ND (Neutral Density) Filter
A filter available in different saturation levels that adjusts the brightness
without affecting the color tone of pictures.
Noise Reduction
Process to reduce noise (image roughness or unevenness) caused by
slow shutter speed or high sensitivity shooting.
NTSC/PAL
These are video output formats. NTSC is mainly used in Japan, North
America, and South Korea. PAL is mainly used in Europe and in China.
Quality Level
This refers to the image compression ratio. The lower the compression,
the more detailed the image. The image becomes rougher as the
compression rate rises.
RAW data
Unedited image data output from the CCD. RAW data are data before
being internally processed by the camera. Camera settings at the time of
capture, such as White Balance, Contrast, Saturation, and Sharpness can
be set for each frame after shooting. In addition, RAW data are 12 bit data
that contain 16 times the information of 8 bit JPEG data. Rich gradations
are possible. Transfer RAW data to your computer and use the provided
software to create image data with different settings, such as JPEG.
Recorded Pixels
Indicates the size of the image by the number of pixels. The more pixels
that compose a picture, the larger the image size.
Shutter Speed
The length of time that the shutter is open and light strikes the CCD. The
amount of light that strikes the CCD can be changed by altering the shutter
speed.
sRGB (standard RGB)
12
International standard of color space established by the IEC (International
Electrotechnical Commission). This is defined from color space for
computer monitors and is also used as the standard color space for Exif.
