Abstract
In an apparatus and a method for executing generation and reproduction processing of picture data suitable for picture display devices having differing processable frame rates, low frame rate picture data is generated on the basis of a plurality of temporally continuous pictures having a high frame rate to provide picture data having a plurality of layers. Decimated data may be set as the high frame rate layer data. In this manner, the quantity of data to be transmitted or stored is reduced.
Claims15
An image processing apparatus for generating frame data applicable to frame reproduction of differing frame rates, said apparatus comprising:
- frame conversion means for generating low frame rate frame data by averaging processing a plurality of temporally continuous frame data obtained at a high frame rate;
