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 operation is an operation that undoes what was done by the previous operation. The four main mathematical operations are addition, subtraction, multiplication, division. The inverse of addition is subtraction and vice versa. The inverse of multiplication is division and vice versa.
