DIGIC III Image Processor
With DIGIC III, your images boast superior quality, the camera operates at top efficiency and battery life is enhanced. What's more, DIGIC III enables Canon's Face Detection Technology and Red-eye Correction to give you better, more true-to-life people shots. Simply press the Shutter Button halfway down, and the camera automatically pinpoints the faces in the scene and chooses the ideal focus point. The camera controls exposure settings and flash to keep every face looking bright and natural. Red-eye Correction can be handled in-camera, in two ways. The entirely new Red-eye Correction during shooting uses the Face Detection Technology to recognize and remove red-eye from flash images as they're taken, before the file is written to the memory card. It's also possible to correct red-eye during image playback, using simple settings in the A590 IS's menu.

Canon's powerful Face Detection Technology delivers even better results with the new A590 IS. The Face Detection Technology continues to recognize faces in a scene, and concentrate exposure (daylight or flash) and focus upon them. But the A590 IS adds more: Face Detection WB means the camera concentrates upon faces when calculating white balance for the best possible skin tones. Face Select and Track lets the A590 IS user highlight one face among several in a scene, and the camera concentrates on that person, even as they move around the scene. Face Detection Technology is a powerful contributing factor in Canon's new Motion Detection Technology.
Red-eye Correction provides three options for removing red-eye from subjects in flash pictures.
1) The new Red-eye Correction during shooting actually identifies and
corrects red-eye in human subjects as pictures are taken.
2) The A590 IS can be set to automatically detect and correct red-eye
during image playback.
3) The user can manually locate any red eyes in a scene during image
playback on the LCD screen, and command the camera to remove them.
The PowerShot A590 IS features ISO 1600 and High ISO Auto settings
that reduce the effects of camera shake and sharpen subjects in low-light
situations, giving you greater shooting flexibility.
