color_correction_matrix — GFX2D isp op

使い方

Apply a 3x3 colour-correction matrix: out = rgb @ ccm.T per pixel, clipped to [0, 1].

The CCM maps the sensor’s spectral response onto the display primaries. With normalize_rows (default) every row is divided by its sum so that white stays white ([1, 1, 1] -> [1, 1, 1]) — the constraint most calibration procedures impose; pass False to apply the matrix as given.

Ground truth: the identity matrix is the exact identity; a normalised matrix maps every grey [v, v, v] to itself to 1e-15. Raises ValueError: ccm is not a finite 3x3, or a row sums to 0 when normalising.
