A two mode image displaying apparatus including a light source, an image dividing unit, a displaying unit, and a control unit is provided. The light source is adapted to provide a light beam. The image dividing unit is disposed on the transmission path of the light beam. The image dividing unit is adapted to be switched to include a three-dimensional (3D) mode area and a two-dimensional (2D) mode area. The light source is adapted to be switched to include a first area and a second area. The displaying unit is disposed on the transmission path of the light beam. The control unit is electrically connected to the light source, the image dividing unit, and the displaying unit. The control unit executes a boundary brightness compensation by adjusting brightness of at least one of the boundary of a 3D image area and a 2D image area of the displaying unit and the boundary of the first area and the second area of the light source. An adjustment method of image brightness is also provided.
