How many pixel 30 KB?
30kb = ? pixel?
How many colors are possible if 8 bits pixel is used?
256, 8 bits per pixel = 2^8 colours.
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 per pixel are needed to represent a black and white image?
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.
If a tv screen has 525 scan line and an aspect ratio of 3 is to 4 and if each pixel contains 12 bits worth of intensity information how many bits per second are required to 30 frames each second?

Do vector graphics have pixels?
No, they are shape based and do not have pixel bits.
How many different choices of colors are possible if you use 24 bits per pixel?
You can represent a maximum of 2^24 colors in RGB. This equals to 16777216 possible colors.
What is 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 make it more accurate, ie dithering). If the palette of colors is smaller than 256 colors than a single byte (8 bits) is all that is needed per pixel to indicate what color in the palette should belong at that pixel.
Do you understand by data compression?
Data compression allows for encoding information by using fewer bits.
The number of bits devoted to each pixel is called?
A hui tebe, sosni!! Lol!!
If a tv screen has 525 scan line and and aspect ratio of 3 is to 4 and if each pixel contains 12bits worth of intensity information how many bits per second required to 30 frames each second?
They will require 24 bits per second to 30 frames each second.
What does bitmap mean?
A bitmap is a series of bits which represents a rasterized graphic image, each pixel being represented as a group of bits.
