12Bit, 16Bit, 18Bit and 24Bit color information storage format of the phone?

            


Will 12Bit, 16Bit, 18Bit and 24Bit color phone store in memory in the way color information is what? - For example 16Bit color is not accounted for two Byte? Or it will occupy the whole of 32Bit, but only in front of 2Byte? - Brother did before the 18Bit BREW handset is occupied 32Bit, but only the front 18Bit effective, so many times I asked ......

If it is in memory, each representing the corresponding 1,2,4,8 bit, 12,16 2 bytes, 24 accounted for 4 byte, 18 do not know, maybe it is 4 bytes
