Horizontal size of the image in pixels.
Vertical size of the image in pixels.
Horizontal resolution.
- On a free air camera system such as number plate or face capturing this value is related to a PAL or NTSC image in percentage.
For example:
- in case of PAL image 768 pixel = 100 %, 384 pixel = 50 %
- in case of NTSC image 640 pixel = 100 %, 320 pixel = 50 %
- On a fixed object windowed camera system like document capturing this value is definied in pixel-per-meter (for example 300 DPI = 11811 pix/m).
- (0 value = not defined)
