Canon’s DIGIC III processor introduces several advancements that reduce the risk of blurred or poorly exposed photographs. Face Detection AF/AE/FE automatically detects up to nine faces within a scene and optimises focus and exposure accordingly. Fast and highly accurate, the system has been enhanced on these models to control flash exposure (FE), and is now capable of detecting faces at greater distances. Face Detection Technology also enables Red-Eye Correction in playback. Users can quickly detect and remove red-eye in captured images directly in-camera, ensuring that people shots look natural and accurate. Noise Reduction Technology produces smooth images at up to ISO 1600, allowing for flash-free photography in dimly-lit areas such as parties and nightclubs. A new Auto ISO Shift function prevents blur by giving users the option to boost the ISO setting – and consequently shutter speed – with a single button press, whenever the camera predicts camera shake.
A range of enhancements has been made, based on feedback collected from users across the globe. Both cameras include new high resolution (230k pixels) PureColor LCD screens, which offer users a wide range of visual benefits. Colour tones have been enhanced by up to 30% for vibrant, true-to-life colour reproduction. The screen’s wide viewing angle is complemented by an anti-reflective coating, which makes it easy to compose and review images even in brightly-lit conditions. A scratch-resistant layer provides extra protection against knocks and scrapes.
Settings for shutter speed and aperture are now displayed on the LCD during shooting. When using Auto ISO and High ISO Auto, the LCD will also display the ISO speed. These camera settings are now recorded as EXIF data for review in playback. Users of the Digital IXUS 75 can instantly review captured images using a dedicated Playback button, which acts as a toggle between shooting and playback modes. The Print/Share button doubles as a customisable Shortcut button on both cameras, providing one-touch access to frequently used functions, such as movie recording or white balance settings.
A total of 17 shooting modes are provided, including a wide selection of Special Scene modes such as Portrait, Indoor and Night Snapshot. Digital IXUS 75 users can access modes via the Touch Control Dial. Both cameras include My Colors photo effects for creative experimentation before and after shooting.
A new Time Lapse Movie function allows users to capture changing scenes – such as drifting clouds, a blooming flower or a bustling city street – for accelerated playback as smooth VGA-quality movie clips. Captured at one-second or two second intervals, a scene of two hours’ duration can be condensed to a fluid eight minute or four minute movie file. Users can also record standard VGA movies with sound at 30fps and QVGA movies with sound at 60fps.
