Abstract: An image display device includes an image display component, a detector, and an error determination component. The image display component is configured to project on a projection surface a projection image with at least first and second input objects for a user input operation using an indicator. The first and second input objects are adjacently arranged in the projection image with a spacing therebetween. The detector is configured to detect the indicator in a detection range that extends in a height direction of the projection surface. The error determination component is configured to determine that the user input operation of the second input object is erroneously detected in response to the detector continuously detecting the indicator in regions of the detection range corresponding to the first input object, the spacing and the second input object, respectively.

Abstract: Disclosed is a scaling process system including a replay apparatus and a video output apparatus which are connected via a HDMI, wherein each of the video output apparatus and the replay apparatus respectively comprises a between-pixel interpolation method table, wherein the video output apparatus including a request signal transmission device to transmit a request signal, a between-pixel interpolation method information receiving device to receive the between-pixel interpolation method information, a determining device to determine which of between-pixel interpolation method information of the replay apparatus or between-pixel interpolation method information of the video output apparatus is more high-performance, a deciding device to decide an apparatus to be used for the scaling process, and a control device to control the apparatus which is decided by the deciding device so as to carry out the scaling process, and wherein the replay apparatus including a request signal receiving device to receive the reque
