In cleaning using a self-propelled cleaning device, firstly the cleaning device moves alongside a wall surface and then a reference direction is set. Next, the cleaning device advances alongside the wall surface at a prescribed distance, makes a right-angle turn, and travels in the reference direction. When the cleaning device reaches the surface of an opposing wall, it moves in a spiraling manner. At that time, the orientation angle of the cleaning device, which is estimated using a gyro sensor, is checked and corrected. If an obstacle is encountered while traveling, the cleaning device travels on a path that avoids the obstacle or travels in a spiral manner in a region in front of the obstacle.

In an image display apparatus of the invention, a signal input unit outputs a complex image signal, which has been converted to an easily-processed format, to a signal-for-display generator. The signal-for-display generator converts the complex image signal to a signal suitable for displaying at a display unit. An apparatus state-detector detects a state of the display apparatus. Based on apparatus state information input from the apparatus state-detector, an arithmetic unit calculates an amount of non-uniformity to be corrected, and outputs it to a non-uniformity corrector. Based on the non-uniformity correction amount corresponding to a position displayed at the display unit, the non-uniformity corrector corrects the image signal input from the signal-for-display generator, converts it to a signal format that can be used at the display unit, and outputs it.

A self-propelled cleaning device having a cylindrical side cover has a suction body capable of moving transversely to the forward direction. The side cover is held by a base via a suspension. When cleaning corners of a room, the suction body moves by a wall and as the suction body moves to a corner, the movement amount of the suction body is changed. When an obstacle touches the cleaning device, the side cover moves, and the article touches a side cover switch, and the direction of the article is detected.

A self-running vacuum cleaner comprises a homing mode of following a back of a user with receiving a signal from a light emitting means or a transmitting means of a position indicator means held by the user, an instruction operation mode, in which the user instructs a cleaning area to the self-running vacuum cleaner, and an execution mode for cleaning up the cleaning area instructed. When the self-running vacuum cleaner operates under the homing mode or the instruction mode, a signal from the light-emitting means or the transmitting means is received by a receiver means attached on a periphery portion of a measuring means, which is provided in an upper portion of the vacuum cleaner. Comparing the signals from the two (2) receiver means in strength thereof determines the distance and the direction from the position indicated by the light-emitting means or the transmitting means up to the vacuum cleaner.
