In order to function well, a robot is equipped with various sensors to acquire information about its sorroundings, one of which is visual sensor using digital camera. Since it will be used for basis in determining the action to be performed, the information has to be develop software for real yime imagine processing using computer employing web cam for imagine acquisition. The operations that could be performed by the software is brightness modification, negative, color element extraction, conversion from color image to grayscale, thresholding, smoothing, sharpening, edge detection, and histogram calculation. The results of the test using computer with 1.4 GHz Pentium IV Centrino processor showed that the processing time per frame of the images gathered from web cam depended on the type of the operation, especially on the complexity of the calculation as well, as number of pixels used to determine the value of the resulted pixel. In this research, it was found that the processing speeds of those operations were ranged from 5 ms for operations involving single pixel up to 123 ms for operation involving 169 neighboring operations up to 30 fps for point operations.
