Abstract
A method for processing the information of a still picture of high resolution displayed on a television screen is disclosed. The method includes the steps of receiving the picture information encoded by a pre-set encoding method, generating the averaging information specifying which interpolation is to be performed on the received picture information, decoding the picture information by a decoding method corresponding to the encoding method, storing the decoded picture information in a memory, reading out the stored picture information for processing the decoded picture information with interpolation, and outputting the interpolated picture information as a picture for display. An apparatus for carrying out the information processing method is also disclosed.
Claims15
A method for processing a picture, comprising the steps of:
- receiving picture information encoded by a pre-set encoding method;
- generating averaging information which specifies an interpolation method to be performed on the received picture information;
- decoding said picture information by a decoding method corresponding to said encoding method;
- storing the decoded picture information;
- reading out the stored decoded picture information stored for processing the decoded picture information with said interpolation method;
- outputting the interpolated decoded picture information as a picture for display;
- and
- thinning out the interpolated picture information for generating a reduced-size picture,
- outputting the reduced-size picture as a picture for display,
- wherein said decoded picture information is stored in a memory having a display region for storing a pre-set number of reduced-size pictures, and all of the reduced-size pictures stored therein are output as pictures for display each time said reduced-size picture is stored.
An apparatus for processing a picture, comprising:
- means for receiving picture information encoded by a pre-set encoding method;
- means for generating averaging information which specifies an interpolation method to be performed on the received picture information;
- means for decoding said picture information by a decoding method corresponding to said encoding method;
- memory means for storing the decoded picture information;
- means for reading out the decoded picture information stored in said memory means for processing the decoded picture information with said interpolation method;
- means for outputting the interpolated decoded picture information as a picture for display;
- and
- means for thinning out the interpolated picture information for generating a reduced-size picture,
- said outputting means outputting the reduced-size picture as a picture for display,
- wherein said memory means has a display region for storing a pre-set number of reduced-size pictures, said outputting means outputting all of the reduced-size pictures stored therein as pictures for display each time said reduced-size picture is stored.
