The original three megapixel PowerShot G1 was announced at Photokina 2000 (September 2000), just less than a year later (August 2001) they announced the four megapixel PowerShot G2 with a fairly significant range of improvements. A year after that at Photokina 2002 Canon announced the new four megapixel PowerShot G3, with a sleek new body design, new control layout and image processor and four times optical zoom lens.

- DiGiC processor - a new processor which is responsible for
CCD control, AE/AF/AWB, signal processing, JPEG compression, memory
card control, LCD monitor display).
- Intelligent Scene Analysis based on Photographic Space (iSAPS)
- Camera uses variables such as focus distance, exposure brightness
and cross references these against a large internal database of known
scene types and uses this information to optimize image processing.
- Flexible AF point selection - You can now select from any one of more than 300 positions around the image frame.
