Question

what is pixel and resolution in computer graphics​

Answer 1

In computers, resolution is the number of pixels (individual points of color) contained on a display monitor, expressed in terms of the number ofpixels on the horizontal axis and the number on the vertical axis. ... Typically, PC monitors have somewhere between 50 and 100 pixelsper inch.

Answer 2

Short for Picture Element, a pixel is a single point in a graphic image. Graphics monitors display pictures by dividing the display screen into thousands (or millions) of pixels, arranged in rows and columns. The pixels are so close together that they appear connected.

The resolution can be defined in many ways. Such as pixel resolution, spatial resolution, temporal resolution, spectral resolution. Out of which we are going to discuss pixel resolution.

You have probably seen that in your own computer settings, you have monitor resolution of 800 x 600, 640 x 480 e.t.c

In pixel resolution, the term resolution refers to the total number of count of pixels in an digital image. For example. If an image has M rows and N columns, then its resolution can be defined as M X N.

If we define resolution as the total number of pixels, then pixel resolution can be defined with set of two numbers. The first number the width of the picture, or the pixels across columns, and the second number is height of the picture, or the pixels across its width.

We can say that the higher is the pixel resolution, the higher is the quality of the image.

We can define pixel resolution of an image as 4500 X 5500.
