Question

Размер фотографии с разрешением 1280×768 пикселей равен 240 Кб. Сколько бит памяти используется для кодирования одного пикселя?

Answer 1

Ответ: 2

Объяснение:

240*2^13 и все это поделить на 1280*768

Будет 2, то есть 2 бита на один пиксель

Answer 2

To calculate the number of bits used to encode one pixel, we need to know the size of the photo (in kilobytes) and the resolution of the photo (in pixels). We have the size of the photo as 240 kilobytes and the resolution as 1280×768 pixels.

To find the number of bits used for one pixel, we can use the following formula:

Number of bits per pixel = (Size of the photo in bits) / (Total number of pixels)

First, let's convert the size of the photo from kilobytes to bits: 240 KB = 240 * 1024 bytes = 245760 bytes Since 1 byte is equal to 8 bits: 245760 bytes = 245760 * 8 bits = 1966080 bits

Now, calculate the total number of pixels in the photo: Total number of pixels = 1280 (width) * 768 (height) = 983040 pixels

Now, we can find the number of bits used to encode one pixel: Number of bits per pixel = 1966080 bits / 983040 pixels ≈ 2 bits per pixel

So, approximately 2 bits of memory are used to encode one pixel in this photograph.
