IMAGE DISPLAY CONTROL PROGRAM, IMAGE DISPLAY CONTROL METHOD AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an image display control program and an image display control method capable of optimizing display control according to individual variation in posture of a user or the way the user moves a terminal, in image display control for changing display content depending on an attitude of the terminal, and to provide an image display device using the image display control program and the image display control method.SOLUTION: Attitude information of a device detected by an attitude detection unit is sequentially accumulated, and display control is performed using an image display feature associated with an index corresponding to a relative attitude of a portable terminal, among multiple image display feature information. When the portable terminal is rotated beyond an effective rotational angle, both or one of the effective rotational angle and the range of the effective rotational angle are updated. A reference attitude is redefined so that a position at the time before the excessive rotation is determined to have been finished becomes a new threshold value of the effective rotational angle. This processing enables optimized continuous images to be displayed quickly, regardless of the individual variation in the way the user operates the portable terminal.SELECTED DRAWING: Figure 7
