Abstract: In a drive device for driving an ultrasonic transmitter, a drive signal generating unit generates a drive signal for driving the ultrasonic transmitter, based on a base signal having a plurality of unit frequency signals arranged in a time series, corresponding to respective codes forming a code sequence. When a first unit frequency signal and a second unit frequency signal chronologically adjacent to it are switched in a discontinuously switching state that is different from a continuously switching state where the first and second unit frequency signals are switched such that a target frequency for a transmission frequency changes continuously at a substantially constant rate, the drive signal generating unit shifts the frequency in at least a switching portion immediately after start of the second unit frequency signal, in a same direction as a direction of frequency change from the first unit frequency signal to the second unit frequency signal.

Abstract: A vehicle perimeter monitor includes: a shooting device mounted on a vehicle for shooting an image of an outside of the vehicle; a controller including a detector and a generator, wherein the detector sets a detection line in a shot image, and detects a change amount of brightness of a picture cell on the detection line so that the detector detects movement of a moving object along with the detection line, and wherein the generator generates information display according to a detection result of the moving object; and a display for displaying the shot image and the information display.

Abstract: A lens barrel includes a cam ring that includes a first cam sliding part and a second cam sliding part, and that is rotated in a direction around an optical axis; a fixing and holding barrel in which the cam ring is disposed; a moving ring that includes a first cam engagement part and a second cam engagement part, and that is moved in an optical axis direction; and an optical element that is moved in connection with movement of the moving ring. In a part of a movement range of the moving ring, one of the first cam engagement part and the second cam engagement part is engaged with the first cam sliding part or the second cam sliding part, and another one of the first cam engagement part and the second cam engagement part is positioned on an outside of the cam ring in the optical axis direction.

Abstract: An image correction apparatus, an image correction method and a transformation map making method are disclosed. The apparatus includes an imaging device, a memory section, a corrected image creation section and a display device. The imaging device has an optical axis inclined upward or downward with respect to a ground surface, and captures an image. The corrected image creation section transforms the captured image into a corrected image in accordance with a transformation map stored in the memory section, thereby making a correction on inclination of a display object with respect to a vertical direction. The display device displays the corrected image.

Abstract: A vehicle surrounding monitoring device includes an image display control section and a guide line overlapping section. The image display control section makes a view image based on a shot image of a surrounding of a vehicle and displays the view image on a display device. The guide line overlapping section overlaps a guide line for assisting a forward parking of the vehicle on the view image. The guide line includes a front end guide line extending from a first position to a second position. The first position is a position obtained by rotationally transferring a position of a rotational outer front end of the vehicle by 90 degrees around a rotational center of the vehicle. The second position is located at a distance of a width of the vehicle from the first position toward a rear in a front-rear direction of the vehicle.
