Figure 1 shows the three types of images that Bigshot can capture (click on the buttons to control the lens wheel setting). As you can see, the photos taken with the wide-angle lens and the stereo prism are not ready to be viewed by the user − they need to be processed to create panoramic and 3D photos, respectively. Bigshot's computer software applies the appropriate processing to each image after it is downloaded from the camera. The software also enhances the brightness, color and sharpness of the image. If the image is taken under lower light conditions and is noisy (grainy), the software can reduce the noise as well.
In general, the process of editing or modifying images is called image processing [1]. In this section, we look at a few basic image processing operations and how they alter the appearance of a photo.
