Question

A camera detector has an array of 1920 by 1536 pixels . A colour depth of 16 bits is used . Calculate the size of a photograph taken by this camera , giving your answer in MiB

Dont spam or else im gonna report you

Answer 1

The size of the photograph taken by this camera is 5.6 MiB.

To calculate the size follow given steps:

Step 1: Multiply the detectors number of horizontal pixels by the number of vertical pixels to get the total number of pixels of the detector.

Step 2: Multiply total number of pixels by the bit depth of the detector (16 bit, 14 bit etc.) to get the total number of bits of data.

Step 3: Dividing the total number of bits by 8 equals the file size in bytes.

Step 4: Divide the number of bytes by 1024 to get the file size in kilobytes. Divide by 1024 again and get the file size in megabytes.
