An output stage circuit of a power conversion circuit includes a first power switch, a driving circuit, a first current source, a second current source and a combining circuit. The first power switch is coupled to a second terminal of a bootstrap capacitor. The driving circuit is coupled to the first terminal of the bootstrap capacitor and the first power switch and provides a control signal to the first power switch. The first current source generates a first current according to the control signal. The second current source generates a second current according to a reference voltage which is a first voltage at the first terminal or a second voltage at the second terminal. The combining circuit, coupled to the driving circuit, the first current source and the second current source, generates a switch operation indicating signal to the driving circuit according to the first current and second current.

Output stage circuit of power conversion circuit

A processing method for a pair of stereo images is provided. The method includes: extracting a pair of edge images from the stereo images, each edge image having edge pixels, each edge pixel of one of the edge images being associated with an overlap record and a disparity record; providing a plurality of image lateral shifts to sequentially determine a plurality of overlap levels between the pair of edge images; and updating the overlap record and the disparity record associated with a selected edge pixel to a maximum overlap level and a most-likely disparity, respectively. The maximum overlap level is a maximum among a plurality of associated overlap levels to which the selected edge pixel contributes. The most-likely disparity corresponds to the maximum overlap level.
