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 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 image sensor. RAW data is 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
is 12 bit data that contains 16 times the information of 8 bit JPEG and TIFF
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 or TIFF.
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 image
sensor. The amount of light that strikes the image sensor can be changed
by altering the shutter speed.
