GE PJ1 User Manual (en)

The quality setting adjusts the compression ratio of the 
images. Higher quality settings will produce finer detailed 
photos, but will take up more memory space.
Three quality settings are available:
 Quality : Best
 Quality : Fine
Quality : Normal
The size settings refer to the image resolution in pixels. A 
higher image resolution allows you to print that image in 
larger sizes without degrading the image quality. 
The bigger the number of recorded pixels is, the better 
the image quality becomes. However, as the number 
of recorded pixels becomes smaller, you will be able to 
record more pictures on a memory card.
