Abstract
To shorten the time required to transfer image data from a first information processing apparatus (e.g., an electronic camera) to a second information processing apparatus (e.g., a personal computer) the first information processing apparatus reduces the image data when it is determined that a slow interface is being used. Additionally, the reduced image data being transferred can be altered in size (enlarged or further reduced) prior to compression so that its size is best suited for the particular compression process.
