Image Storage and Interface
The
PDR-M700 stores images on SD memory cards, and comes with a 16-megabyte card.
I highly recommend picking up a larger capacity card right away, at least a
64-megabyte card, so you don't miss any shots. While data on SD memory cards
can be protected using the built-in write protection tab to lock the card, the
PDR-M700 also lets you protect individual images from accidental erasure (except
from card formatting) through an option in the Playback menu in Playback mode.
Protected images are denoted by a key symbol beneath the image. Protection can
be removed through the same process.
The PDR-M700's available resolutions are 2,048 x 1,536; 1,600 x 1,200; 1,280 x 960; 1,024 x 768; and 640 x 480. Three JPEG compression levels are available Fine (three stars), Normal (two stars), and Economy (one star). A Playback menu option lets you save images at lower resolutions, either at 320 x 240 or 160 x 120 pixels.
The table below shows the number of still images that can be stored on the included 16-megabyte card in various size/quality modes, and their approximate compression ratios:
| Resolution/Quality 32MB Memory Card | | | | |
| Full Resolution 2,048 x 1,536 | Images (Avg size) | 12 1.3 MB | 19 842 K | 421 K |
| Approx. Compression | 7:1 | 11:1 | | |
| 1,600 x 1,200 | Images (Avg size) | 15 1.0 MB | 23 674 K | 337 K |
| Approx. Compression | 6:1 | 9:1 | | |
| 1,280 x 960 | Images (Avg size) | 610 K | 405 K | 203 K |
| Approx. Compression | | | | |
| | Images (Avg size) | 405 K | 270 K | 135 K |
| Approx. Compression | | | | |
| | Images (Avg size) | 203 K | 135 K | 67 K |
| Approx. Compression | | | | |
The PDR-M700 connects to a host computer via a built-in USB port. In my tests,
the PDR-M700 transferred 6.43 megabytes of files in only 8.64 seconds, a transfer
rate of nearly 744 Kbytes/second. (This to a Sony VAIO running Windows XP on
a 2.4 GHz Pentium IV with 512 MB of RAM.) This is quite fast, suggesting that
the M700 actually has a USB 2.0 interface.
