    Abstract: An analysis method and an electronic apparatus for breast image are provided. The method includes the following steps. One or more breast ultrasound images are obtained. The breast ultrasound images are used for forming a three-dimensional (3D) breast model. A volume of interest (VOI) in the breast ultrasound image is obtained by applying a detection model on the 3D breast model. The VOI is compared with a tissue segmentation result. The VOI is determined as a false positive according to a compared result between the VOI and the tissue segmentation result. The compared result includes that the VOI is located at a glandular tissue based on the tissue segmentation result. In response to the VOI being located in the glandular tissue of the tissue segmentation result, the VOI is compared with the lactiferous duct in the 3D breast model.

    Abstract: A data driving circuit proofed against excessive pixel brightness because of overvoltage on the data line comprises a shift register circuit, a first latch circuit, a second latch circuit, a level shift circuit, a DAC circuit, and an output circuit. The second latch circuit detects a change in the MSB of the data signal of a sampled signal, and outputs a signal for applying a pre-operation of the current data line. When the MSB of the sampled signal is changed, the second latch circuit outputs a pre-operation enabling signal, and whether the grayscale value of the current data line is within a specified region. If within the specified region, the second latch circuit outputs an invalid signal, and the pre-operation is disabled.
