10 Renesas R-Car VSP1 1-D Histogram Data
16 This format describes histogram data generated by the Renesas R-Car VSP1 1-D
20 or HSV data. It operates on a possibly cropped and subsampled input image and
21 computes the minimum, maximum and sum of all pixels as well as per-channel
25 three channels (RGB data only) or on the Y channel only (YCbCr only). It can
29 - In *64 bins normal mode*, the HGO operates on the three channels independently
30 to compute three 64-bins histograms. RGB, YCbCr and HSV image formats are
32 - In *64 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
33 channels to compute a single 64-bins histogram. Only the RGB image format is
35 - In *256 bins normal mode*, the HGO operates on the Y channel to compute a
36 single 256-bins histogram. Only the YCbCr image format is supported.
37 - In *256 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
38 channels to compute a single 256-bins histogram. Only the RGB image format is
