A game providing server which decreases the latency in a cloud gaming service is disclosed. In the game providing server, a graphics processor generates a picture of a game to be distributed to a client through a network. A memory stores picture data generated by the graphics processor. The graphics processor converts the color system of the picture data of a predetermined data amount using it as a trigger that the picture data of the predetermined data amount is stored into the memory. An encoding unit converts the picture data of a predetermined color system into encoded data to be used upon distribution of the picture data to the client through the network. The graphics processor changes the picture data stored in the memory to picture data of a color system which can be encoded by the encoding unit.
