Abstract: A gear shift control system controls an actuator so that a pushing force will be a constant gearing-phase pushing force, during a gearing phase. The gear shift control system performs control on the basis of the number of rotation of the engine in the gearing phase, which is measured at the start of the gearing phase, so that the constant gearing-phase pushing force will increase as a number of rotation of the engine in the gearing phase increases. Thus, the hitting sound due to collision between the sleeve and the shift gear in shifting gears is reduced.

Abstract: In an image correction method and an image capture device, a one-frame addition average calculation unit calculates a one-frame addition average value. If the one-frame addition average value falls within an appropriate range, a determination circuit inputs image data for one frame to an adder and the adder adds the image data to a cumulative correction value to update the correction value. The updated correction value is stored in a frame memory. If the one-frame addition average value is outside the appropriate range, the image data for one frame is discarded. After updating the cumulative correction value until the number of updates reaches a prescribed number, an FPN correction value is calculated by dividing the cumulative correction value stored in the frame memory by the prescribed number, and an image is corrected by subtracting the FPN correction value from the image data inputted at the time of imaging.
