4bpc
4bpc is a term that can refer to several different concepts, depending on the context. One common usage is in digital color representation, where it stands for 4 bits per channel. In this context, each color channel (such as red, green, and blue) is allocated 4 bits of data. This allows for 2^4, or 16, distinct shades for each channel. Consequently, a display or image using 4 bits per channel color would have a limited color depth, resulting in a palette of 16 x 16 x 16 = 4096 possible colors. This is significantly less than the 24 bits per channel (8 bits per channel) commonly found in modern displays and image formats, which allows for millions of colors. Lower bit depths like 4bpc can be used in situations where bandwidth or storage is severely limited, or for specific artistic effects.
In other contexts, "4bpc" might be an acronym or abbreviation specific to a particular company, project, or
