Relationship between pixels and memory

One 、 The formula

Memory occupied by pixels = The resolution of the x Pixel depth

Two 、 give an example ：

1） The resolution of a color image is 1024x768, Every pixel uses R,G,B Three components represent , If each component uses 8 position , So one pixel shares 24 Who said , Let's say the depth of the pixel is 24. So the memory occupied by this picture is ：1024x768x3 byte.

2） One OLCD The pixels of the display screen are 128x64, Pixel depth is 1bit, The data needed for a complete screen is 128x64x1 bit.
