Solution to User Question: CG_001

 CG Question; Binod asks:

Please provide me the solution :computer graphicsconsider 512 pixels by 512 scan lines with 24 bit true colour.if 5 minutes video is required to capture calculate the total memory requirement

@Binod:
Simple really, 

First determine the number of pixels. 
In this question 512x512 is the number. 

Then determine the bit-depth which is 24bit here. 
Bit-depth represents the number of bits assigned to a pixel in a display device. 

Now the given time duration is 5minutes i.e 300seconds. 

The total memory requirement would be 
= 512 x 512 x 24 x 300 x 1 
= 1887436800bits. 

Divide it by 8 to get Byte value = 235929600Bytes

Divide it by 1024 to get Kilobyte value = 230400Kilobytes

Divide it by 1024 to get Megabyte value = 225Megabytes

This solution assumes the following things:

• The video is being refreshed at only 1 frame per second.
  as seen here ( 512 x 512 x 24 x 300 x 1 ) which represents 1fps
• The video does not undergo any optimizing algorithm to reduce video memory. In real-practice, videos are shot with such algorithms in place which allows it to retain maximum quality with small size.
