(1)
Frame Rate [fps] - rate of output image frames. Defined in units of frames per second.
(2)
Exposure Time [µsec] - time in microseconds (µsec) in which sensor is exposed to light. This time
is subject to the specified image frame rate:
𝑒𝑥𝑝𝑜𝑠𝑢𝑟𝑒 =
1,000,000
𝑓𝑟𝑎𝑚𝑒 𝑟𝑎𝑡𝑒
Additional delays might be taken to consideration in calculation of maximum exposure, like delay
between frames, etc.

General purpose LUT per color
The ISP will be per single fiber channel and will accept 4 pixels in parallel. Each ISP should have its
CSR and be as a closed unit with Avalon interfaces.

Pixel Correction Control
The defected pixel correction will correct up to 32 pixels in the sensor and up to 2 running pixels.
The pixel correction coordinates represent pixels of sensor’s visible ROI, therefore identifying the
correct X and Y coordinate should be done using default, full resolution image.
