The present invention discloses a single microphone hearing aid noise reduction method. The method comprises: acquiring an original sound signal, identifying the noise characteristics of noise in the original sound signal; iteratively training the noise reduction formula obtained by noise identification, optimizing the noise reduction formula, and acquiring the optimal values of parameters in the noise reduction formula; calculating the original sound signal according to the noise reduction formula optimized by iterative training and the specific value of each parameter, and outputting the signal to noise ratio of the noise; and judging whether the signal to noise ratio is qualified, and if qualified, carrying out hearing aid processing of the processed sound signal. The present invention can quickly identify, suppress and converge unsteady noise by single microphone noise reduction without the aid of special iterative adaptive learning filter hardware built in a hearing aid chip.

The invention discloses a method for realizing hearing aid function based on Bluetooth headset chip and a Bluetooth headset: the common Bluetooth headset chip software of Bluetooth headset is upgraded to a specific Bluetooth headset chip with hearing aid function by a hearing loss correction software; a hearing aid algorithm module is embedded into the development kit of the common Bluetooth headset chip in the form of software library by the hearing loss correction software, so that the common Bluetooth headset chip has the hearing aid function only by software upgrade; after being processed by the hearing aid algorithm module, a sound signal is output to a hearing-impaired user, so that the hearing-impaired user can use the common Bluetooth headset to realize the hearing aid function. For the Bluetooth headset, a special hearing aid chip does not need to be installed or any change does not need to be made to the headset hardwares, and the function and price can meet the needs of hearing-impaired users, so that the hearing impaired users can enjoy great convenience from such a Bluetooth headset without buying expensive special hearing aid.

The present invention provides a method for adjusting stereoscopic image parallax. An original camera is provided. A scene space corresponding to the original camera is preset, including presetting a depth range of the scene space. Preset viewing environment parameters for displaying stereoscopic images of a scene in the scene space are configured, including presetting a depth range of an actual view space. The method further includes establishing a mapping relationship between the depth range of the actual view space and the depth range of the scene space. According to the mapping relationship, the preset viewing environment parameters and the scene space, camera parameters for adjusting stereoscopic image parallax are calculated. The original camera is adjusted based on the camera parameters to capture the scene. Thus, the stereoscopic images of the scene can be generated and presented.
