How to open file with .JPS extension?

The .JPS file extension is associated with a stereo or 3D image format known as Stereo JPEG Image. It is commonly used to store and share high-resolution digital photographs and images, as well as 3D models that contain stereo data. The JPS format was developed by the Joint Photographic Experts Group (JPEG), which is a joint standardization committee of the International Standards Organization (ISO) and the International Electrotechnical Commission (IEC). The JPS format is derived from the popular JPEG image file format, but instead of just two color channels, i.e red and blue, it allows three channels: red, green and blue. This means that multiple views can be encoded in the same file, making it suitable for stereo and 3D applications.

Structure of JPS Files

JPG files are stored using the same data structures as JPEG files. They consist of several components including the bitstream, quaternary table, Huffman coding tables, hierarchal tables, MCU capsule headers and the image data itself. As with regular JPEG images, compression is applied to each of the three color channels in order to reduce file size. Color data is broken up into separate blocks known as “macroblocks” before being compressed. Each macroblock is then encoded using either DCT (discrete cosine transform), VLC (variable length coding) or both.

In addition to being limited to three channels, JPS files also offer support for image rotation through what is referred to as a “perspective transformation”. This feature allows for two different images to be stored within one file, creating a 3D effect when viewed through various imaging programs. JPS files use the same compression algorithms as JPEG files and are usually smaller than their standard counterparts due to their shorter headers and smaller number of image channels. Commonly used related file extensions include .JPEG, .JFIF, .JPE, .JPG, and .JXR.
