Converter JPE to MEF

JPE is the graphic format of the raster image category. It was developed by the standards committee of the Joint Photographic Experts Group. It is a 24-bit compressed graphics format. Typically, it is used for web resources. In most cases, it is used for photographs or images in which there are many colors. Also well suited for many digital cameras to store digital photos. Images that have this extension use lossy compression. And because the quality of individual photos is getting worse. The greater the compression, the less quality the image becomes. The purpose of JPE files is to compress photorealistic images with small color losses. Provides the ability to achieve high compression ratios. We emphasize that usually the maximum compression of graphic information leads to some loss of information. That is, the compression algorithm changes the original data so that the image that is obtained after restoration will be different from the original image, that is, compressed. This compression method is used to work with full-color images that have high photographic quality. During compression, the Discrete-Cosine Transform (DCT), Huffman’s Code quantization and coding are used.

MEF is Mamiya's own RAW format. A high-quality Japanese brand is well known to those who take professional photographs. His story began in the 1940s. It was then that camera designer Seiichi Mamiya and investor Tsunejiro Sugawara created Mamiya. Mamiya ZD cameras are the first mid-format digital cameras. The expanded name of the MEF format is Mamiya RAW Image. He gained fame as a format of "digital negatives". Mamiya has developed this format in order to use it in cameras of its own production. At the same time, the main goal was to store the photos in an uncompressed form, so that later they would be processed without losing quality. The format is built on the principle of a RAW file. It contains a complete set of information that is received from the camera lens. RAW images are uncompressed files. They can be customized using image editing software. They are often preferred by professional photographers, because they are tasked with having high-quality images with many details. An MEF file is capable of storing an image as if it had been made into a CCD camera device. In most cases, it is stored on a memory card, and then transferred to a computer in order to edit and publish.
