DIGIC 4 Image Processor With DIGIC 4, your images boast superior quality, the camera operates at top efficiency and battery life is enhanced. What's more, the DIGIC 4 Image Processor enables Canon's Face Detection, Motion Detection Technologies 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. The camera also selects and sets the optimal exposure and ISO settings automatically to keep everything looking sharp and clear. Red-eye Correction can be handled in-camera, in two ways. The Red-eye Correction during shooting uses the Face Detection Technology to recognize and remove red-eye from 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 PowerShot SX120 IS menu.

iSAPS Technology is an entirely original scene-recognition technology developed for digital cameras by Canon. Using an internal database of thousands of different photos, iSAPS works with the fast DIGIC 4 Image Processor to improve focus speed and accuracy, as well as exposure and white balance.

DIGIC 4 features Face Detection Technology, giving you the best possible results in any shooting situation. Face Detection AF/AE sets the focus point and exposure for the faces of your subjects. Face Detection FE adjusts the flash to correctly illuminate your subject to provide the best balance between your subject and the overall scene, eliminating the common problems of over and underexposed faces.
Face Detection WB means the camera concentrates upon faces when calculating white balance for the best possible skin tones. Face Select and Track lets you 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 Motion Detection Technology.
Simply press the Face Selector Button, then the selected face is double-framed and tracked when the face moves in the frame.
Motion Detection Technology works in the background to instantly evaluate how fast your subject is moving. It automatically selects and sets the optimal exposure and ISO settings to keep everything looking sharp and clear. This feature provides higher ISOs when you need it for action-stopping shutter speeds. But when no movement is detected, it sets lower ISOs for excellent color and detail.
Life doesn't give you second chances to capture special times. That's why the PowerShot SX120 IS features an ISO 1600 setting that reduces the effects of camera shake and sharpens subjects in low-light situations, giving you greater shooting flexibility.
Red-eye Correction provides three options for removing red-eye from subjects in flash pictures. 1) The Red-eye Correction during shooting actually identifies and corrects red-eye in human subjects as pictures are taken. 2) The PowerShot SX120 IS can be set to automatically detect and correct red-eye during image playback.
