- What is the difference between optical zoom and other different types of zoom?
- A67
- The camera is equipped with various types of zoom: optical zoom, HD Zoom, Single SR Zoom, and digital zoom.
• Optical Zoom : Changes the lens focal distance. • HD Zoom : Allows greater zoom capabilities by cutting out a portion of the original image and enlarging it. • Single SR Zoom : Super-resolution zoom expands the zoom ratio in a way that minimizes image deterioration. • Digital Zoom : Digitally processes the center of the image to enlarge it.
Your camera provides you with 4X optical zoom (6X when combined with super-resolution zoom), which can be used in combination with digital zoom for total zoom capabilities of 63.8X(VGA size).
To enable Single SR Zoom , select the Control Panel "MENU" item and then select "On" for the "Single SR Zoom" setting.
Optical zoom, HD Zoom, and digital zoom can be used regardless of whether Single SR Zoom is on or off.
NOTE
• Digital zoom is divided between two zones: a zone in which there is no coarsening of the image and a zone in which digital zoom causes coarsening of the image. The zoom operation will pause at the point where zoom crosses over from the HD Zoom zone and enters the zone in which coarsening of the image occurs. Remember that zooming past this point will cause deterioration of image quality. • Except for optical zoom, all other types of zoom are disabled while "Date" or "Date & Time" is selected for the "Time Stamp" setting.
