue conversion) is carried out to digital picture, then convey
Display image after on to display module.For Image Acquisition, by taking common photographing camera as an example, carry out as described below：
When taking pictures to scenery, the photosensitive Sensor of camera CCD/CMOS (video signal collection module) are (hereinafter referred to as
Sensor) photosensitive to scenery, since the intensity of scenery different zones light and the color of light are different, then photoreceptor corresponding region is felt
The signal that should be generated is also different, thus records captured scenery color and luminance information；Meanwhile the scape in scenery
Position is also recorded together.
Scenery has correspondence with Sensor, and scene image corresponds to multiple Sensor Pixel (hereinafter referred to as respectively
Pixel), simultaneously because Pixel is regularly arranged in Sensor, you can according to Pixel coordinate informations to the scape in scenery
Position positioned.
Meanwhile voice collecting in video and the process of coding are：Speech source → voice acquisition device → analog-to-digital conversion →
Voice coding → digital speech.Then it is the reverse of above-mentioned flow when needing voice playback, i.e., DAC (numbers is carried out to digital speech
Mould is converted), then be transported on loud speaker (Speaker) and play out.
It is taken pictures using camera, is simple acquisition image；It is recorded using microphone, is simple acquisition voice；
When being cooperated simultaneously using camera and microphone, phonetic image, that is, video just produces.Traditional vision signal
Include：Picture signal, voice signal, synchronizing signal, but the coding mode of its image and voice messaging is simple, image and voice
The content of information is single, it is impossible to well to onlooker really come personally perception.
Invention content
In view of the drawbacks described above of the prior art, the technical problems to be solved by the invention are to provide a kind of phonetic image and adopt
Collect coding method and device, by changing the coding mode of image and voice messaging, further rich image and voice messaging
Content, to onlooker more really come personally perception.
To achieve the above object, the present invention provides a kind of phonetic images to acquire coding method, includes the following steps：
