Select the Recording Bit Length
Select the Recording Bit Length
The number of bits per recorded image pixel can be changed. As the number of bits increase, the gradient
(amount of change in the brightness) of the image gets finer, so the gradient representation is one of high
image quality. As the number of bits decrease, the gradient of the image gets coarser which saves recording
memory and extends the amount of recording time available.
