For 16-bit pixels, they use pixel masks which change based on whether the 16-bit pixel format is 565 or 555. The constants colorMask, lowPixelMask, qColorMask, qLowPixelMask, redBlueMask, and greenMask are 16-bit masks. The lower 8 bits are identical in either pixel format. Two interpolation functions are described:
In some systems, as Hercules and CGA graphic cards for the IBM PC, a bit value of 1 represents white pixels (light on) and a value of 0 the black ones (light off); others, like the Atari ST and Apple Macintosh with monochrome monitors, a bit value of 0 means a white pixel (no ink) and a value of 1 means a black pixel (dot of ink), which it ...
The 4-bit per pixel (4bpp) format supports 16 distinct colors and stores 2 pixels per 1 byte, the left-most pixel being in the more significant nibble. [5] Each pixel value is a 4-bit index into a table of up to 16 colors. The 8-bit per pixel (8bpp) format supports 256 distinct colors and stores 1 pixel per 1 byte.
A 2-bit indexed color image. The color of each pixel is represented by a number; each number (the index) corresponds to a color in the color table (the palette).. In computing, indexed color is a technique to manage digital images' colors in a limited fashion, in order to save computer memory and file storage, while speeding up display refresh and file transfers.
An entire class of operations [clarification needed] on binary images operates on a 3×3 window of the image. This contains nine pixels, so 2 9 or 512 possible values. . Considering only the central pixel, it is possible to define whether it remains set or unset, based on the surroundi
The pixel format of the image sensor dictates or determines the color depth (often referred to as bit depth), color filter array filtering patterns that are used by the sensor, and the method by which pixel information is stored (packed pixel and planar pixel). The pixel format for the sensor is typically user-configurable. [1] [2]
The IEEE 754 standard [9] specifies a binary16 as having the following format: Sign bit: 1 bit; Exponent width: 5 bits; Significand precision: 11 bits (10 explicitly stored) The format is laid out as follows: The format is assumed to have an implicit lead bit with value 1 unless the exponent field is stored with all zeros.
Color depth, 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. When referring to a pixel, the concept can be defined as bits per pixel (bpp).
