Problems solved by technology

[0012] In addition, in the method described in Japanese Unexamined Patent Publication No. 11(1999)-259640, since the toning data is generated for every several frames, the processing speed is low if high-precision devices are not used.
As a result, the device size becomes larger

Embodiment Construction

[0097] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 A block diagram showing the configuration of a dynamic image transmission system using a dynamic transmission server employing the dynamic image conversion device and the dynamic image transmission device of the first embodiment of the present invention. Such as figure 1 As shown, the moving picture transmission system in the first embodiment includes a moving picture transmission server 1 storing a moving picture data set M0 generated by a moving picture content generating device such as a personal computer 2 . When a portable terminal 3 such as a mobile phone, PHS or PDA requests transmission of any moving picture data set from the server 1 through the mobile phone communication network, the requested moving picture data set M0 is sent from the moving picture transmission server 1 to the terminal 3 .

[0098] The dynamic image transmission server 1 includes a ...

Abstract

A continuous frame-by-frame image display as a reduced-color moving image can be carried out in high quality on a high-resolution display device of a mobile terminal or the like. A request reception unit receives a moving image transfer request from the terminal, and a model judgment unit judges the model of the terminal. A moving image format conversion unit converts moving image data into a format corresponding to the model. If the terminal cannot carry out moving image display but can display a multimedia image wherein frames are continuously displayed one by one in high quality, a moving image conversion unit converts the moving image data into multimedia image data. At this time, a data size limit and the like of the terminal are considered. An image transmission unit sends the multimedia image data to the terminal.

Description

technical field [0001] The invention relates to a method for converting dynamic images into FLASH TM A dynamic image conversion device and method for multimedia images such as movies, and a dynamic image conversion device and method for converting a dynamic image into a reproduced color dynamic image. The present invention also relates to a moving image transmission device and method for transmitting moving images to a portable terminal and the like, and to a program for causing a computer to execute the moving image conversion method and the moving image transmission method. Background technique [0002] Images taken by digital cameras, scanners, etc. can represent 24-bit colors (ie, about 16.77 million colors), where each 8 bits are designated as R, G, and B. However, some reproduction devices can only reproduce a few colors, such as 256 colors. Also, image formats commonly used in URLs such as GIF or PNG can only handle 256 colors. Therefore, in order to display an ima...
