An RGB format adjustment method includes: obtaining subpixel values having interleaved positions from four pixels in unadjusted RGB format; obtaining subpixel values of a first pixel in an adjusted RGB format according to the obtained subpixel values, wherein the R subpixel value of the adjusted first pixel is equal to an R subpixel value of the unadjusted first pixel, the G subpixel value of the adjusted first pixel is equal to an R subpixel value of a fourth pixel in the unadjusted RGB format, and the B subpixel value of the adjusted first pixel is equal to a B subpixel value of the unadjusted first pixel; and obtaining R subpixel values, G subpixel values and B subpixel values of a second pixel, a third pixel and the fourth pixel according to the obtained subpixel values and the obtained R, G and B subpixel values of the adjusted first pixel.

RGB format adjustment and reconstruction method and circuit for depth frame packing and depacking

AC motor driving system and driving method thereof are provided. The driving system and method are capable of increasing power factor, adjusting waveform of the DC ripple voltage for increasing driving efficiency. The driving system is basically constructed by connecting three circuits. The first circuit is a three-phase full wave rectifying circuit and is used to transfer commercial electricity to a first DC voltage. Then, the second circuit is used to transfer the first DC voltage to a second DC voltage that ripples voltage thereof having a semi-sinusoidal waveform. The third circuit is an AC driving circuit, and receives the second AC voltage for driving the AC motor. Thereby, the driving efficiency can be increased. The capacitance used in the present disclosure has low capacitance value, thus the power factor can be increased, and usage time of the AC motor driving apparatus can also be increased.
