Only one red, green or blue -value is given for each pixel. Missing components must be interpolated -from neighbouring pixels. From left to right the first row consists of a -red and green value, the second row of a green and blue value. This -scheme repeats to the right and down for every two columns and rows. +These four pixel formats are raw sRGB / Bayer formats with 8 bits per +sample. Each sample is stored in a byte. Each n-pixel row contains n/2 +green samples and n/2 blue or red samples, with alternating red and +blue rows. They are conventionally described as GRGR... BGBG..., +RGRG... GBGB..., etc. Below is an example of one of these formats: **Byte Order.** Each cell is one byte. @@ -35,11 +37,11 @@ Each cell is one byte. - start + 0: - - R\ :sub:`00` + - B\ :sub:`00` - G\ :sub:`01` - - R\ :sub:`02` + - B\ :sub:`02` - G\ :sub:`03` @@ -49,21 +51,21 @@ Each cell is one byte. - G\ :sub:`10` - - B\ :sub:`11` + - R\ :sub:`11` - G\ :sub:`12` - - B\ :sub:`13` + - R\ :sub:`13` - .. row 3 - start + 8: - - R\ :sub:`20` + - B\ :sub:`20` - G\ :sub:`21` - - R\ :sub:`22` + - B\ :sub:`22` - G\ :sub:`23` @@ -73,8 +75,8 @@ Each cell is one byte. - G\ :sub:`30` - - B\ :sub:`31` + - R\ :sub:`31` - G\ :sub:`32` - - B\ :sub:`33` + - R\ :sub:`33` |
