What is a color depth?
Color depth is a link to how many colors the computer screen can display, based on the number of bits per pixel. For example, the color depth of eight bits provides 256 colors. The color depth increases exponentially as bits are added, allowing people to see more precisely colored and more detailed pictures. Many computers allow people to choose between several color depths for the color display. Along with other graphic properties, such as resolution, this will affect the final display appearance of images on the screen.
One bit per pixel offers two colors. Pixel can be on or off to create one or two colors. Black and white are common, although some computers that once worked with black and green. Adding another bit creates the possibility of four colors, as each bit can be turned on and off to create multiple layers of color. Once the bits are added, more colors are possible via eight-, 16- and 24-bit colors. Twenty four -bit colors, bringing 16,777 216 colors, sometimes NazIt "True color," reference to the accuracy of affordable shading and shade.
with high color depth values can be completely different and detailed. Computers can use a range of color display systems, including red, green, blue (RBG) of the system where colors are expressed in red, green and blue. Korya, purple, yellow and key or black (CMYK) Color display is also available on some computers and graphic designers can be used to prepare images for printing, as print operators usually use CMYK color coding to mix colors for print runs. Hexadecimal identification can also be used.
High color depth is not always necessary. For something like text processing, only two colors are absolutely necessary, while other colors can be useful to relax eye tension and offer functions such as using highlighting, different text colors, etc.Image processing, Other Hand, requires a high color depth when people work with things like color photos.
It is important to note that the color depth is controlled by the screen setting, not the image itself. The person can save an image in 24 -bit color and send it to a person with an eight -bit monitor and the other person will see only 256 colors, no matter how many colors are in the original picture. The image quality can also be influenced by other factors involved in the image storage and processing process. For things like preparing images for display on the web, people must consider quality problems to make sure the images are displayed as best in all possible browsers. Extremely fine color variations may not be visible in all browsers, leading to a reduction in understanding and pleasure by site users.
