Image File Compression

Image compression is a process that uses algorithms to decrease the size of a file. High-resolution cameras produce large image files, ranging from hundreds of kilobytes to megabytes, per the camera’s resolution and the image-storage format capacity. High-resolution digital cameras record 24 megapixel (1 MP = one million pixels) images, or more, in true color. For example, an image recorded by a 24 MP camera; since each pixel uses 3 bytes to record true color (red, green, blue), the uncompressed image would occupy 72 MB of memory—a great amount of digital storage for one image, given that cameras must record and store many images to be practical. Faced with large file sizes, both within the camera and a storage disk, image file formats were developed to store such large images. An overview of the major graphic file formats follows (Frantiska, 2006).

There are two types of image file compression algorithms: lossless and lossy.
