The SJ1 file type is associated with the Sega SJ-1 DIGIO, a digital camera released by Sega in the late 1990s. These files contain digital images captured by the camera. The SJ-1 DIGIO was among the early digital cameras aimed at the consumer market, and its files are specific to this device's proprietary format. To view or edit SJ1 files, one would typically need specialized software or conversion tools that can interpret this unique format.
A BMP file is an uncompressed raster image comprised of a rectangular grid of pixels. It contains a file header (bitmap identifier, file size, width, height, color options, and bitmap data starting point) and bitmap pixels, each with a different color.
