Question

Определите разрешающую способность изображения, если глубина цвета 4 бита, а информационный объем изображения 2,5 кбайт. Сколько цветов в палитре?  Помогите пожалуйста,очень нужно 

Answer 1

Цветов: 2^4=16
разрешение:
2,5*1024*8=20480 бит
теперь 20480/4=5120 пикселей в изображении)) это и будет разрешающая способность)

Answer 2

Resolution of the Image

The resolution of an image refers to the number of pixels it contains. In this case, the depth of color is given as 4 bits, and the information volume of the image is 2.5 kilobytes (kB). To determine the resolution of the image, we need to calculate the number of pixels.

The formula to calculate the number of pixels is as follows:

Number of pixels = Information volume / (Depth of color / 8)

Let's calculate the number of pixels using the given information volume and depth of color:

Number of pixels = 2.5 kB / (4 bits / 8) = 2.5 kB / 0.5 bytes = 5 kilopixels

Therefore, the image has a resolution of 5 kilopixels.

Number of Colors in the Palette

To determine the number of colors in the palette, we need to consider the depth of color. The depth of color is given as 4 bits, which means that each pixel can represent 2^4 = 16 different colors.

Therefore, the palette for this image contains 16 colors.

I hope this helps! Let me know if you have any further questions.
