How many colors can a PNG image contain?
PNG files can be 24 bit per pixel or 32 bit per pixel. The 24 bit variety stores 2^24 or 16777216 colors. The 32 bit variety stores 2^32 or 4294967296 different colors.
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.
How many pixel 30 KB?
30kb = ? pixel?
Describe Mpeg i p b frames storage size?
Taken from http://bmrc.berkeley.edu/frame/research/mpeg/mpeg_overview.html The typical data rate of an I-frame is 1 bit per pixel while that of a P-frame is 0.1 bit per pixel and for a B-frame, 0.015 bit per pixel.
What bitmap file format has the lowest resolution only 8 bit per pixel?

What are the most important characteristics of an image?
Technical characteristics:- number of colors (how many bits per pixel are supported)- image size (width x height in pixels - also call image resolution horizontal, respectively vertical)- file size (size in bytes of the file where the image is saved)- display/print resolution, usually in dots per inch/cm (a description on how to output the image)Subjective impressions (for example when evaluating photographs)- subject of the image- background- type of the composition (surreal, landscape...)A pixel is a single rectangular element of an image. A pixel has a defined color.
How many colors 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 in 8 bit per channel or 24 bits per pixel image is 256x256x256 colors or in particular exact number of possible colors is 16777216.
What are the types of images?
Types of images are: 1.Compressed image 2.RGB image (True Color Image & has 3 pixels ) 3.RGBA image (True Color Image & has 4 pixel or more ) 4.Grayscale image (Black & White) 5.Palette image (16 colors per pixel ) All i want is to " Like" ! Thanks !
What is a bit in digital circuit?
Bit means 'Binary Digit' In a Digital Circuit, the amount of 'bits' is usually the measure of binary digits which can logically be processed. 8 bits per byte.
What is meant that bitmap graphics are resolution dependent?
bitmap or raster images are in other words pixel images and every pixel image must have resolution, resolution is number of pixels per inch, cm
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.
Working principle of digital camera?
Working principle of a digital camera: · Capturing image: lenses focused the light rays come from the object made into a coherent image. Diaphragm determines amount of light to be entered and shutter speed determines time of exposure. Then lights made fall onto sensor (CCD) to get corresponding electric charge. · Binary system processing: Where there is word digital, the word binary also found there. To convert analogue signal (electric charge from photosites) to Digital signal in binary form a ADC converter is used. Each of the charge stored in photosites assigns to a binary value, storing them as pixels. A pixel is a point sample of an image which contains three basic color (RGB) components. Pixel per square inches determines the resolution of the camera, which indicates the size and quality of image. In next post I'll discuss more about pixel and resolution. · Compression and storage: Once the image is digitalized, it is compressed by a microprocessor and stores as image file (JPEG, TTF etc.) From the age of invention of camera, evolution of this has been taken place and which will continue. Now digital cameras are being developed by adding new features like video recording, music playing, even GPS has embedded in it.
