![]() With the relatively low color depth, the stored value is typically a number representing the index into a color map or palette (a form of vector quantization). 8 and smaller use an adaptive palette so quality may be better than some systems can provide. Same image on five different color depths, showing resulting (compressed) file sizes.The number of bits of resolved intensity in a color channel is also known as radiometric resolution, especially in the context of satellite images. The definition of both color precision and gamut is accomplished with a color encoding specification which assigns a digital code value to a location in a color space. ![]() ![]() Modern standards tend to use bits per component, but historical lower-depth systems used bits per pixel more often.Ĭolor depth is only one aspect of color representation, expressing the precision with which the amount of each primary can be expressed the other aspect is how broad a range of colors can be expressed (the gamut). When referring to a color component, the concept can be defined as bits per component, bits per channel, bits per color (all three abbreviated bpc), and also bits per pixel component, bits per color channel or bits per sample (bps). When referring to a pixel, the concept can be defined as bits per pixel (bpp). Color depth or colour depth (see spelling differences), also known as bit depth, is either the number of bits used to indicate the color of a single pixel, or the number of bits used for each color component of a single pixel. ![]()
