Next, convert each component to a 5 or 6-bit value, depending on whether.Each component is an integer between 0 and 255. First, extract the red, green, and blue components of the 24-bit RGB888Ĭolor value.How can I convert 24-bit RGB (RGB888) to 16-bit RGB (RGB565)? If you need to use transparency, you have to use a different colorįormat that has an alpha channel, such as standard RGBA or No, transparency is not supported in RGB565 since it does not have an alphaĬhannel. Can I use transparency with RGB565 colors? Represent more variations in the green color, which results in a moreĪccurate representation of images. By allocating more bits to the green channel, RGB565 can This isĭue to the way the cones in the human eye that detect color are distributed: there are more cones that are sensitive to green light than to red orīlue light. To variations in the green channel than in the red or blue channels. Uses this extra bit for the green channel (for a total of 6 bits) and 5 bitsĮach for the red and blue channels because the human eye is more sensitive Splitting 16 bits into 3 parts leaves one extra bit for one channel. Why does RGB565 use 6 bits for the green channel but 5 for red and blue? Reduced image quality, especially in images with smooth gradients or subtleĬolor differences. RGB888: RGB565 supports a maximum of 65,536 colors, compared to the 16.7 The main disadvantage of RGB565 is that it has a lower color depth than Power when rendering and displaying images, as they need to process fewer Devices using the RGB565 color format may consume less Performance in real-time applications, such as video games or image Process as there is less data to read and write. RGB565 images can be stored in less memory (33% less to be precise), whichĬan be beneficial in memory-constrained environments like embedded systemsĪ consequence of using less memory is that RGB565 data can be faster to Would use 320 x 240 x 2 = 153,600 bytes of memory, whereas the same image in For example, a 320 x 240 pixel image in RGB565 The main advantage of RGB565 is that it uses less memory than other RGBĬolor formats like RGB888. What are the advantages and disadvantages of the RGB565 color format? Which uses 24 bits per pixel and can represent 256 x 256 x 256 = 16,777,216ĭifferent colors. Number of colors that can be represented with other formats like RGB888, This allows for 32 x 64 x 32 = 65,536ĭifferent colors to be represented, which is considerably less than the Green (2^6 = 64), and the 5 bits for the blue channel can represent 32ĭifferent shades of blue (2^5 = 32). = 32), the 6 bits for the green channel can represent 64 different shades of The 5 bits for the red channel can represent 32 different shades of red (2^5 This format is characterizedīy a smaller color depth than other formats like RGB888, but it is more Range of colors with a limited number of bits. ![]() It is used in many displayĭevices, such as LCD screens and computer monitors, to represent a wide Represent a color, with 5 bits for the red channel, 6 bits for the greenĬhannel, and 5 bits for the blue channel. RGB565 (also known as 16-bit RGB) is a color format that uses 16 bits to If you're not fully satisfied, please contact us and we'll make sure to help.See also: our RGB565 Color Codes Table.
