From 247ec0cb841c28b97a186675c0ef923a0ede2f40 Mon Sep 17 00:00:00 2001 From: Niklas Haas Date: Sun, 26 Jun 2016 19:57:29 +0200 Subject: csputils: add Panasonic V-Gamut primaries This is actually not entirely trivial since it involves negative Yxy coordinates, so the CMM has to be capable of full floating point operation. Fortunately, LittleCMS is, so we can just blindly implement it. --- video/csputils.c | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'video/csputils.c') diff --git a/video/csputils.c b/video/csputils.c index e9e6772ac8..b85b1f28f2 100644 --- a/video/csputils.c +++ b/video/csputils.c @@ -65,6 +65,7 @@ const struct m_opt_choice_alternatives mp_csp_prim_names[] = { {"prophoto", MP_CSP_PRIM_PRO_PHOTO}, {"cie1931", MP_CSP_PRIM_CIE_1931}, {"dci-p3", MP_CSP_PRIM_DCI_P3}, + {"v-gamut", MP_CSP_PRIM_V_GAMUT}, {0} }; @@ -422,6 +423,14 @@ struct mp_csp_primaries mp_get_csp_primaries(enum mp_csp_prim spc) .blue = {0.150, 0.060}, .white = d65 }; + // From Panasonic VARICAM reference manual + case MP_CSP_PRIM_V_GAMUT: + return (struct mp_csp_primaries) { + .red = {0.730, 0.280}, + .green = {0.165, 0.840}, + .blue = {0.100, -0.03}, + .white = d65 + }; default: return (struct mp_csp_primaries) {{0}}; } -- cgit v1.2.3
