Embodiment Construction
[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein. Rather, the embodiments are provided to explain the principles of the invention and its practical application, thereby enabling others skilled in the art to understand the invention for various embodiments and with various modifications as are suited to particular intended uses.
[0029] The present invention proposes a kind of voice image acquisition coding method, comprises the following steps:
[0030] Step 1. The image in the video signal collected by the video signal acquisition module is composed of m rows and n columns of pixels in matrix form, and for each image pixel, it is positioned by the pixel coordinate value, such as figure 2 shown;
[0031] Step 2, when taking pictures, represent a c...

The invention discloses a voice image collection encoding method and device. The method comprises the steps that an image in a video signal collected by a video signal collection module is composed ofm rows of and n columns of pixels in a matrix form, and aiming at each image pixel, positioning is conducted through a pixel coordinate value; when photographing is conducted, image region coordinatevalues represent the specific area of one image, and coordinates of a scene in the image are judged according to the pixel sensing signal difference collected by the video signal collection module and the pixel coordinate values and the image region coordinate values; coordinate information of voice in the video signal is matched with coordinates of the scene in the image. Accordingly, by givingthe coordinate values to the voice, if corresponding television (TV) equipment is cooperated, when the video signal is played, the voice can be sent out from a corresponding display image scene actualarticulating region, particularly when the TV size becomes larger, the voice is not simply sent out from the bottom or the side face of the TV, the purpose that the voice moves on the TV along with the scenery is achieved, and the sense of immediacy of a video shooting site restores perfectly.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for collecting and encoding voice and image. Background technique [0002] The development of the flat panel display technology has made television (Television, TV) and other devices popular. TV is an audio-visual entertainment interactive device, which can not only display gorgeous images, but also emit beautiful voices that match it. Regarding the image and voice of TV currently on the market, its acquisition and encoding process is: image source → image acquisition device → analog-to-digital conversion → image encoding → digital image. [0003] When displaying on a TV, it is the reverse of the above process, that is, DAC (digital-to-analog conversion) is performed on the digital image, and then it is sent to the display module to display the image. For image acquisition, take a commonly used camera as an example, as follows: [0004] Whe...
