摘要： An object of the present invention is to accurately detect a blank area (side mask) appearing outside an image area when an image has a different aspect ratio against a display screen. A boundary between a side mask and an image area is detected with a change of a luminance level of a plurality of scan lines of an image. The side mask is detected with a logical addition of detected results of an active detection unit 3a and a level detection unit 3b. The level detection units 3b sets previously a plurality of judge areas and detects the side mask when the judge areas set in the side mask do not change the mean luminance levels for a prescribed period of time and the judge areas set in the image area change the mean luminance levels.

摘要： A fire alarm system provided with a fire receiver (1) to which a plurality of fire sensors and controlled apparatuses are connected. The fire receiver (1) comprises a LAN interface (11) for connecting with other fire receivers. When a fire sensor issues an alarm, the fire receiver transmits the fire information over the LAN together with a group number set in advance, and displays (12) only the fire information of the same group number when the fire receiver receives fire information transmitted from the other fire receivers via the LAN. Thus, even is a plurality of fire receivers are used in a large building divided into ridge sections, fire information can be shared without causing disorder.
