Abstract: The problem when the use range of images for use in intra-prediction is expanded is that the requirement for line buffer size increases depending on the range of expansion, and, in order to solve this problem, the use range of imaged for use in intra-prediction is adaptively controlled. The intra-prediction apparatus 100 of the present invention has, a control section 115 that controls, based on the relationship between the position of a candidate image for use in intra-prediction for a block to be processed and the position of the unit where the block to be processed belongs, the partial range for use for intra-prediction beyond the end portion of the unit in a predetermined direction in the use range of the image for use for intra-prediction to be equal to or less than a predetermined maximum range.

Abstract: The disclosure is inputting a first image obtained by capturing an object of authentication moving in a specific direction; inputting a second image at least for one eye obtained by capturing a right eye or a left eye of the object; determining whether the second image is of the left eye or the right eye of the object, based on information including the first image, and outputting a determination result associated with the second image as left/right information; comparing characteristic information relevant to the left/right information, the characteristic information being acquired from a memory that stores the characteristic information of a right eye and a left eye pertaining to object to be authenticated, with characteristic information associated with the left/right information, and calculating a verification score; and authenticating the object captured in the first image and the second image, based on the verification score, and outputting an authentication result.
