Aug 21, 2024 · Computer storage is generally measured in multiples of the byte. For example, a 640 MB hard drive holds a nominal 640 million bytes – or megabytes – of data. Byte multiples are made up of exponents of 2 and are generally expressed as a “rounded-off” decimal number. For example, two megabytes or 2 million bytes are 2,097,152 (decimal) bytes.
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.
represented by a single byte; e.g., a dark pixel might have a value of 10, and a bright one might be 230. • Bitmap: The two-dimensional array of pixel values that represents the graphics/image data. • Image resolution refers to the number of pixels in a digital image (higher resolution always yields better quality).
Part of Computing Science Computer systems. ... 168000000/8 = 21,000,000 bytes; ... Bit-mapped images tend to have a larger file size than most vector graphics; Next page. Vector graphics.
The higher the resolution of an image, the larger its file size will be. File size The file size of a bitmap image is calculated using the number of pixels in the image, and its colour depth.
Follow the same steps to calculate the file size of image 3, this time convert the file size from bits too Megabytes. Step 1: Multiply the number of horizontal pixels by the number of vertical pixels: 1600 x 1200 = 1920000 pixels. Step 2: Multiply the total pixels used by the colour/bit depth: 1920000 x 24 = 46080000 bits.

This means that the size of a bitmap image file will increase if either the colour depth or the image resolution increases. File size (in bits) = width (in pixels) × height (in pixels) × colour depth (in bits) For example, a bitmap image has a width of 8 pixels and a height of 8 pixels, with a colour depth of 4 bits. The file size calculation is:
