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.
The dequantized coefficients are inverse transformed to determine a decoded residue. Les coefficients dÃ©quantifiÃ©s sont traitÃ©s par transformÃ©e inverse en vue de la dÃ©termination d'un rÃ©sidu dÃ©codÃ©. A sample residue may not always be available. Il se peut, dans certains cas, qu'il ne reste pas de rÃ©sidu d'Ã©chantillon.
