its store 1bit per pixel
To calculate the pixel size of an image, you need to divide the width or height of the image in pixels by the physical size of the image in inches. This will give you the pixel size per inch.
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.
The equivalent pixel resolution of an image at 300 dpi is 300 pixels per inch.
30kb = ? pixel?
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.
Oh, dude, a PNG image can technically contain up to 16.7 million colors thanks to its 24-bit color depth. That's like a whole rainbow on steroids! So, yeah, you can pretty much throw any color you want into a PNG image and it'll handle it like a champ.

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.
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.
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.
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 !
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
