Background transformation apparatus using mask image and its method

1. the art that the invention defined in the claims The present invention will on a computer-readable recording medium recording a program for realizing the above method and the background modulation apparatus and method using the mask image of the human region. 2. The invention attempts to solve the technical challenges The invention From zone after determining the region status belonging to the zone to calculate the gain for each area of ​​the input image (the person area or a background area) to generate a mask image (for example, the speaker area) for modulating the background image, to provide a computer readable recording medium having a program for realizing the above method and the background modulation apparatus and method using the mask image of the person area computer that purpose. 3. Resolution of the subject matter of the invention, The present invention, in the background modulation device, tied pixels in the frames of image which is input from the outside to generate a meaningful region area dividing means for dividing a frame; The area dividing unit area state belongs to the region by calculating the gain of the respective regions divided from (the person area or a background area), the decision by extracting human region for generating a mask image for the human region extracted said After extracting the human region Way; And including a background image modulation means for using the mask image generated by the person area extracting device to modulate a background image. 4. An important use of the invention, The invention yiyongdoem oil or the like. The wireless video phones or biometric systems. Background modulation, area division, the speaker area extraction, area gain calculation, determining region condition, mask image, video phone
