First Claim
Patent Images
1. A method for forming an input image sequence, said method comprising the steps of:
- (a) defining a region of interest, wherein said region of interest is defined in accordance with a detected audio signal;
(b) obtaining a higher resolution of said defined region of interest to form a component of the input image sequence; and
(c) applying said input image sequence to an encoder.
