An information display apparatus comprising: a display unit which includes a screen for displaying an image; a touch detection unit which detects a touch position of an object on the screen of the display unit; a counting unit (10, 32) which determines whether a plurality of touch positions are detected; a motionlessness detection unit which detects a motionless touch position which is motionless for a predetermined time period in the plurality of detected touch positions; and a behaviour detection unit which detects a behaviour of a touch position other than the motionless touch position detected by the motionlessness detection unit among the plurality of detected touch positions; characterized in that the information display apparatus further comprises: an instruction detection unit (10, 35) which detects a frame advance or a frame backward instruction corresponding to the behaviour of the touch position detected by the behaviour detection unit; and a control unit (10, 37) which controls, in accordance with the motionless touch position detected by the motionlessness detection unit and the frame advance or frame backward instruction detected by the instruction detection unit, the display unit to: reduce a display area of a kept image, which is the image being displayed on the display unit when the motionless touch position is detected, to a predetermined size; continue displaying the reduced kept image; and carry out the frame advance or frame backward instruction so that an image other than the reduced kept image is also displayed. a display unit which includes a screen for displaying an image; a touch detection unit which detects a touch position of an object on the screen of the display unit; a counting unit (10, 32) which determines whether a plurality of touch positions are detected; a motionlessness detection unit which detects a motionless touch position which is motionless for a predetermined time period in the plurality of detected touch positions; and a behaviour detection unit which detects a behaviour of a touch position other than the motionless touch position detected by the motionlessness detection unit among the plurality of detected touch positions; characterized in that the information display apparatus further comprises: an instruction detection unit (10, 35) which detects a frame advance or a frame backward instruction corresponding to the behaviour of the touch position detected by the behaviour detection unit; and a control unit (10, 37) which controls, in accordance with the motionless touch position detected by the motionlessness detection unit and the frame advance or frame backward instruction detected by the instruction detection unit, the display unit to: reduce a display area of a kept image, which is the image being displayed on the display unit when the motionless touch position is detected, to a predetermined size; continue displaying the reduced kept image; and carry out the frame advance or frame backward instruction so that an image other than the reduced kept image is also displayed. an instruction detection unit (10, 35) which detects a frame advance or a frame backward instruction corresponding to the behaviour of the touch position detected by the behaviour detection unit; and a control unit (10, 37) which controls, in accordance with the motionless touch position detected by the motionlessness detection unit and the frame advance or frame backward instruction detected by the instruction detection unit, the display unit to: reduce a display area of a kept image, which is the image being displayed on the display unit when the motionless touch position is detected, to a predetermined size; continue displaying the reduced kept image; and carry out the frame advance or frame backward instruction so that an image other than the reduced kept image is also displayed. reduce a display area of a kept image, which is the image being displayed on the display unit when the motionless touch position is detected, to a predetermined size; continue displaying the reduced kept image; and carry out the frame advance or frame backward instruction so that an image other than the reduced kept image is also displayed.
