  • Patent number: 11921971
    Abstract: A live broadcasting recording equipment, a live broadcasting recording system and a live broadcasting recording method are provided. The live broadcasting recording equipment includes a camera, a processing device, and a terminal device. The camera captures images to provide photographic data. The processing device executes background removal processing on the photographic data to generate a person image. The terminal device communicates with the processing device and has a display. The processing device executes multi-layer processing to fuse the person image, a three-dimensional virtual reality background image, an augmented reality object image, and a presentation image, and generate a composite image. After an application gateway of the processing device recognizes a login operation of the terminal device, the processing device outputs the composite image to the terminal device, so that the display of the terminal device displays the composite image.

  • Publication number: 20230206964
    Abstract: A plurality of bit lines corresponding to elements of an input vector intersect a plurality of word lines and a plurality of memristive cells are located at the intersections. At least three cells are grouped together to represent a single matrix element. At least three word lines correspond to each element of an output vector. An A/D converter is coupled to each of the word lines, and for each line, except a first, in each group, a shifter has an input coupled to one of the A/D converters. For each group, an addition-subtraction block adds the output of the A/D converter coupled to the first one of the word lines to outputs of each of the shifters except that for a last one of the word lines, subtracts the output of the last shifter, and outputs a corresponding element of an output vector.
