SHUT_HI
Shutter Open Time (Upper 8-bits) Register
Access: Read
SHUT_LO
Shutter Open Time (Lower 8-bits) Register
Access: Read
Data Type: Sixteen bit unsigned integer.
USAGE: Units are in clock cycles. Read SHUT_HI first, then SHUT_LO. They should be read consecutively. The shutter is
PIX_MAX
Maximum Pixel Value Register
Access: Read
Data Type: Eight-bit number.
USAGE: Store the highest pixel value in current frame. Minimum value = 0, maximum value = 254. The highest pixel
PIX_ACCUM
Average Pixel Value Register
Access: Read
Data Type: High 8-bits of an unsigned 17-bit integer.
USAGE: This register stores the accumulated pixel value of the last image taken. This register can be used to find the

adjusted to keep the average and maximum pixel values within normal operating ranges. The shutter value is
automatically adjusted.
value may vary with different frame.
average pixel value, where Average Pixel = (register value AP[7:0])* 1.058
The maximum accumulated value is 122936 but only bits [16:9] are reported, therefore the maximum register
value is 240. The minimum is 0. The PIX_ACCUM value may vary with different frame.
