| | Pixel - Wikipedia, the free encyclopedia |
 | | In computer programming, an image composed of pixels is known as a bitmapped image or a raster image. | | | Since the resolution of most computer displays can be adjusted from the computer's operating system, a display's pixel resolution may not be an absolute measurement. | | | Images composed of 256 colours or fewer are usually stored in the computer's video memory in chunky or planar format, where a pixel in memory is an index into a list of colours called a palette. |

| | Color depth - Wikipedia, the free encyclopedia |
| | Color depth is a computer graphics term describing the number of bits used to represent the color of a single pixel in a bitmapped image or video frame buffer. | | | The reason for using empty space is that all but the newest modern computers process data internally in units of 32 bits; as such, using this amount for each pixel can allow optimizations. | | | In graphics intensive applications such as computer games, a tradeoff of performance and quality can be achieved by raising or lowering the color depth of the display; graphics with lower color depths do not require as much frame buffer memory or display bandwidth, allowing them to be generated and displayed more quickly. |

| | Bit Depth Questionnaire |
| | Bit depth refers to how much color data a digital file can record for a single pixel. | | | Extended bit depth is also used for CMYK because each color channel of a true-color image needs to contain a full 256 levels of gray. | | | Just to make the discussion of bit depth a bit more confusing, extended bit depth can be used for other purposes, such as extra channels of data that can be used to store masks or texture maps. |

| | Lossless Compression |
| | Prediction of a pixel as the value of the adjacent left pixel resulted in a rate of 5.31 bits per pixel for the error, a compression of 33%. | | | Using optimal entropy encoding, it was found that the average coding rate for a 1:2 subsampling pyramid encoder operating on the test images was 6.76 bits per pixel of the original image. | | | Another way to exploit this correlation is to predict the pixel value based on its neighbours, and then to code only the error. |

| | Bits Per Pixel |
| | Bits per pixel is a form of mesurement that shows the number of possible colours that each pixel can use in an image. | | | This allows up to 256 different levels of red, green and blue, and an extra alpha channel that can be used to store transparency levels. | | | Nowadays, a typical RGB image contains no fewer than 256 luminosity values per color channel, which means a whole lot of bits. |

| | In true color virtual buffers, each pixel occupies either three bytes (24 bits per pixel) or four bytes (32 bits per pixel) of memory, making it possible to use 16.7 million different colors concurrently. | | | The 24-bit format is often designated 24bpp (bits per pixel), while the 32-bit format is designated 32bpp. | | | This means each pixel begins on a four-byte boundary and generally results in faster pixel access. |
