Light sensitivity is caused by a number of conditions that affect the eye (such as iritis, uveitis, and keratitis), as well as conditions that affect the entire body. Migraine headache is a common cause of photophobia, with a majority of migraine sufferers reporting sensitivity to light.
bNewQmatrix. Indicates which new inverse-quantization matrices are present in an inverse-quantization matrix buffer. Each element in this array corresponds to an inverse-quantization matrix type and indicates whether a new inverse-quantization matrix of that type is present in the buffer.he DXVA_QmatrixData structure is sent by the host decoder to the accelerator to load inverse-quantization matrix data for off-host bitstream compressed video picture decoding.
In mathematics, an inverse function (or anti-function[1]) is a function that reverses another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa. i.e., f(x) = y if and only if g(y) = x.[2][3]
