All about Pixel ?

Pixel -

Everyone always uses this word in our daily life. Like my phone camera ha 10 mega-Pixel camera.

like this. But the question is that Do you know what is a pixel.

Let's go for knowledge about the pixel.

When we talk about Display, Video, Image etc. where we actually talk about Quality which means normally we talk about in term of Resolution. Must be Full HD, 4K, 8K like this.

Just look at this picture

If Zoom a picture then we see some tiny boxes , all this tiny boxes is collective image, all the small tiny boxes are called Pixels.

we can easily say 

                             Pixel=Picture+Element

A pixel is a small element of the picture. basically, each pixel represents a color which is a combination of color Red, Green, Blue (RGB).   

    We can create millions of color with RGB(red, green, blue).

Each pixel contains three RGB transistors which will we on and of depending on the situation or Color. 

If we watch the Full HD Video which means each frame will have 1920 X 1080 =2073600 Pixels.

Each pixel will have three RGB transistors so in full HD display contain.

                                     2073600 X 3 = 6220800 RGB transistors.

so the question is that how does my computer show a picture.

each pixel contains 8-Bit binary code that converts in corresponding RGB color.

Like-  

                                                        11011001

                                                        01001010

                                                        10010011

           for easy to understand we convert it to Hexadecimal Code.

                          like- FFFFFF

The best unit of this is PPI( pixel per inch) which means how many pixel is situated in a inch.

I hope to Know you are able to Define pixel in anywhere.
