My module doesn't do anything except return a number and a list. Substitute these fixed values with your calculations.

CalcMean[data_] := Module[{EMean, MeanImg},
  EMean = 4;
  MeanImg = {{1, 2}, {3, 4}};
  {EMean, MeanImg}]; (*Dummy Module*)

{MeanX, RedMeanVec} = CalcMean[RedImg];

MeanX

4

RedMeanVec

{{1, 2}, {3, 4}}
