  • Patent number: 10210622
    Abstract: An image processing device, a method for processing an image, and a recording medium storing a program for causing a computer to execute the method. The image processing device and the method includes converting captured images in which image capturing ranges partially overlap into images in a coordinate system different from a coordinate system, based on a first conversion data, detecting an amount of misalignment in an overlapping area, calculating correction amounts for the first conversion data related to generation of the second conversion image for each coordinate value of the second conversion image, based on the detected amount of misalignment, detecting a subject area in which a subject exists from the second conversion image, and correcting the first conversion data related to generation of the second conversion image, using one of the calculated correction amounts of a subject area in which a dynamic subject exists.

  • Patent number: 9917972
    Abstract: An image processor executing a predetermined image process on an input image including a plurality of pixels to generate an output image includes an image-processing unit reading the input image required for generating the output image into an internal storing circuit as a reference image to execute an image process, a storing capacity determination unit determining whether or not a data size of the reference image is within a storing capacity range of the internal storing circuit, and a reference image division unit dividing the data size of the reference image when the data size of the reference image exceeds a storing capacity of the internal storing circuit by the storing capacity determination unit.
