VGA is a descriptor that usually refers to 640×480 resolution, which is the same resolution of a standard definition television. Webcams that are VGA are not considered high-definition webcams. These are entry-level webcams that shoot video at a resolution of 640×480 pixels, or . 3 megapixels or below.

What is 640×480 aspect ratio?

The two most common aspect ratios for video are 4:3 (e.g. 640×480) and 16:9 (1920×1080 or 1080p). With vertical video, popular for mobile device recording, the common aspect ratio numbers get reversed and 16:9 becomes 9:16.

How do I calculate pixel file size?

If the pixel dimensions are given, multiply them by each other and the bit depth to determine the number of bits in an image file. For instance, if a 24-bit image is captured with a digital camera with pixel dimensions of 2,048 x 3,072, then the file size equals (2048 x 3072 x 24)/8, or 18,874,368 bytes.

How much memory is required to store a 640×480 grayscale image?

A 640 X 480 8-bit color image would require 307.2KB of storage, (the same as 8-bit grayscale).

How is pixel ratio calculated?

How to calculate aspect ratio?

  1. Take your original height. In our example, it will be 1200 pixs.
  2. Take your original width.
  3. Divide the height by the width, e.g. 1200 / 1600 = 0.75.
  4. Multiply the quotient by the preferred width, e.g. 0.75 * 300 = 225.
  5. The resulting figure is your new height given in pixels.

How do I calculate aspect ratio?

To create an exact aspect ratio, divide the height by the width. For example: 2:3 aspect ratio: 3 ÷ 2 = 1.5, so you’d drag the slider to 150.

How many bytes are needed to store an image with a resolution of 640×480?

A 640 X 480 monochrome image would require 38.4KB of storage. A grayscale image, (like the example at the right– >), usually requires that each pixel be stored as a value between 0 – 255 (byte).

How do I calculate the size of an image?

To figure out the image size, just follow these simple steps:

  1. Multiply the width and height of the image, in pixels, to get the total pixel count.
  2. Multiply the total pixel count by 3 to get the image size in bytes.
  3. Divide the number of bytes by 1024 to get the image size in kilobytes.
