Abstract: An image synthesizer for detecting an area photographs a processing object area having a predetermined hue from video data obtained through a video camera, inserts another image in the area, and then produces a synthesized image. The image synthesizer forms on the processing object area a light source image having the same hue as the processing object area, detects position information of the video camera with respect to the processing object area with the light source image as a reference, and changes the other image in correspondence with position change of the video camera with the position information as a reference. In this way, the position of the video camera is detected with the light source image as a reference, and image which is inserted is changed according to a position change of the video camera. Therefore, when the video camera is moved, an image which is inserted is also changed according to the movement, and consequently, an image with no feeling of physical disorder is obtainable.

Abstract: A data recording device for a motion picture film is provided in which one ends of plural optical fibers are connected to light emitting devices and the other ends of the optical fibers are arrayed in accordance with a dot pattern of audio data to be recorded. The light emitting diodes are turned on responsive to the audio data to be recorded on the motion picture film.

Consequently, the LEDs are affected to a lesser extent by heat evolved on turning on the LEDs. By linearly arraying the optical fibers at the head unit 1, a larger quantity of audio data may be recorded on the motion picture film.

Abstract: A tape guide device includes a guide member of a cylindrical configuration for guiding a tape, a ultrasonic vibrator secured to the guide member for vibrating the guide member in standing-waves configuration and a supporting member for supporting the guide member. A rotation preventing member for preventing a rotation of the guide member is formed on one of a pair of tape position restricting members in the width direction of the tape, whereby the number of the assembly parts of the tape guide device is reduced and a mechanism thereof is simplified. Therefore, the tape guide device can be miniaturized. Also, the structure and the shape of the ultrasonic vibrator are selected so that, even when the tape guide device is miniaturized, a coefficient of friction between the tape and the guide member becomes an optimum value.
