① Compression rate
The file size of JPEG-compressed image depends upon the actual content of the image. Images
containing much detail will generate larger files. Image quality is controlled through the level of
compression; where, high compression yields small files, while low compression maintains higher
image quality at the expense of larger files. The table below contains compression ratios for each step,
derived from real-life tests:
Compression Rate Level 1 Level 2 Level 3 Level 4 Level 5
QVGA 15 18 21 24 27
VGA 15 20 25 30 35
Level 6 Level 7 Level 8 Level 9 Level 10
30 33 36 39 42
40 45 50 55 60
② Image size
You may choose the image size VGA(640x480) or QVGA(320x240)
Large sizes of image (VGA) yields lower frame rate, while small size maintains higher frame rate
③ Vertical Flip
To turn the image view upside down
④ Horizontal Flip
To switch the image view right from left
