Abstract: An image recovery method is applied to a video management server remotely connected with a plurality of camera devices to receive a resupply image stored by each camera device while being disconnected from network. The image recovery method includes: the video management server establishing a resupply list corresponding to resupply images of the camera devices while the camera devices are recovered from a disconnection state to a connection state, then determining whether to actuate a resupply process and executing a resupply connection to receive at least one of the resupply images while the resupply process is actuated, and comparing a bandwidth usage quantity of the resupply connection with a threshold to adjust a transmission velocity of the resupply connection in accordance with a comparison result.

Abstract: An image processor and a fisheye image display method thereof are provided, where the fisheye image display method performs the following steps. A fisheye image and part images are received, and each part image and the fisheye image have a relation therebetween. A frame layout with at least one cell is read. The fisheye image or part image is inserted in the cell. The frame layout is set as an output image. A modification command is received. A modification procedure is performed to modify the output image according to the modification command. Each part image and the fisheye image maintains the relation after the output image is modified.
