Steve et al., Given recent interest in competing technologies, the following (incomplete) table lists digital cameras by the type of memory expansion that they use together with the image size in pixels. No Memory Expansion Camera Image Size No. Photos Agfa ePhoto 307 640x480 36 Casio QV-11 320x240 96 Casio QV-100 640x480 64 Casio QV-300 640x480 64 Epson PhotoPC 500 640x480 30 Kodak DC20 493x373 8 Nikon Coolpix 100 512x480 21 Nikon Coolpix 300 640x480 66 Olympus C-400L 640x480 20 Olympus C-410L 640x480 30 Polaroid PDC2000-40 1600x1200 40 Praktica PD-100 320x240 64 Ricoh RDC-300 640x480 ??

Notable exceptions are the Nikon and Toshiba cameras which plug directly into a pcmcia port enabling rapid data transfer from the camera to the computer. The number of photos is the number of photographs at the highest resolution that can be stored in the camera before they have to be transfered or deleted - this is a manufacturer's estimate. Floppy Disc is a standard 1.44MB disc. SmartMedia (SSFDC) - currently available in 2MB and 4MB sizes with 8MB and 64MB cards eventually available. The cards can be either 3.3V or 5V - the wrong voltage card will not work so need to know which voltage card for which camera. The smartmedia memory can be converted to a standard pcmcia Type II ATA flashram form via an adapter. CompactFlash (CF) - Available in sizes up to 20MB now. TypeII - This refers to a mechanical size but is usually synonymous with the ATA interface (de facto standard) when used to describe pcmcia flash memory - the camera vendors were not too specific with their descriptions. Sizes available up to at least 85MB and rumoured availability of 100MB+ cards in near future. TypeIII - These are generally miniature rotating hardrives. The maximum drive size is currently 340MB although a 510MB drive is rumoured. Power consumption is an issue for portable devices. Memory pricing: Of the flash technologies, for a given size SSFDC is cheaper than CF which is marginally cheaper than TypeII ATA. The Type III hard drives are much cheaper than the flashram. Gary
