Abstract: The image processing device stores a fixed horizontal resolution and a fixed vertical resolution established in advance for use in resolution conversion of an input image. The first resolution converter of the image processing device converts the input image to a fixed resolution-converted image so that at least a horizontal resolution of the fixed resolution-converted image is equal to the fixed horizontal resolution. The second resolution converter of the image processing device converts the fixed resolution-converted image output from the first resolution converter to the display resolution-converted image having the desired horizontal and vertical resolutions.

Abstract: An electromechanical device includes a first drive member having a magnetic coil, a second drive member capable of moving relatively to the first drive member, and a control section adapted to drive the magnetic coil and to perform regeneration of energy from the magnetic coil when decelerating the second drive member, and the control section includes a first regeneration mode of setting a first regenerative interval centered on a zero crossing point of an induced voltage caused in the magnetic coil, and performing the regeneration.

Abstract: A projector in accordance with the invention includes an image processing unit that includes an image quality adjustment unit and a keystone correction unit. The image processing unit corrects the keystone error, in which a distorted image data is generated and a black part is added to the distorted image, after the image quality adjustment, such as brightness adjustment, is performed for the input digital image data. This processing order reduces or prevents the black part from being affected by the brightness adjustment and becoming a gray part, thereby enhancing the quality of the projected image.
