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 colour 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".
