Abstract: To provide a system, a method and the like for acquiring more images or more quickly focused images. A control device acquires information regarding a situation of a range captured by an imaging device, determines a mode according to an assumed situation of the range captured by the imaging device among a plurality of focusing modes, and transmits designation information specifying the determined mode to the imaging device. The imaging device receives the designation information from the control device, and captures an image using the mode specified by the received designation information.

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.
