[0031] First, a recording device for collecting sound signals through multiple channels and recording the sound signals on a recording medium will be described.

[0032] figure 1 A configuration diagram of a recording device and peripheral devices related to the first embodiment of the present invention is shown.

[0033] figure 1 The recording device 10 shown in includes a function of collecting and recording multi-channel sound signals and a function of receiving and recording sound signals wirelessly collected and transmitted by the wireless microphone device 20 . In addition, in the following description, the sound signal collected by the wireless microphone device 20 is referred to as a wireless sound signal.

[0034] In the recording device 10 , the multi-channel sound processing unit 11 converts the sound signals collected by the plurality of microphones 11 a to 11 d into digital signals, respectively, and outputs the digital signals to the multi-channel sound synth...

[0046] Next, a video camera for recording multi-channel sound signals and picked-up image signals on a recording medium will be described.

[0047] figure 2 An example using a video camera related to the second embodiment of the present invention is shown.

[0048] The target individual 1 carries the wireless microphone device 20 . In addition, the wireless sound signal transmitted from the wireless microphone device 20 is received by the camera 30 of the photographer 2 and synthesized into a multi-channel sound signal collected by the microphone of the camera 30, and the synthesized sound signal is recorded. For this reason, when the individual 1 is separated from the photographer, although the image is picked up and the sound signal is collected when the surrounding sound is louder than the voice of the individual 1, the voice of the individual 1 can be clearly heard at the time of reproduction.

[0082] Next, a video camera that records a multi-channel sound signal on a recording medium together with a picked-up image signal, which is different from the second embodiment, will be described. In the camera related to the third embodiment, the basic configuration is similar to that in the second embodiment. The multi-channel sound processing unit 35 outputs a plurality of directional sound signals, and the multi-channel sound synthesis unit 37 changes distribution of the sound signals to output channels, or changes a synthesis ratio according to a zoom factor. In addition, the distribution or combination ratio of the sound signal (wireless sound signal) from the wireless microphone device 20 is changed according to the zoom factor. Through these operations, it is possible to record sound with a high live feeling through the zoom operation.

[0083] Figure 8 The direction of the sound signal generated by the multi-channel sound processing unit is shown.

Abstract

The invention provides an imaging device that collects sound, takes images, and records the sound and images on a recording medium, including: a sound collection unit for collecting multi-channel sound signals; a wireless communication unit for wirelessly receiving a sound signal sent from the external sound collection device; and a sound synthesis unit for synthesizing the sound signal received by the wireless communication unit into at least any one channel of the sound signal collected by the sound collection unit.

Description

technical field [0001] The present invention relates to an imaging device for collecting sound and picking up images and recording the images and sounds on a recording medium, as well as a recording device and method for recording the collected sound signals, in particular to a multi-channel collection And an imaging device and a sound recording device and method for recording an audio signal. Background technique [0002] Video cameras with imaging functions and sound collection functions as well as image and sound recording functions are well known in the prior art. In such a video camera, except when a mono signal is recorded and reproduced, sound signals of two channels including a left channel and a right channel are generally recorded and reproduced. According to this method, since the sound signal can be clearly recorded even if the position of the sound source in the horizontal direction on the imaging side of the camera changes at the time of reproduction, a change...
