    摘要: An audio processing system includes at least one first microphone, at least one adaptive filter, and a processor. The at least one first microphone acquires a first audio signal and outputs a first signal based on the first audio signal. The first audio signal includes at least one of a first audio component generated at a first position and a second audio component generated at a second position different from the first position. The first signal is input to the at least one adaptive filter. The at least one adaptive filter outputs a passing signal based on the first signal. The processor, when executing a program stored in a memory, performs: making a determination of which of the first audio component and the second audio component the first audio signal includes more; and controlling a filter coefficient of the adaptive filter based on a result of the determination.

    摘要: An image pickup apparatus in which three microphone units are arranged with high space efficiency. The image pickup apparatus comprises a lens barrel having an optical axis, a first microphone unit disposed to a left of the optical axis in a left-right direction when viewed from an optical axis direction, a second microphone unit disposed to a right of the optical axis in the left-right direction, and a third microphone unit disposed between the first microphone unit and the second microphone unit in the left-right direction, wherein when viewed from the optical axis direction, a lower end position of the first microphone unit and a lower end position of the second microphone unit are lower than an upper end position of the lens barrel and a lower end position of the third microphone unit is higher than the upper end position of the lens barrel.

    摘要: An image processing apparatus includes a first reception section, a second reception section, an association processing section, an object detection section, and a process execution section. The first reception section receives image information acquired by an image sensor. The second reception section receives sound information that is acquired by one or plural directional microphones and that is generated for at least a partial region in a field of the image sensor. The association processing section associates the sound information with a pixel address of the image information indicating a position in the field. The object detection section detects, from the image information, at least a part of an object that is present in the field. The process execution section executes a predetermined process on the object on the basis of a result of the association performed by the association processing section.

    摘要: Disclosed are techniques for an improved method for performing sound source localization (SSL) to determine a direction of arrival of an audible sound using a combination of timing information and amplitude information. For example, a device may decompose an observed sound field into directional components, then estimate a time-delay likelihood value and an energy-based likelihood value for each of the directional components. Using a combination of these likelihood values, the device can determine the direction of arrival corresponding to a maximum likelihood value. In some examples, the device may perform Acoustic Wave Decomposition processing to determine the directional components. In order to reduce a processing consumption associated with performing AWD processing, the device splits this process into two phases: a search phase that selects a subset of a device dictionary to reduce a complexity, and a decomposition phase that solves an optimization problem using the subset of the device dictionary.
