The invention provides an image collecting device, an image collecting method and a refrigerator. The image collecting device comprises an image collecting module which is used for collecting images of objects in a refrigerator storeroom; a storage module which is used for storing the images collected by the image collecting module; a sensor module which is used for collecting an opening process of a refrigerator door or an opening angle in the opening process; a control module which is used for controlling the image collecting module to collect the image while the opening angle collected by the sensor module is in a preset angle range; a communication module, which is used for transmitting the images stored in the storage module to a user terminal, wherein the image collecting module is arranged at a preset position located at the inner side of the refrigerator door. The image collecting device of the invention could obtain the images of relative large coverage by using less image collecting equipment.
