Abstract: An image processing device includes: first to third address registers that store three addresses, respectively, the three addresses indicating three bank regions, respectively; an input image bank managing unit that, when the image processing device receives an image from an imaging device, switches, between the first address register and the second address register, and sets a flag and supplies the address stored in the first address register as an address for writing the received image; an imaging processing unit that performs image processing on the received image; and an image processing bank managing unit that, when the flag is in a set state and the processed image is switched to another image to be processed, switches, between the second address register and the third address register, resets the flag and supplies to the image processing unit the address stored in the third address register.

Abstract: This invention is to provide a technique for properly correcting video metadata related to and synchronized with the video. This video metadata correction apparatus includes: a section identification unit that identifies a section including incorrect video metadata based on information concerning video metadata in a first video metadata storage for storing the information concerning the video metadata as sensor information synchronized with video and a first video feature value, which correlates with the information concerning the video metadata and is extracted from the video; and a corrector that corrects the video metadata in the identified section based on the first video feature value or a second video feature value, which correlates with the information concerning the video metadata and is extracted from the video. In this manner, only an incorrectly measured part can be corrected in an effective manner.

Abstract: An image synthesis apparatus includes an image obtainer obtaining a plurality of images taken by a plurality of cameras; a pixel value corrector which, with respect to each of the images, calculates a correction factor of an average pixel value in overlap regions located at the both ends of an image and, in the adjacent direction of the images, calculates the correction factor of a pixel value in a region other than the overlap regions by a predetermined continuous function connecting the correction factors in the overlap regions and corrects the entire image based on the calculated correction factor; a synthetic image generator synthesizing the images corrected by the pixel value corrector to generate one synthetic image; and an image output outputting the synthetic image to an external apparatus.

Abstract: A calculating unit of an integration server calculates an optimal processing sharing ratio for image format conversion processing between the integration server and each of a plurality of video accumulation servers. A processing unit of the integration server and each of the video accumulation servers perform image format conversion processing in a distributed manner based on the processing sharing ratio. An integrating unit of the integration server integrates the multimedia data subjected to the conversion processing by each of the video accumulation servers and the multimedia data subjected to the conversion processing by the processing unit.
