Notes
When you set [TV TYPE] to [4:3], the image quality may deteriorate. Also, when the recorded image's

aspect ratio switches between 16:9 (wide) and 4:3, the image may jitter.
On some 4:3 TVs, the photos recorded in 4:3 aspect ratio may not be displayed full screen. This is not a

malfunction.
When you play back an image recorded in 16:9 (wide) aspect ratio on a 4:3 TV not compatible with the

16:9 (wide) signal, set [TV TYPE] to [4:3].
