TRANSFER DATA
Full image data can be captured and transferred in two different formats.
Picture Data Format
● JPEG ( 9
. jpg)
• This is the default setting. If you do not set Picture Format, image data is captured in this
format.
• JPEG (Joint Photographic Expert Group) is a leading standard defining the compression and
decompression of still color pictures.
• The quantity of transferred data appears smaller because the images are compressed. This
results in a shorter transfer time.
● Bitmap ( 9
. bmp)
• Transfer time is longer when you use this format because there is no data compression. The
benefit is that picture quality is maintained with no deterioration.
• Bitmap is a data format representing characters and graphics with combinations of pixels.
Full image data resolution is 768 x 552 pixels with 16.77 million colours (24-bit colour).
Index image data resolution is 80 x 60 pixels with 16.77 million colours (24-bit colour).
Capture Mode
● Frame Picture
• This is the default setting. If you do not set Picture Format, images are captured in this
mode.
• Since a frame consists of two overlapping 1/50 sec. images (one 1/25 sec. image forms a
field), it is unstable when capturing fast-moving motion pictures.
● Field Picture
• While a field contains only half the data of a frame — meaning that vertical resolution is
half that of a frame — images captured from a fast-moving motion picture are more stable
than when captured with "Frame Picture".
