Abstract
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.

Total Claims: 17
Claim 1
Independent Claim
146 words
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.
Claim 2
Independent Claim
146 words
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.
