Ben Pritchard ещё в позапрошлом году очень неплохой вариант сделал:

import flash.display.BitmapData;

class RedEyeReducer{

	//Ben Pritchard 2005

	

	//Bitmap Data Object

	private var pBMP:BitmapData;

	//Input Mc

	private var mc:MovieClip;

	//Tolerances

	private var toleranceRed:Number;

	private var toleranceGreen:Number;

	private var toleranceBlue:Number;

	

	function RedEyeReducer(){

	}

	

	//Apply tolerances

	public function setColorTolerance(r:Number,g:Number,b:Number):Void{

		toleranceRed = r;

		toleranceGreen = g;

		toleranceBlue = b;

	}

	

	//Sets the mc to use for reduction

	public function setPictureClip(mc:MovieClip):Void{

		trace("MC " + mc);

		mc.cRef = this;

		//Creates the overlay

		mc.createEmptyMovieClip("shade_mc", 2);

		//Track the click and drag

		mc.onPress = function(){

			this.shade_mc.moveTo(this._xmouse, this._ymouse);

			this.origX = this._xmouse;

			this.origY = this._ymouse;

			this.drawing = true;

			

		}

		//Redraw the overlay

		mc.onMouseMove = function(){

			if(this.drawing == true){

				this.shade_mc.clear();

				this.shade_mc.moveTo(this.origX,this.origY);

				this.shade_mc.beginFill(0xFFFFFF,50);

				this.shade_mc.lineTo(this._xmouse, this.origY);

				this.shade_mc.lineTo(this._xmouse, this._ymouse);

				this.shade_mc.lineTo(this.origX, this._ymouse);

				this.shade_mc.lineTo(this.origX, this.origY);

				this.shade_mc.endFill();

			}

		}

		mc.onRelease = function(){

			//Record the coordinates

			this.endX = this._xmouse;

			this.endY = this._ymouse;

			//Clear the overlay

			this.shade_mc.clear();

			//Turn the overlay updating off

			this.drawing = false;

			//Create the bitmap object

			var transparent:Boolean = true;

			var fillColor:Number = 0xFFFFFFFF;

			this.cRef.pBMP = new BitmapData(this._width, this._height, transparent, fillColor);

			this.cRef.pBMP.draw(this);

			this.attachBitmap(this.cRef.pBMP,1);

			//Call the reduction method

			this.cRef.setRedtoBlack(this.origX,this.origY,this.endX,this.endY);

		}

	}

	

	private function setRedtoBlack(origX,origY,endX,endY):Void{

		//Loop through the coordinate colors

		trace(toleranceRed);

		for(var i:Number= origX;i< endX;i++){

			for(var j:Number = origY;j < endY;j++){

				if(parseInt(pBMP.getPixel(i,j).toString(16).substring(0,2),16) > toleranceRed && parseInt(pBMP.getPixel(i,j).toString(16).substring(2,4),16) < toleranceGreen && parseInt(pBMP.getPixel(i,j).toString(16).substring(4,6),16) < toleranceBlue){

					var currentColor = "0x" + "00" + pBMP.getPixel(i,j).toString(16).substring(2,6);

					pBMP.setPixel(i,j,currentColor);

				}

			}

		}

	}

	

	public function reset():Void{

		pBMP.dispose();

	}

}

Вот тут можно посмотреть как это работает:
