(15) Low Reference Number Register(low_ref_no)
High : (Address 57h default:00h, Read Only)
Low : (Address 58h, default:00h, Read Only)
Low Reference Number Registers indicates number of pixels in frame that have a value less then 5. A
reference level values of each pixel is compare with ‘5’, and accumulated to these registers during read state.
This counter value called
low_ref_no
, consist of two bytes and it is read only registers. Real number of pixels
that have value less than 5 is the twice of these register value. If
low_ref_no
is big value, you must increase
data value of Reset Level Control Register. These registers are updated after every VSYNC signal.
(16) High Reference Number Register (high_ref_no)
High : (Address 59h, default:00h, Read Only)
Low : (Address 5Ah, default:00h, Read Only)
High Reference Number Registers indicates number of pixels in a frame that have a value great then 123.
Reference level values of each pixels is compared with ‘123’, and accumulated to these registers during read
state. This counter value called
high_ref_no
, consist of two bytes and it is read only registers. Real number of
pixels that have value great than 123 is the twice of these register value. If
high_ref_no
is big value, you must
decrease data value of Reset Level Control Register. These registers are also updated after every VSYNC
signal.
