Image File Size Solution

STEP 0: Pre-Calculation Summary

Formula Used

Image File Size = Image Resolution*Bit Depth/8000
S_i = R_i*B_d/8000
This formula uses 3 Variables

Variables Used

Image File Size - (Measured in Bit) - The Image file size is the amount of space that the image file takes up on your memory card, or internal memory if your camera has one. It is measured in megabytes.
Image Resolution - (Measured in Pixel) - The Image Resolution is the image width multiplied by the image height.
Bit Depth - (Measured in Bit) - The Bit depth is the second factor affecting image file size is bit depth. Bit depth is the storage space each pixel needs to represent the range of different colours.

STEP 1: Convert Input(s) to Base Unit

Image Resolution: 1000 Pixel --> 1000 Pixel No Conversion Required
Bit Depth: 34 Bit --> 34 Bit No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_i = R_i*B_d/8000 --> 1000*34/8000

Evaluating ... ...

S_i = 4.25

STEP 3: Convert Result to Output's Unit

4.25 Bit --> No Conversion Required

FINAL ANSWER

4.25 Bit <-- Image File Size

What are the different types of image file format?

Image files can come in many different file formats that we can group into two categories: raster and vector images. A raster image file contains an array of pixels of various colors arranged in a grid to form a picture.

Difference between image size and file size?

This represents the physical size and resolution of an image measured in pixels. A higher image size setting means a larger picture and bigger file size. This is the amount of space that the image file takes up on your memory card, or internal memory if your camera has one.

How to Calculate Image File Size?

Image File Size calculator uses Image File Size = Image Resolution*Bit Depth/8000 to calculate the Image File Size, The Image File Size formula is defined as is the amount of space that the image file takes up on your memory card, or internal memory if your camera has one. It is measured in megabytes. It is measured in megabytes. The actual file size depends on the image size and image quality settings selected on the camera. Image File Size is denoted by S_i symbol.

How to calculate Image File Size using this online calculator? To use this online calculator for Image File Size, enter Image Resolution (R_i) & Bit Depth (B_d) and hit the calculate button. Here is how the Image File Size calculation can be explained with given input values -> 4.25 = 1000*34/8000.
