A digital image is a representation of a physical or natural scene in the form of a two-dimensional array of discrete values called pixels. The process of digitizing an image involves three main steps: sampling, quantization, and coding.
What is the digital image about?Sampling refers to the process of dividing the continuous image into a discrete grid of pixels. Quantization involves assigning a numerical value to each pixel, based on its intensity or color, and rounding it to the nearest integer value. Finally, coding involves representing these numerical values as binary codes to store or transmit the image.
The elementary point of a Bitmap image is called a "pixel" (short for "picture element").
White and black colors are obtained by additive synthesis by combining light of different wavelengths. White light is created by adding together all the colors of the visible spectrum, while black is the absence of light.
The size of the images can be calculated by multiplying the width by the height. Therefore:
An image with 2560 pixels in width and 1920 in height has a size of 4,915,200 pixels.An image with 200 pixels in width and 150 in height has a size of 30,000 pixels.An image with 405 pixels in width and 1230 in height has a size of 498,150 pixels.Learn more about digital image from
