Abstract
By one approach a control circuit receives video information to be encoded, uses a particular rounding control value when processing the video information, and detects when color banding occurs when processing the video information using the particular rounding control value and responsively reprocesses the video information using a different rounding control value. By another approach, the control circuit has a plurality of different intra prediction types, including a planar intra prediction type, available to use when encoding the video information and wherein the control circuit determines when the planar intra prediction type can be employed without testing use of all of the plurality of different intra prediction types. By yet another approach, the control circuit selects block coding parameters, at least in part, by comparing corresponding mode costs, detects a smooth area in the video information, and then modifies mode costs as a function of having detected the smooth area.
