PROBLEM TO BE SOLVED: To provide an interphone device capable of adjusting exposure without capturing a plurality of images by using position information of the sun.SOLUTION: The interphone device comprises: an entrance slave unit including a camera for imaging a visitor, and a slave unit microphone and a slave unit speaker for communicating with a resident; and a living room master unit including a monitor for outputting video images imaged by the camera, and a master unit microphone and a master unit speaker for communicating with the visitor. When adjusting the exposure of the video images imaged by the camera, the entrance slave unit includes: a sunlight sensor part for determining whether or not sunlight is in a camera imaging range; a sun position detection part for detecting at what position in the camera imaging range the sunlight detected in the sunlight sensor part is; and a slave unit CPU for eliminating light quantity information of a range where the position information of the sun detected in the sun position detection part is calculated of the light quantity information acquired from the camera imaging range, and adjusting the exposure using the light quantity information of a range other than that. |
