JPE to ARW

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.

ARW is an uncompressed file format with a digital image of a sufficiently large size, which Sony has created and successfully uses for raw images of its own digital cameras (Sony Digital Camera Raw Image). That is, files of this format are RAW. To open them, you need to use special graphics programs. Any ARW file has a set of basic information. 1) Information from the manufacturer. This includes information about the camera model, filters, lens, sensitivity, color space, white balance, etc. 2) EXIF ​​information. Details of aperture, exposure time, flash, and more. 3) Thumbnail image. Usually about 12 MPx, color, compression. 4) Full-size image with a large color depth. Typically, 12 bits per pixel, or 4096 brightness levels. A full-sized image can be saved as information about different colors. Red, blue, green. The image is collected, and the result is a color photo. Due to this and due to the large color depth of RAW, this type of file is perfect for processing graphics. Better than jpg. The format provides the ability to save many details. It has more options for adjusting color, restoring details from shadows and reducing noise.
