10. Image Resolution   
Resolution is the size of a digital image measured in pixels (dots), expressed as horizontal 
number of pixels x vertical number of pixels.  The VQ350 offers two resolution modes.  The 
highest (best) resolution is 640 x 480.  This is called VGA resolution.  The second choice of 
resolution is 320 x 240.    This is called QVGA resolution. 
 
VGA resolution images will be the best possible images from VQ350. QVGA resolution images 
are noticeably smaller when you view them on your computer.  QVGA resolution is not 
recommended for individual digital images.    The primary advantage to QVGA resolution is that 
you may store more images (four times more) than VGA resolution. 
 
If you would like to get into the QVGA resolution, turn on VQ350.    Press the Mode Button until 
“    ” appears on the LCD display and “Hi” starts flashing “on” and “off.”  Press the Shutter 
Button to change “Hi” to “LO.” (QVGA mode) 
 
To change the resolution from QVGA to VGA, press the Mode Button until “     “ appears on 
the LCD display and “LO”  begins flashing “on” and “off.”  Press the Shutter  Button  to 
change “LO” to “Hi”----which is the VGA mode.   
 
11. High/Low Image Compression: Image Quality and Memory 
Press the Mode Button until HD/LD appears on the LCD display.    Press the Shutter Button 
to set the picture to “ HD ” (highest image quality, using the least compression) or “ LD ”(lower 
image quality, using more compression).  Higher quality images captured in the HD Mode will 
use more of your camera’s available memory (storage space).  The LD Mode allows you to 
store more images, but of a lesser quality. 

12. Light Frequency   
When capturing images or movie clips under indoor lighting, the image quality will be best if you 
set VQ350 to match the frequency of the room-lighting.  In general 60 Hz frequency is used in
