1 Development Background
1–1 Development Objectives
The PowerShot G2, which went on sale in the fall of 2001 as the successor to the PowerShot G1, won very high
acclaim from the market for its high degree of perfection covering “picture quality”, “functionality” and “design”.
As a result, the camera achieved a stable demand from both advanced “artistically oriented” amateurs and
industry users looking for “dependability”. Therefore, it is vital that the next model to the PowerShot G2 aim for
even more enhanced performance while continuing this concept.
With this background in mind, we initiated development of the PowerShot G3, as the top model of the PowerShot
series, with a new built-in large-diameter 4x zoom lens and DIGIC (Digital Imaging Processor) to get the most
out of the enhanced high picture quality generated by the 4-megapixel CCD and the primary color filter.
Furthermore, the PowerShot G3 will aim for a different evolutionary path by adding bracketing features and
end-sync photography to provide “the finest picture quality with the foremost functions”.
1–2 Product Concepts
The PowerShot G3, successor to the PowerShot G2, aims to be the top in its class in terms of picture quality by
employing a 1/1.8-inch, 4-megapixel-class CCD and incorporating a newly developed f/2.0 (wide-angle) “large-
diameter lens” with four-times zoom capability and the “DIGIC (Digital Imaging Processor)”, which provides
enhanced high-quality image processing functions. In terms of function, the product concept has included
specifications so that advanced amateurs and semi-professionals can take full advantage of sophisticated camera
techniques.
The PowerShot G3 is also equipped with the “My Camera” feature of the PowerShot S30/S40 and IXY Digital
300a models, and adds new “creation of on-camera content” capability.
