摘要： A first characteristic value extracting unit extracts a characteristic value from a picture transmitted from a transmission side, and a second characteristic value extracting unit extracts a characteristic value from a picture received on a reception side. These extracted characteristic values are supplied to a central monitoring unit through low speed lines, respectively. In the central monitoring unit, an MSE (mean square error) is assessed from the data by an MSE assessing unit. The first and second characteristic value extracting units divide an input picture into blocks, subject the blocks to an orthogonal transformation, or subject the blocks to PN sequence multiplication before the orthogonal transformation, and extract and output orthogonal transformation coefficients. The MSE assessing unit determines the differences between corresponding coefficients on the transmission side and the reception side and squares the differences, adds the squared differences for every coefficients or every blocks, and assess an MSE based on the added values referred to a table. With this operation, the MSE can be effectively assessed using a smaller amount of extracted data (accordingly, slower speed lines can be used in the central monitoring unit).

摘要： A sender produces a background video image 4 from a reference video image 1 and a depth map 3 and synthesizes the background video image 4 in a background buffer 5. A projection converting matrix 6 for synthesizing is calculated. A receiver receives the reference video image 1, the depth map 3 and the projection converting matrix 6. The receiver produces a free viewpoint video image 11 and a background video image 12. The background buffer 13 is dynamically renewed. The free viewpoint video image 11 and the image in the background buffer 13 are synthesized with each other, and the background video image in the concealed regions in the free viewpoint video image are complemented to obtain the complemented image 14.
