Apr 10, 2019 · 0. (Assuming there is no compression) 8 Bits = 1 Byte Therefore, the size of one pixel is 1 Byte. Total number of pixels = 800 × 600 Total size: (800 × 600 × 1) Bytes = 480000 Bytes = 48 × 10 4 Total size of storage: 512 MB = 512 × 10 6 bytes Number of images that can be stored = (512 × 10 6)/ (48 × 10 4) ≈ 1066.
Jan 9, 2019 · For example there is a 2400x600px image with a file size of 1.81MB. Photoshop's save for web command creates a 540KB file at 60 quality and same dimensions. This is about 29% of original size. The original uncompressed size is 2400 x 600 x 3 = 4,320,000 bytes (4.1 MB), because 24 bit color is always three bytes of RGB data per pixel. There is ...
Aug 4, 2010 · Calculating the file size of a scanned image (uncompressed) Uncompressed file size = Resolution in dpi (horizontal ) x Resolution (vertical) x Height (inches) x width (inches) x color depth. Example 1 - scanning an A4 page in 200 dpi in B&W. = 200 x 200 x 8.27 x 11.69 x 1. = 3,867,052 bits. = 483,381 bytes. = 472 Kb.

It can be veryconfusing. Understanding some of the details about how photographs are stored on disk, how they are displayed, and how they are printed can allow you to make a dramatic difference in the size of documents, webpages, emails, and more. It isn’t terribly complicated to understand, but the details can be a little confusing if you don’t kn...
A pixel (short for “picture element”) is a dot. Seriously, that’s all it is. One dot. We can do things with that dot, like give it a color, and I’ll get to that in a moment, but at its most fundamental level, a pixel is nothing more than a single dot. That was easy.
Computer display devices, like the screen on which you’re reading this, is nothing but a rectangle of pixels. The rectangle is so many pixels wide (horizontally) and so many pixels high (vertically). For example, one screen I use is a rectangle that is 1,920 pixels wide and 1,200 pixels high, or simply “1920 × 1200”. That’s referred to as the resol...
With pixels and resolution under our belt, we can start talking about size. Image size can be a confusing concept because there are two different kinds of size we’re talking about: 1. The physical size of the image displayed on screen or printed on paper. We measure that in inches or pixels. 2. The size of the file— like “.jpg” or “.png” files — in...
We can’t really talk about the size of an image in bytes without first discussing how color is represented in an image.
The magic acronym when displaying pictures is DPI, or Dots Per Inch. Remember, pixels are dots, so when we talk about DPI, we’re really talking about how tightly packed the pixels are when they’re displayed (or “rendered”) on an output device.2 For example, many LCD displays present around 75 pixels (or dots) per inch. It varies widely, depending o...
The images above were taken as a full-color photo taken on my 12-megapixel camera. If displayed at 100% resolution (meaning each pixel in the image is displayed on a single pixel on the monitor), that 4,288 by 2,848 pixel photo would require a 75 DPI monitor nearly five feet wide by a little over three feet high to display completely. If printed at...
Make your pictures smaller. Think about how your image is going to be used, and resize the image for that target use. Make it as big as necessary for that use, but no bigger. Is it simply going to be viewed on a screen, or will it get printed? Understand the typical DPI that would be used for each so you can pick an appropriate size in pixels. Want...
As I said at the beginning, all of this can be confusing, and your head might be spinning by now. I get it. My advice to you is to pick an image and play with it. Specifically: 1. Make a copy of your original image as it came from your camera or wherever else. This is important, because no matter what you do next, you’ll always have the image back ...
Aug 4, 2020 · FILE SIZE is calculated by multiplying the surface area of a document (height x width) to be scanned by the bit depth and the dpi2. Because image file size is represented in bytes, which are made up of 8 bits, divide this figure by 8. Formula 1 for File Size. File Size = (height x width x bit depth x dpi2) / 8.

Why is a 24-bit image more detailed than a 4-bit image?
If the usual 24-bit color image, that data size will be 3 bytes per pixel. If 24 megapixels, then 72 million pixels, but which due to the 1024 thing, MB will be about 68.7 MB. Again, that is size in memory, and image data is usually compressed smaller while in the image file (like .JPG).
