Information processing apparatus for displaying first image data and for transmitting higher resolution second data to portable projector and image data transmittion method used in the apparatus

摘要

An information processing apparatus performs communication with an external device (2) which displays received image data. The information processing apparatus includes a unit for generating second screen image data from first screen image data which is stored in a memory (15) in the information processing apparatus by a program executed by the information processing apparatus. The resolution of the second screen image data is lower than that of the first screen image data. The information processing apparatus also has a display device (111) which displays the second screen image data, a unit for acquiring the first screen image,data from the memory (15), and a unit for transmitting the first screen image data to the external device. <IMAGE>
