Dequantize data block
|FwStatus||fwiQuantInv8x8_JPEG_16s_C1I||(||Fw16s * pSrcDst, const Fw16u * pQuantInvTable );|
|pQuantInvTable||Pointer to the inverse quantization table (decoder).|
|pSrcDst||Pointer to a location in a buffer that contains both the source and destination.|
This function reads a block of uncompressed image data, dequantizes the values, and writes an 8X8 data block of DCT coefficients to the same location.
Dequantization is performed using the following formula.
s[vu] = (sq[vu]*Q[vu])
Because quantization is lossy, some of the data may be saturated and require up-sampling.
