An image processing apparatus includes an image synthesizer configured to correct input images based on first-correction data to generate corrected images, and to generate a synthesized image by stitching the corrected images together, a determiner configured to determine whether the corrected images are appropriately stitched together in the synthesized image by using a first-trained model learned whether images are appropriately stitched together, a second-correction-data generator configured to generate second-correction data by supplying the input images to a second-trained model learned relationships between correction data used to correct source images to generate corrected images appropriately stitched together and the source images, and an image updater configured to output the synthesized image when a determination result of the determiner is affirmative and output an updated synthesized image generated by causing the image synthesizer to update the synthesized image based on the second-correction data when the determination result of the determiner is negative.

A wireless resource assigning apparatus for assigning wireless resources to transmission data of a plurality of users is disclosed. The wireless resource assigning apparatus includes a scheduling part configured to start scheduling for all users from a first wireless resource among a plurality of wireless resources prioritized according to a predetermined criterion, and repeat scheduling up to the last wireless resource for users except for users to whom any wireless resource has been assigned.

Wireless resource assigning apparatus and wireless resource assigning method

To provide a radio communication control apparatus and a radio communication control method capable of controlling simultaneous transmission and reception so as not to degrade system throughput. A simultaneous transmission and reception controllerdetermines whether the simultaneous transmission and reception using the same frequency are possible, based on radio spectrum environment information of an opposite party of communication and radio spectrum environment information of a self-apparatus. When the simultaneous transmission and reception using the same frequency are determined to be possible, a control signal transmission sectiontransmits instruction information, indicating that the simultaneous transmission and reception are possible, and a transmission parameter thereof, to the above communication terminal. After the transmission parameter is set, a communication sectionexecutes simultaneous transmission and reception with the above communication terminal using the same frequency, when the simultaneous transmission and reception using the same frequency are determined to be possible.
