- Pixel -
The µVision board internally handles image data as a
group of individual points, one of which is called pixel.
The µVision board handles 512 x 480 pixels (lengthwise x
widthwise) in the storage memory (processing screen),
and 624 x 480 pixels (lengthwise x widthwise) in the
dedicated drawing memory (drawing screen).
- Brightness -
Each pixel of image data processed by
the µVision board has a value (0 to 255)
that represents brightness (in 256
steps). This value is called brightness.
As the number gets close to “0”, the
pixel becomes darker. As it gets closer
to 255, the pixel becomes brighter.
