  • Publication number: 20200196990
    Abstract: An ultrasonic imaging device includes an ultrasonic generating unit and an ultrasonic imaging processing unit. The ultrasonic generating unit repeatedly turns on N of M ultrasonic array elements of the ultrasonic probe multiple times as a group of array elements for linear scanning, and each scan is to emit an ultrasonic signal by each group of array elements and receive an echo signal of the ultrasonic signal. The ultrasonic imaging processing unit extracts a central echo signal from the echo signal in each scan to form a channel signal, and according to the arrival time of the echo signals, each central echo signal in the channel signal is delayed and summed to generate a modified channel signal. The modified channel signal is subjected to image synthesis process to obtain an ultrasonic image.

  • Patent number: 10048360
    Abstract: An ultrasound imaging system includes a beam receiving circuit and a back-end circuit. The beam receiving circuit receives a plurality of digitized echo signals. The back-end circuit is coupled to the beam receiving circuit for outputting a plurality of compressed delay timing parameters corresponding to a plurality of channels to the beam receiving circuit. The beam receiving circuit decompresses the compressed delay timing parameters into a plurality of delay timing parameters, and processes the digitized echo signals into an ultrasound beamforming value according to the delay timing parameters corresponding to the channels. The back-end circuit synthesizes an ultrasound image according to the ultrasound beamforming value outputted from the beam receiving circuit.

  • Patent number: 9449597
    Abstract: An ultrasound receiving method is provided. N return-wave signals corresponding to N channels are respectively stored in N set of shift register arrays. Each set includes a delay filter unit and M shift registers. A delay controller is utilized to assign a set of coefficients to the delay filter unit to perform an interpolation operation on data of the M shift registers to obtain an output value. The delay controller is utilized to decide delay time of each channel according to a delay table, and accordingly to control a time multiplexer to switch and output the N output values in order. A multiplier is utilized to multiply the output value received from the time multiplexer by a weighted value corresponding to the channel to obtain a corrected value. An accumulator is utilized to accumulate the N corrected values to obtain an image value.

  • Patent number: 8966402
    Abstract: A system and method are provided to edit interactive three-dimensional multimedia. A user interface of the system is provided with an event level template that includes event series levels with multiple event developing points. Through the user interface, multiple interactive events related to a first character of the event developing point are edited. Through a three-dimensional engine, interactive relevances are built up between interactive events and multiple materials inside one or more database. When the interactive three-dimensional multimedia with multiple materials is output, the interactive events corresponding to the event developing points are performed according to a user command. An online editing and exchanging method integrated with the system and method is also provided to share pre-edited templates on an exchange server; each of the pre-edited templates is extracted from an interactive three-dimensional multimedia pre-edited by the system and method.

  • Patent number: 7620198
    Abstract: A watermark coding method and its recording medium utilize image interleaving and wavelet-based transformation to enhance the robustness of the image. The watermark series to be inserted is converted, encrypted, and modulated to increase the difficulty in decoding and restoring. Finally, the watermark is distributed and hidden in various frequency bands of the image in a frequency hopping way, generating a robust watermarked image. When used in a recording medium, side information produced during coding is recorded in the lead-in area of the recording medium to reduce the chances of illegal copying.

  • Publication number: 20080140988
    Abstract: A method for reducing memory resource utilization is disclosed, applied to simplify address space of a table. Values stored in address fields of an original table are analyzed to determine whether logical relationship is detected between the values. If the logical relationship is detected, the values stored in the original table are classified to multiple base values and corresponding reduced values to generate a transformation table. Values with the same logical relationship for base values and the corresponding reduced values are stored in a new and equivalent address field of a reduction table.
