Canon, which just two months ago took the wraps off a souped-up version of its best-selling Ixus Digital camera, has unveiled an improved basic model with some new functions. The Ixus Digital V replaces the original Ixus, which went on sale in June 2000, and will sit alongside the recently launched Ixus Digital 300 at the forefront of Canon's consumer digital still camera line-up. The new model shares much in common with the camera it replaces, including its size - the camera is roughly credit-card-sized and about 2.7 centimeters thick. It also has a 2-megapixel CCD (charge coupled device) pickup and 2x optical zoom like the original. Among the new features are a primary colour filter, a technology originally from Canon's Powershot G1 camera that also found its way into the Ixus Digital 300 model launched recently. The new filter replaces a CMYK (cyan, magenta, yellow, black) version used on the original model and will provide users with better colour reproduction, said Canon. An improved system for reducing image noise has also been added. An additional improvement brings the Ixus Digital V model in line with many other digital still cameras, because it can now record and play back movie clips with audio. Power consumption has also been reduced - by 40 percent, according to the company - which means a fully charged battery can support the capture of up to 120 images even with the built-in 3.5 centimeter (1.5 inch) LCD (liquid crystal display) turned on. Canon said it will go on sale in June for £450.
