    Abstract: Disclosed herein is an apparatus and method for providing streaming-based game images. The apparatus for providing streaming-based game images includes an image capturing unit for capturing an image. An image distribution unit distributes pixels constituting the image captured by the image capturing unit depending on resolutions determined by a player and a watcher, and divides an original resolution image into one or more resolution images depending on resolutions desired by the game player and the watcher. A video encoder unit activates a plurality of video encoders depending on a number of images obtained from distribution of the image distribution unit and compresses the images from the image distribution unit. A network communication unit transmits the images compressed by the video encoder unit to a terminal of the game player or a terminal of the watcher depending on the determined resolutions.
