This is my code.

 import cv
 import numpy as np
 img=cv.imread("D:\OpenCV2.2\doc\logo.png",1)
 hsv=cv.CreateImage(cv.GetSize(img),8,3)
 cv.CvtColor(img,hsv,cv.CV_BGR2HSV)
 mas=cv.CreateImage(cv.GetSize(img),8,1)
 cv.InRangeS(hsv,(110,50,50),(130,255,255),mas)
 res=cv.CreateImage(cv.GetSize(img),8,1)
 cv.bitwise_and(img,img,res,mask=mas)

This is the error I get: Traceback (most recent call last): File "<pyshell#10>", line 1, in <module> cv.bitwise_and(img,img,res,mask=mas) TypeError: Scalar value for argument '<unknown>' is longer than 4

first of all, please use cv2, not the outdated cv module. (cv was completely removed in opencv3)

 import cv2
 import numpy as np
 img = cv2.imread("D:/OpenCV2.2/doc/logo.png", 1)
 hsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)
 mask = cv2.inRange(hsv, (110,50,50), (130,255,255))
 res = cv2.bitwise_and(img, img, mask=mas)
