Abstract: The present invention provides a brightness adjustment method for multi-camera mosaicing, a computer-readable storage medium and a portable terminal. The method comprises: acquiring original images photographed respectively by six cameras and corresponding six groups of overlapping region images thereof; mapping the original image photographed by each camera with a brightness mapping function, and calculating the total brightness error of the brightness of the six groups of overlapping region images; adjusting the brightness mapping function of each camera respectively to minimize the total brightness error; adjusting an optimal brightness mapping function and performing mapping for panoramic mosaicing to generate a dark panoramic mosaic image with a dark part being the brightest and a bright panoramic mosaic image with a bright part being the darkest respectively; and fusing the dark panoramic mosaic image and the bright panoramic mosaic image to generate a panoramic mosaic image. By means of the technical solution of the present invention, a brightness mapping function for a camera with independent exposure is adjusted, such that a brightness difference between overlapping regions is eliminated, and the details in light and dark parts of an image also can be kept unchanged, thereby better improving the visual effect of a panoramic image.

Title: Power conversion system
Inventor: TSURUMA YOSHINORI
IPC: H02M7/797
Filed: 2019-05-29
Abstract: The power conversion system includes a power conversion circuit, a power conversion control circuit including a charging control mode, and a command value generating part. The charging control mode is a mode in which the output voltage of the power conversion circuit is controlled so that an interconnection inductance receives an interconnection inductance voltage determined by the power supply voltage vector of the AC power supply and the voltage command value vector having a delay phase with respect to the power supply voltage vector and having a magnitude and a phase based on the command value. 
     The command value generating part generates a first command value for operation of the charging control mode when the voltage of the storage battery is not lower than an over-discharge threshold. A second command value is generated for operation of the charging control mode when the voltage of the storage battery falls below the over-discharge threshold. The first command value causes the power conversion circuit to output an output voltage corresponding to the first voltage command value vector having a first magnitude and a first delay phase. The second command value causes the power conversion circuit to output an output voltage corresponding to a second voltage command value vector having a second magnitude smaller than the first magnitude.
