Abstract:
An apparatus includes a filter circuit and an encoder. The filter circuit may be configured to (i) calculate a noise level of a frame of a video signal based on a subset less than all of a plurality of blocks of the frame, where each of the blocks in the subset may have an associated weighted activity to variance ratio that exceeds a threshold value and (ii) generate a filtered video signal based on the noise level. An estimated noise level of each of the blocks in the subset may be selected from one of (a) an activity of the block, (b) another activity of a reference block of another frame and (c) a sum of absolute pixel differences between the block and the reference block. The encoder may be configured to generate a bitstream by encoding the filtered video signal.

Claim (Index 4):
The apparatus according to  claim 1 , wherein (i) the filter circuit is further configured to mark individual blocks of the frame as saturated responsive to a determination that the individual blocks have a (a) minimum pixel intensity, (b) maximum pixel intensity or (c) average pixel intensity that is outside a saturated pixel intensity range and (ii) the individual blocks marked as saturated are excluded from the calculation of the noise level.
