ISO Sensitivity
The level of sensitivity to light. With a high sensitivity, images can be shot
with a high shutter speed even in dark places, reducing camera shake.
However, images taken with a high sensitivity are more susceptible to
noise.
JPEG
An image compression format. Although the image quality deteriorates a
little, images can be compressed to a smaller file size than with TIFF and
other formats. In this camera, select from Z (Premium), C (Best),
D (Better), or E (Good). Images recorded in JPEG format are suited for
viewing on your computer or attaching to e-mail.
Mired
Proportional scale of measurement that consistently shows color change
per unit. Determined by multiplying the inverse of the color temperature by
1,000,000.
ND (Neutral Density) Filter
A filter with many 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 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.
