In an image projection device in which a projected image can be controlled or operated by gesture, the responsiveness (operability) and/or the usability are improved. The image projection device includes a sensor element to detect a gesture and a control section to generated an operation signal to control (for example, to scroll images or to feed image frames) a projected image projected according to a gesture detected by the sensor element, wherein the control section generates the operation signal when the sensor element detects a gesture in a first direction parallel to the projection surface of the projected image, and when the sensor element detects a gesture in a second direction perpendicular to the projection surface, the control section suspends generation of the operation signal.
