  • Patent number: 9977651
    Abstract: The present disclosure discloses an image processing method of a mobile terminal, and a mobile terminal. To process an image, an audio signal is collected using a sensor of the mobile terminal. Air-blowing signal intensity is acquired by performing a windowed fast Fourier transform (FFT) on the audio signal to obtain a frequency domain signal of the audio signal. The frequency domain signal of the audio signal is divided into at least one time-slice frequency domain signal. It is then identified whether the audio signal is an air-blowing signal according to the at least one time-slice frequency domain signal and a preset property of the air-blowing signal. The air-blowing signal intensity is acquired according to the at least one time-slice frequency domain signal when the audio signal is identified as an air-blowing signal. An image is acquired according to the air-blowing signal intensity.

  • Publication number: 20170154038
    Abstract: The present invention discloses a method and a device for managing pictures of a mobile terminal, where a log file is set on the mobile terminal to record picture file information and/or picture file storage directory information. The method includes: monitoring, by the mobile terminal, changes of picture files and changes of a storage directory of the picture files, and updating the log file according to the detected changes if any change of the picture files or change of the storage directory of the picture files is detected; and providing, by the mobile terminal, the log file to other terminal device when the mobile terminal is connected to the other terminal device so that the other terminal device manages the picture files on the mobile terminal according to the log file.

  • Publication number: 20140198118
    Abstract: An image browsing method, system and computer storage media are disclosed. The method includes: obtaining a user's operation request for an image; comparing the operation request with a preset condition, and determining whether to cache the image into a main cache. When it is required to cache the image into the main cache, further determining whether it is the first time that the image is rendered; if yes, employing a main thread to cache the image into the main cache, to obtain the image from the main cache, and to render the image. Otherwise, employing a main thread to obtain an image adapted to the capacity of the main cache from an image chain, and to render the image; and displaying the image rendered. This avoids unsmooth browsing of the image due to time-consuming creation of the images to be rendered, thereby allowing smooth image browsing.
