Determine the number of bytes necessary to store an uncompressed RGB color image of size 640 × 480 pixels using 8, 10, 12 and 14
dexar [7]

Answer:

For 8 bits / Color Channel: 921, 600 bytes.

For 10 bits / Color Channel: 1,152,000 bytes.

For 12 bits / Color Channel: 1,382,400 bytes.

For 14 bits / Color Channel : 1,612, 800 bytes.

Explanation:

Un uncompressed RGB color image of 640 pixels wide by 480 pixels height (VGA resolution) uses 3 samples of x bits fin order to represent the quantity of each primary color (red, green and blue) in a given pixel of the image.

So, if we use 8 bits/ sample, we can calculate the bytes needed to store a complete image as follows:

640*480*3*8 bits = 7, 372,800 bits. (1)

As, by definition, 1 byte= 8 bits, we have:

Nº of bytes = 7,372,800 / 8 = 921,600 bytes. (2)

In order to get the bytes needed to store the same image, using 10, 12 and 14 bits/ sample, all we need is replacing 8 by 10, 12 and 14 in (1), and then dividing by 8 as in (2).

Proceeding in this way we obtain:

640*480*3*10 = 9,216,000 bits ⇒    1,152,000 bytes.

640*480*3*12 = 11,059,200 bits ⇒   1,382,400 bytes.

640*480*3*14=   12,902,400 bits ⇒  1,612,800 bytes.

Create and test a user-defined function named ufnFullName that combines the values of the two parameters named FirstName and Las
8090 [49]

Answer:

   public static String ufnFullName(String Fname, String Lname){

       String FullName = Fname+" "+Lname;

       return  FullName;

   }

Explanation:

Using Java programming language, the function is created to accept two String parameters (Fname and Lname)

These are concatenated into a new String FullName and returned by the function

See below a complete code that prompts users to enter value for first and last names then calls this method to display the full name

<em>import java.util.Scanner;</em>

<em>public class FullName {</em>

<em>    public static void main(String[] args) {</em>

<em>        System.out.println("Enter First Name");</em>

<em>        Scanner in = new Scanner(System.in);</em>

<em>        String Fname = in.next();</em>

<em>        System.out.println("Enter Last Name");</em>

<em>        String Lname = in.next();</em>

<em />

<em>        System.out.println("Your Full Name is "+ufnFullName(Fname,Lname));</em>

<em>    }</em>

<em>    public static String ufnFullName(String Fname, String Lname){</em>

<em>        String FullName = Fname+" "+Lname;</em>

<em>        return  FullName;</em>

<em>    }</em>

<em>}</em>
