摘要： A shutter operation state monitoring method performed in a thermal imaging camera includes, controlling a shutter of the thermal imaging camera to be closed, capturing a first thermal image, calculating a correction offset value for the first thermal image, controlling the shutter to be opened, capturing a second thermal image, applying the correction offset value to the second thermal image, measuring a sound with a microphone when controlling the shutter to be closed and/or when controlling the shutter to be opened, determining whether the measured sound matches an operation sound of the shutter, and outputting an alarm indicating malfunction of the shutter if the measured sound does not match the operation sound.

摘要： A door lock control device comprises: a door lock interface for communicating with a door lock; an imaging device; a controller for processing images to be acquired through the imaging device; and a storage medium. The controller determines each of first and second objects in the images as being either authorized or unauthorized depending on whether each of the first and second objects matches authentication data read from the storage medium, and controls the door lock through a door lock interface by referring to a distance between the first and second objects determined from the images when the first object is determined as being authorized and the second object is determined as being unauthorized.
