Image Storage and Interface

The C-60 uses xD-Picture Cards for memory storage, and comes equipped with a 32MB card. Larger card capacities are available up to 512MB separately.

The C-60 can store images in both uncompressed TIFF and compressed JPEG file formats. JPEG compression levels include Super High Quality (SHQ), High Quality (HQ), and Standard Quality (SQ). No less than six resolutions are available, with a variety at the Standard Quality setting. Resolutions include 2,816 x 2,112, 2,560 x 1,920, 2,272 x 1,704, 2,048 x 1,536, 1,600 x 1,200, 1,280 x 960, 1,024 x 768, or 640 x 480 pixels.

The C-60's file naming protocol includes the month and day at the beginning of the file name, and provides the option of numbering images progressively from one card to the next, or of resetting the naming sequence for each card. The camera lets you write-protect individual images from accidental erasure through the Playback menu (though individually protected images can still be erased by a card format operation).

The table below summarizes the compression ratios and number of images which can be stored on the included 32MB xD-Picture Card with each size/quality combination.

The Olympus C-60 connects to a host computer via a USB interface. Downloading files to my Sony desktop running Windows XP (Pentium IV, 2.4 GHz), I clocked it at 501 KBytes/second. This is pretty good performance for a camera with a USB v1.1 interface, but slower than many current cameras with USB v2.0 connections routinely manage. (Cameras with slow USB interfaces run as low as 300 KB/s, cameras with fast v1.1 interfaces run as high as 600 KB/s. Cameras with USB v2.0 interfaces run as fast as several megabytes/second.)
