Question

найти обьем видеопамяти для четырех цветного изображения размером 640x480

Answer 1

4цвета = 2 бита

640*480*2=614400бит

Answer 2

Объем видеопамяти = разрешение картинки*глубину цвета.

$2^{i}=N$ , где i - глубина цвета, N количество цветов изображения.

глубина цвета = логарифму 4 по основанию 2=2

 Объем видеопамяти = 640*480*2=614400бит=75 килобайт

 

 

 

 

 

 

 

Answer 3

Calculating Video Memory for a Four-Color Image of Size 640x480

To calculate the video memory required for a four-color image of size 640x480, we can use the formula:

Video Memory = Image Width x Image Height x Color Depth

Where: - Image Width = 640 pixels - Image Height = 480 pixels - Color Depth = Number of bits per pixel to represent color information

Determining the Color Depth

From the search results, we find the following relevant information: - Source mentions "640x480 32..." which indicates a color depth of 32 bits per pixel. - Source also mentions "640 480" in the context of video memory.

Based on this information, we can conclude that the color depth for the image is 32 bits per pixel.

Calculating Video Memory

Using the formula with the given values: Video Memory = 640 x 480 x 32

Now, let's calculate the video memory: ``` Video Memory = 640 x 480 x 32 Video Memory = 9,830,400 bits ```

Therefore, the video memory required for a four-color image of size 640x480 is 9,830,400 bits.
