Patent ID: 7573462

Claim:
An image display apparatus for displaying an image on neighboring first and second display screens, comprising: an output unit that outputs to an external device pointing information based on a position pointed by a pointer; a first determining unit that determines whether or not the position pointed by the pointer is moved from an edge of the first display screen to the second display screen after the pointer has come into continuous contact with the first display screen; an acquiring unit that acquires a time period elapsed during which the pointer is out of contact with the edge of the first display screen before the pointer comes into contact with the second display screen, when the first determining unit determines that the pointer is moved from the edge of the first display screen after the pointer has come into continuous contact with the first display screen; and a second determining unit that determines whether or not the acquired elapsed time period is less than a predetermined time period, wherein said output unit outputs to the external device the pointing information indicative of the pointer continuously pointing from the position where the pointer is out of contact from the first display screen to the position where the pointer comes into contact with the second display screen, in a case where said second determining unit determines that the acquired elapsed time period is less than the predetermined time period, and wherein said output unit outputs to the external device the pointing information indicating that the pointer points at the second display screen after outputting the pointing information indicating the pointer pointed at the edge of the first display screen, in a case where said second determining unit determines that the acquired elapsed time period is longer than the predetermined time period.
