More Information
Summary:An in-vehicle apparatus includes an FM radio tuner that receives FM broadcast waves of a reception frequency that is set; a FM radio controller; an LCD unit that is capable of changing a horizontal synchronous frequency corresponding to each horizontal line by varying a horizontal blanking period along the horizontal direction, without changing the numbers of effective pixels in horizontal display and vertical display, and an effective display period; a horizontal synchronous frequency setter that sets the horizontal synchronous frequency so that a minimum value of the differences between the reception frequency of the FM broadcast waves and multiplied frequencies that are integral multiples of the horizontal synchronous frequency is higher than or equal to a certain value; and a video processor that generates a video signal necessary to display at least one of a working screen and an operation screen in the LCD unit.
