Abstract: According to one embodiment, an imaging unit inputs a camera image of surroundings of a vehicle. The surroundings include at least one of a front side and a back side of the vehicle. A first image generation unit generates a mask image to conceal a protection region of personal information included in a region of a first vehicle on the camera image. The first vehicle exists at the front side or the back side of the user's vehicle. A surroundings-monitoring unit decides whether a second vehicle exists at a front side or a back side of the first vehicle by monitoring the camera image. A second image generation unit generates an identification image of the second vehicle when the second vehicle exists. A processing unit generates a composite image by combining the mask image and the identification image with the camera image, and displays the composite image to present to a user of the vehicle.

Abstract: An optical disc reproducing device including rollers configured to carry an optical disc inserted in a slot in an inside direction to a reproduction possible position and to carry the optical disc in an outside direction to a prescribed ejecting position from the reproduction possible position, a plurality of position detecting switches to detect positions of the optical disc in the device, and a carrying control unit configured to control to drive the rollers based on states of the position detecting switches so as to carry the optical disc. The carrying control unit, when the optical disc stops at a position except the reproduction possible position and the ejecting position, drives the rollers to carry the stopped optical disc to the ejecting position, in at least one of cases that a state of any position detecting switch has changed and that any operating key is operated by a user.

Abstract: A disc playback apparatus incorporating a memory that stores data concerning errors or differences between commanded number of tracks to be traversed and the number of tracks actually traversed by an optical pickup actuated by a servo controller. The apparatus further includes a traversed track number computing unit computes the number of tracks to be traversed by the optical pickup when the optical pickup is moved to a track that corresponds to the address where the data to be read is stored and a correction processing unit performs a predetermined correction processing on the computed number of tracks to be traversed, taking into consideration the error data stored in the memory.

Abstract: A focus search method and a controller for a digital disk overcomes a shortcoming of a conventional focus search method in which a focus search on a specified layer is always performed from the same direction if a layer jump for changing a layer has been improperly performed during reproduction from a digital disk such as a DVD having a plurality of recording layers, thus taking much time for the focus search when the focus search is begun from a point away from a specified layer. A focus direction used for an immediately preceding focus search performed from an initial focus search position at the outer side of two recording layers is stored in a focus direction memory of a focus direction setter.
