The PowerShot G2's 4 megapixel CCD provides high resolution for prints that are comparable to the products of fine 35mm cameras. This increase in resolution produces a dramatic difference in image quality over the standard 2 megapixel class cameras. The CCD is also equipped with primary color filters (RGB) for superior color reproduction. While in the past, primary color filters caused images to be somewhat noisier than complementary color filters, the G2 includes a new IC with improved signal processing to compensate for this. So images are not only rich in detail but also include true-to-life color, and lower noise levels than ever.
