| Abstract | To provide an intercom slave unit capable of controlling brightness of light emitting means for displaying a position of a call operation section by light emission without depending on an illuminance sensor by using information to be obtained from a camera.SOLUTION: An intercom slave unit includes: a camera 11; an LED 16 for facilitating recognition of a position of a call operation section to call a resident; and an LED control section 17 for changing brightness of the LED 16. The LED control section 17 obtains a gain signal from the camera 11, calculates luminance from the gain signal, and controls brightness of the LED 16 by calculated luminance information.SELECTED DRAWING: Figure 1
【課題】 カメラから得る情報を用いることで、照度センサに頼らず呼出操作部の位置を発光表示する発光手段の明るさを制御できるインターホン子機を提供する。【解決手段】 カメラ１１と、居住者を呼び出すための呼出操作部の位置を認識し易くするためのＬＥＤ１６と、ＬＥＤ１６の明るさを変更するＬＥＤ制御部１７とを有し、ＬＥＤ制御部１７は、カメラ１１からゲイン信号を入手して、ゲイン信号から輝度を算出して、算出した輝度情報によりＬＥＤ１６の明るさを制御する。【選択図】 図１ |
