4.2.5.1.5 Define the Image Pixel Bit Depth
A variety of the Phantom camera sensors have the ability to record and save 8-, 10-, 12-, or 14-bit
values, (gray scale level images), that are transferred to the computer as either 16-bit or 8-bit words.
By default these Phantom cameras display 8-bit, (256 gray scale level), images. The 8-bits used to
display these images are the most significant, or high order, bits of 14-bit values.
NOTE
Both 8-bit to 14-bit images need exactly the same amount of light to saturate the sensor. What
differs is the fineness in the number of levels recorded.
1.
Click the Live Control Panel Tab.
2.
Click on Camera Settings.
3.
Click the down-arrow to the right of the Bit Depth entry window, then
4.
Select the desired image pixel Bit Depth to record image data, (images stored in the camera
DRAM), and save image data, (images to be transferred from the cameras DRAM into the
Phantom Control Unit computer).
RESULT: The image data being recorded and saved will be at the image pixel bit depth selected.
