NOTE: You can also select the file format when saving an image from the REC menu.
The following table gives the resulting file sizes for various image file settings. Since actual file sizes of JPEG images can vary widely from image to image, the JPEG values given here are intended to serve only as a guide.

Separate R, G, and B channel data is stored. Overlay composites can be created by incorporating colored drawings with a pen or other tool.
When you save overlays with the TOOL menu, keep in mind that it may be difficult to read text information if the file is too small or features high JPEG compression.
We recommend saving files that include text information in BMP format at 1280*960 resolution or higher.
Source Setting Guidelines (Photography mode)The source setting represents the CCD mode during image acquisition when you freeze, save, or print images. The
In certain cases, you should avoid switching CCD modes – for example, when you expect to freeze images repeatedly. To keep the
The CCD mode will not switch if you view images saved at the lowest resolution (640*480 for 5M cameras or 400*300 for 2M cameras).
On the other hand, the CCD mode will switch automatically if the display mode is set to "C.Scan."
If the quality of saved images is important, choose the highest resolution for the source setting ("s5M" for 5M cameras or "s2M" for 2M cameras).
