Q.No.1721:	What determines the number of images that can be stored on the memory card. What is the compression ratio?
Ans :	The chart below shows the number of images that can be stored on 8MB and 16 MB cards, at the various image quality and size settings. If you are using a card larger that 16MB, calculated the possible number of images that can be stored by multiplying the figure for the 16MB card by the appropriate ratio. COOLPIIX995 Number of images that can be stored on 8 MB and 16MB memory cards. 8MB 16MB 64MB FULL (2048�~1536) HI 0 1 6 FINE 4 10 40 NORMAL 9 19 78 BASIC 18 37 151 UXGA (1600�~1200) FINE 8 16 65 NORMAL 15 31 126 BASIC 29 59 236 SXGA (1280�~960) FINE 12 24 100 NORMAL 23 47 190 BASIC 43 86 347 XGA (1024�~768) FINE 18 37 151 NORMAL 34 69 278 BASIC 60 121 488 VGA (640�~480) FINE 43 86 347 NORMAL 71 144 578 BASIC 114 229 918 3�F2 (2048�~1360) HI 0 1 7 FINE 5 11 45 NORMAL 11 22 88 BASIC 21 42 169
*	Due to the characteristics of J-PEG compression, the number of images that can be stored may vary slightly. As such, the above figures should be considered approximate. The four compression ratios of FINE, NORMAL and BASIC correspond to a compression of around 1/4, 1/8, and 1/16 respectively. Ultra HS images are always recorded under Normal compression at a size of 320 x 240 pixels. (No other setting can be chosen.) Since this image size is 1/4 the size of a VGA image, the memory requirements for Ultra HS images are four times smaller than those for VGA images recorded at Normal. In other words, the number of Ultra HS images that can be stored on the memory card is four times greater than the number of VGA images that can be recorded at Normal.
