### How many color are possible if 24 bits pixel is used?

You are actually asking how many colors are possible in 8 bit per channel. 8 bit per channel means 256 colors, 1 bit= 2 colors, 2 bits= 4 colors, 3 bits= 8 colors, 4 bits= 16... 8bits= 256 colors. Since we have 3 channels in RGB color mode: Red, Green and Blue that means that we have 3x8= 24 bits per pixel in an image. 3x8 also means 256x256x256 colors possible. Number of possible colors… Read More

### How many bits per pixel are needed to represent a black and white image?

A "black and white" image is generally actually a grayscale image, which is typically represented with 8 bits per pixel. However, you can make images that use only one bit per pixel, making each pixel either fully black or fully white. The images created by the early graphics software MacPaint used only one bit per pixel.

### What is meant by an indexed image?

Typical uncompressed colored images use 24 or 32-bits per pixel of an image (RGB 8-bits per color). After some basic math of lets say an 8 Megapixel image quickly becomes a very large file on a computer. A type of compression used is to select some colors (typically called a palette) and for every pixel in the original image select a color in the palette that is closest to it (some other techniques exist to… Read More

Most modern digital cameras use 24 bits (8 bits per primary) to represent a color. But more or less can be used, depending on the quality desired. Many early computer graphics cards used only 4 bits to represent a color.

### How many Bits use in Bitmap?

1024bits If "Bitmap" refers to a specific entity, image or file: I do not know. But if "Bitmap" refers to a general image then it is 8 bytes or 64 bits per pixel. I just made 3 1*1 bitmap images at colordepths 2bits (monochrome), 8 bits (256 colors) and 24 bits (16 Million colors). The sizes of these images were the same! (surprized me too!) Then I made a 1*2 pixel image and it was… Read More

### How may bits are needed to represent the decimal number 200?

log2 200 = ln 200 ÷ ln 2 = 7.6... → need 8 bits. If a signed number is being stored, then 9 bits would be needed as one would be needed to indicate the sign of the number.

18 in binary is 10010 Since 18 can't be written in term of 2 to the power x, the number of bits needed is 5. The answer is 5

### How many bits for each pixel in true color format?

24 bits/pixel: one byte for red, one byte for green, one byte for blue.

### How many bits would be needed to represent a 64 character?

If you mean "64 different characters", you need log2(64) = 6 different bits.

### How many pixel 30 KB?

That depends on how many bits per pixel and how much the image is compressed. For example, a black-and-white (grayscale) image typically has 8 bits per pixel, but a full-color image may have 24 or 32 bits per pixel. JPEG compression may reduce the file size dramatically, sometimes by a factor of 50 or more.

### How many bits are needed to represent decimal value ranging from 0 to 12500?

The answer depends on the precision required for the numbers.

### How many shades can represent 8 bits per pixel?

If you consider that there are two possibilities for each byte, then taking two to the eighth power gives you 256 different possibilities. If you mean there are a total of 24-bits, then you can take 2 to the 24th power to get the answer, or you can take 256 to the 3rd power. Either way, that should represent about 16.7 million possibilities.

### How long would it take to load a 640 by -480 frame buffer with 12 bits per pixel if 105 bits can be transfered per seconds?

Assuming 12 bits for each pixel, rather than per color. The 105 bit per second sounds kind of slow, though. A 640 x 480 = 307,200 pixels. Multiply by 12 bits = 3,686,400 bits. So divide by 105 bits per second = 35,109 seconds, or about 9 hours 45 minutes.

### How much memory does a pixel need if it is represented in an uncompressed format?

A hex color is represented by three different levels of the RGB (Red, Green and Blue) colours. Each of which is given a level of shade. To represent this the colors usually have a hexadecimal value for each of the RGB which is made up of two numbers each ranging from 0-f so ff would represent completely on. If you were to have all three red, green and blue completely on or ffffff then you… Read More
