Abstract: To provide an image encoding device that can record desired hours of encoded data in a recording medium having a predetermined storage capacity, in a VBR encoding system. An image encoding device includes an image encoding unit that encodes a plurality of sequentially input images to generate a plurality of encoded data that configures video data, an average image complexity calculation unit that calculates average image complexity of complexity of the input images in a fluctuation cycle, based on the plurality of encoded data, and a code amount control unit that controls a code amount of the encoded data generated in the image encoding unit based on the average image complexity.

Abstract: A video transmission apparatus detects a target object to be monitored from images obtained by imaging a monitoring area, tracks the detected target object, obtains existence time from appearance to disappearance of the target object, and transmits a data volume reduced image of the target object to a video reception apparatus. The video reception apparatus analyzes the data volume reduced image transmitted from the video transmission apparatus and transmits a video request of the target object to the video transmission apparatus) based on input made according to the result of the analysis. When the video request transmitted from the video reception apparatus is received, the video transmission apparatus generates a monitoring video from the appearance to the disappearance of the target object based on the existence time of the target object and transmits the monitoring video to the video reception apparatus.
