The present invention provides an image monitoring device of an elevator car which can detect whether passengers are present in the car with high precision without being influenced by light irradiated from a window of a car door. Images captured by an imaging device (3) when no one is in a car (1) are used as basic images (1A), the basic images (1A) are divided into a plurality of areas including a ground portion area and left and right side wall surface areas, and brightness values of the divided areas are stored in a RAM (4d) in advance. Every time a door (2) of the car (1) is opened, the brightness value of the ground portion area (1A1) of the basic images (1A) is compared with the brightness value of a ground portion area (1B1) of an image (1B) captured by the imaging device (3) when the door is opened, if the difference of the two brightness values is large, the inside of the car (1) is determined to be influenced by irradiation of extraneous light, and information of the basic images (1A) stored in the
