Embodiment Construction

[0025] figure 1 An example of the configuration of an imaging system and a recording system related to an embodiment of the present invention is shown.

[0026] The imaging processing apparatus 1 has an imaging function, and records video signals and multi-channel (for example, 4-channel) audio signals obtained by image capturing on a predetermined recording medium (disc recording medium such as a digital versatile disc (DVD) ; and functions on tape recording media such as magnetic tape). Types of the imaging processing device 1 include, for example, camcorders, computers each having a camera function, personal digital assistants (PDAs), various video devices.

[0027] The camera system included in the imaging processing apparatus 1 includes a variable magnification optical system 2 including a zoom lens, an imaging unit 3 using a solid-state imaging element such as a CCD or a C-MOS area image sensor, a picture tube, and the like. The imaging processor 4 sends and processes ...

Abstract

An information processing apparatus has a function of processing plural-channel audio signals associated with a video signal. The information processing apparatus includes an audio converting unit for generating a plurality of audio signals by converting the levels of the plural-channel audio signals in accordance with an adjusting parameter defined depending on information of image-capturing conditions concerning the video signal.

Description

[0001] Cross References to Related Applications [0002] The present application contains subject matter related to Japanese Patent Application JP2004-124450 filed in the Japan Patent Office on Apr. 20, 2004, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a technology in which effective reproduction of a sense of presence is achieved when sound of a plurality of channels is converted to generate surround sound by reflecting information on audio conversion such as zoom information in video recording mode audio conversion processing. Background technique [0004] Devices that can simultaneously record audio signals and video signals of multiple channels on a single recording medium, or that can play back recorded audio and video signals, such as camcorders, are known. [0005] When only stereo (2-channel) sound can be recorded or played back for a video signal acquired by video recording, it is diffic...
