The term bit is a contraction of the more descriptive phrase binary digit.īytes are groups of 8-bits linked together for processing. It's basically a single element in the computer that like a light bulb has only two possible states, on (indicating 1) or off (indicating 0).
When reading about digital systems, you frequently encounter the terms bit and byte.
( Ed note: Are there any 30/36 bit monitors or printers?) Review: Bits and Bytes These extra bits are used to improve the color in the image as it is processed down to its 24-bit final form. Some cameras and scanners will use 30 or 36 bits per pixel. Color images are displayed using 4 bits (16 colors), 8 bits (256 colors), 16 bits (65 thousand colors) called high color, and 24 bits (16 million colors) called true color. Gray scale images need 8 bits to display 256 different shades of gray. Nameīlack and white images require only 2-bits to indicate which pixels are white and which are black. Here's a table to show you some other possibilities. For example, 8-bits gives you 256 colors because 28=256. To calculate how many different colors can be captured or displayed, simply raise the number 2 to the power of the number of bits used to record or display the image. How do bits and colors relate to one another? It's simple arithmetic. When the Control panel opens, double-click the Display icon or command to display the Display Properties dialog box, then click the Settings tab on the dialog box and check the Color palette setting.

To see if your Windows system supports True Color (not all do), display Window's Start menu, point to Settings to cascade the menu, and then click Control Panel. You may have to set your system to full-color, it doesn't happen automatically. It's called true color because these systems display 16 million colors, about the number the human eye can discern. However, almost all newer systems include a video card and a monitor that can display what's called 24-bit True Color. Older PCs are stuck with displays that show only 16 or 256 colors. How many colors there are in an image, or how many a system can display is referred to as color depth, pixel-depth, or bit depth. Digital images can approximate this color realism, but whether they do so on your system depends on its capabilities and its settings. When you view a natural scene, or a well done photographic color print, you are able to differentiate millions of colors. Equally important is the number of colors in the image. Resolution isn't the only factor governing the quality of your images. While DPI and PPI are used interchangeably, they refer to two different terms: PPI is an input image resolution, and DPI is a resolution of an output device, like a printer.The math of color dept 4 The Arithmetic of Color Depth DPI stands for dots per inch DPI is a measure of dot density within an image, in inches.PPCM stands for Pixels Per Centimeter PPCM is a measure of pixel density within an image, in centimeters (cm).PPI stands for Pixels Per Inch PPI is a measure of pixel density within an image, in inches.The PPI calculator assumes, that the horizontal and vertical pixel densities (of the target image) are the same, as the most imaging devices have square pixels. The calculation results include the image density in PPI (Pixels Per Inch) and PPCM (pixels per centimeter), the image total number of pixels, the image aspect ratio, the image number of pixels per unit of area, the image width and height in numerous units of length, and the image area in many units of area. The PPI calculator computes many attributes of an image using the entered image width and height in pixels, and the image width in any unit of length measurement.About this page: Pixels Per Inch (PPI) calculator.
