  • Method and device for image zoom out processing
    Patent number: 9659347
    Abstract: A method for image zoom out processing includes: determining whether a predetermined zoom out ratio is smaller than a first predetermined threshold; when the predetermined zoom out ratio is smaller than the first predetermined threshold, performing a zoom out process on an image according to the first predetermined threshold by a bilinear interpolation algorithm to obtain a zoomed out image; determining whether a product of a resolution of the zoomed out image and the first predetermined threshold is greater than or equal to a target resolution; when the product is greater than the target resolution, repeating the step of performing the zoom out process; when the product is smaller than the target resolution, performing the zoom out process on the image according to a second predetermined threshold by the bilinear interpolation algorithm so that the resolution of the zoomed out image reaches the target resolution.

  • Method and device for detecting primary synchronization signal
    Patent number: 9444610
    Abstract: A method for detecting a primary synchronization is provided. The method includes: obtaining a time-domain signal sequence for synchronization; obtaining a correlation result corresponding to the time-domain signal sequence; normalizing the correlation result according to a received signal strength indicator corresponding to the time-domain signals; and sorting the normalized correlation result to ascertain a peak value position corresponding to the correlation result.
