摘要： In one embodiment, a projector may include a focus adjusting unit, an adjustment image projecting unit, an imaging unit, and a condition indicating unit. The focus adjusting unit adjusts a focus of a projection light according to a manual operation. The adjustment image projecting unit projects an adjustment image containing a portion representing a predetermined pattern by the projection light. The imaging unit shoots a projection surface to which the adjustment image is projected. The specifying unit specifies a focusing condition of the focus on the projection surface by analyzing an image data that is created by the imaging unit. The condition indicating unit displays the specified focusing condition. The adjustment image includes a first portion that includes a bar graph representing the specified focusing condition, and a second portion that represents the predetermined pattern.
