Abstract: An image processing method and apparatus in a virtual reality device are provided. The method includes determining, according to a visual acuity status of a user of a virtual reality device, a filtering parameter corresponding to visual acuity of the user. For an image played on the virtual reality device, an inverse filtering processing is performed on the image according to the determined filtering parameter. An image obtained after the inverse filtering processing is then displayed on a screen of the virtual reality device. Embodiments of the present invention also provide a device and a terminal for such image processing.

Abstract: A method and an apparatus for controlling a running status of a wearable electronic device, where the method includes determining a posture of a wearable electronic device, where the posture includes a stationary posture and a moving posture, and controlling a running status of the wearable electronic device according to the posture. According to the method and the apparatus for controlling a running status of a wearable electronic device, the posture of the wearable electronic device is monitored using, for example, a gyroscope signal from a mobile phone, whether a user is using the wearable electronic device is determined, and the running status of the wearable electronic device is determined without using a light sensor, which reduces manufacturing costs of the wearable electronic device.

Abstract: An image processing method and apparatus in a virtual reality device are provided, to resolve a low precision problem that is caused because existing VR glasses are adjusted by moving a lens to adapt to users with different myopic degrees. The method includes: determining, according to a visual acuity status of a user of a virtual reality device, a filtering parameter corresponding to visual acuity of the user; and for an image played on the virtual reality device, performing inverse filtering processing on the image according to the determined filtering parameter; and displaying, on a screen of the virtual reality device, an image obtained after the inverse filtering processing. Embodiments of the present invention also provide a device and a terminal for such image processing.

Abstract: A method for recording in a video chat, and a terminal to reduce background noise and noise of multiple persons in a video chat process, and improve voice quality of a video chat. A first terminal divides a video calling screen into multiple angular domains. After beam configuration information of each angular domain is determined, beam configuration information of a target angular domain of the first terminal is sent to a second terminal. The second terminal performs, according to the beam configuration information, beamforming processing on an audio signal obtained through recording such that signal strength of an audio signal of the target angular domain is enhanced, and signal strength of an audio signal of another angular domain is attenuated.

Abstract: Embodiments of the present disclosure disclose a method for recording sound of a video-recorded object and a mobile terminal, so as to reduce background noise in recorded sound of a video-recorded object, and improve quality of the recorded sound. The method in the embodiments of the present disclosure includes: obtaining, by a mobile terminal by means of facial recognition, position information of the video-recorded object; and performing processing on recorded sound signals, so as to enhance signal intensity of a sound signal at a position of the video-recorded object, and attenuate signal intensity of a sound signal at another position, to obtain sound at the position of the video-recorded object.

Abstract: A method and an apparatus can be used for identifying a posture. The method includes obtaining information about sending an ultrasonic wave by one or more ultrasonic transmitters and obtaining information about receiving the ultrasonic wave by ultrasonic receivers. The one or more ultrasonic transmitters are fixed on an object to be identified. The number of the one or more ultrasonic transmitters is at least one and the number of the ultrasonic receivers is at least three. A posture of the object to be identified can be identified according to the obtained information about sending an ultrasonic wave by one or more ultrasonic transmitters and information about receiving the ultrasonic wave by ultrasonic receivers.
