regions of the image, and then compresses the regions of the
image by a degree of data compression dependent on the image
activity value for each region.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. Video data compression apparatus comprising:
(i) means for detecting image activity values indicative
of image activity for regions of an input image to be
compressed;
(ii) means for filtering said detected image activity
values to reduce the variation in image activity values
between groups of adjacent regions of said image; and
(iii) means for compressing said regions of said image by a
degree of data compression dependent on said image activity
value for each region.
