What is Aspect ratio

-

 1) 3000 * 4000= 1,20,00000 pixels

Or 12 megapixel

2) one million pixels= 1 megapixel.

3) You might have heard many times the word megapixel mostly when you mention about your camera details, what does it means?

4) The amount of details that the camera can capture is called the resolution (w*h), and it is measured in pixels.

5) More the Pixel camera has, more detail it can capture and the larger pictures can be without blurry or "grainy".


6) Aspect ratio is ratio of width to height of device.

• Example: 16 inch(horizontal) and 9 inch(vertical) 16:9= 1.77.

Here 1.77 is the Aspect ratio.

* If you want to increase the size of resolution the pixel size has to be decreased and vice versa.

* Resolution is technically the number of Pixel per unit of area.

• Let's have a look to chart of different resolution available.

1) SD(480) Standard Definition

      = 640*480 => 640:480 = 1.3(Aspect ratio).

2) SD(480) = 720*480 =>720:480=>1.5(AR)

3) HD 720 High definition or 720p=> 1280*720 => 1.77(AR).

4) FHD 1080 Full HD or 1080p=> 1920*1080 => 1.77(AR)

5) 2k => 2048*1080 => 1.896(AR)

6) 2k => 2560*1440 => 1.77(AR)

7) 4k => 3840*2160 => 1.77(AR)

   =>  That is  QFHD or Quad FHD

8) 8k or 8k ultra HD=> 7680*4320

Line Basic Concepts

Image
 • We are going to study about Line Basic Concepts on Raster Screen. • so we are going to discuss what are the different ways in which line can be represented on Raster Screen and some of there respective features. 1) Vertical and Horizontal Line  • They have same width. • Straight line.  • Effective spacing is less. • More brighter. 2) 45° Line  • Width is not a constraint.  • Straight line. • More effective spacing. • Less brighter. Explanation:  • Point to remember is when there is more spacing between the points of line less brighter it will be and vice versa.  • But more spacing leads to effectiness in orientation of line. 3) Line with other orientation • In both of the above image the lines are nethier straight nor of same width. • Here points of line that is Pixel is approximated because while drawing the single line at point we get two points one is above the line and another is below the line. • But here approximation doesn't make a wide diffe...

Sample programs

 • We are going to discuss some simple programs in turbo C before going to graphics program that is terminal in graphic mode. • So simple programs in text mode. 1) Program to print Hello world on different line. #include<stdio.h> #include<conio.h> int main() {     int c= 5;      for(int i=0;i<12; i=i+2)     {     gotoxy(c,i);     printf("Hello world!");     c=c+2;     } getch(); return 0; } Explanation: • we have also discussed prior about text mode in Turbo C let's understand it in short. • So this is the image representation of text mode where: 1) screen is divided in Rows and Columns. 2) we have 80 rows and 25 columns 3) Here first coordinate is of column and another is row example: (80,25) • 80 is column and 25 is row only in turbo C text mode it's reverse as it is normally. 4)  program we did above is of Controlling the cursor with the help of function gotoxy( )  it's a functio...

Types of Computer Monitor

 • We all use in are day to day life different types of Computer for instance different color, size, shape, and brand, we also have different types of monitor too. • So let's have a look on different types of monitor available in market • Different types of monitor 1) CRT (Cathode Ray tube) 2) LCD (Liquid Crystal Displays) 3) TFT (Thin Film Transistor) 4) LED (light Emitting Diodes) • There are two type of CRT display available: 1) Raster Scan Display 2) Vector Scan Display • We will discuss both the display one by one, but before that we will study how CRT works? in further post. * You can leave a comment if you have doubt in it.
