摘要： A data structure of an image signal includes a reproduction cycle identifier indicating whether the cycle of image display for each frame is variable or not. When the display cycle identifier indicates that the display cycle is fixed, display cycle data is inserted in a header of the coded image data, and data relating to the frame number is inserted in each frame. On the other hand, when the display cycle identifier indicates that the display cycle is variable, display time data is inserted for each frame. Therefore, when decoding and displaying the coded image data having a fixed display cycle, the decoded image data can be displayed by a simple circuit structure, i.e., based on the display cycle data and the frame number data having a relatively small data quantity (bit number), without referring to the display time data having a relatively large data quantity for each frame. Furthermore, this data structure can be applied to a coded image signal having a variable display cycle.

摘要： An image processing method for dividing a digital image signal into plural image signals corresponding to plural blocks constituting a single display screen, and performing block-by-block coding of the image signals of the respective blocks, comprises transforming an image signal of a coding target block to be subjected to coding into frequency components by frame-by-frame frequency transformation on a frame basis or field-by-field frequency transformation on a field basis; setting a processing order for coding the frequency components corresponding to the image signal of the coding target block, according as the image signal of the coding target block has been subjected to the frame-by-frame frequency transformation or the field-by-field frequency transformation; and successively coding the frequency components corresponding to the image signal of the coding target block according to the order which has been set. Therefore, in coding of an interlaced image or a specific progressive image in which frame DCT blocks and field DCT blocks coexist, a run length is increased, thereby improving coding efficiency.
