Driving-operation assist and recording medium

A vehicle-operation assist for a vehicle mounted with a camera, comprising:

• an operation-start detecting unit operable to detect that an actual driving operation corresponding to a predetermined driving operation is started, automatically or through an input from a driver;
• a circumferential-state imaging unit operable to generate a circumferential-state image using an output image from the camera, wherein the circumferential-state imaging unit changes a way of generating the circumferential-state image when the actual driving operation is started;
• a synthetic-image generating unit operable to generate a synthetic image by using the circumferential-state image, said synthetic image including an assumed-movement pattern showing movement of the vehicle in case of performing the predetermined driving operation, said assumed-movement pattern including (i) a trace between a start position of the vehicle and an end position of the vehicle, and (ii) a synthetic image of the vehicle at the end position in case of performing the predetermined driving operation;
• and
• a display unit operable to display the synthetic image,
• wherein the synthetic-image generating unit generates a synthetic image of which a positional relationship between the assumed-movement pattern and the circumferential-state image is fixed while an actual driving operation corresponding to the predetermined driving operation is performed by following said trace between said start position and said end position.
