Claim Text:
1. An apparatus for determining image conversion parameters for correcting deviation between a plurality of images captured by a plurality of image capturing units comprising: a computer, a memory, and a program installed on the memory executed by the computer to: calculate an image conversion parameter to correct deviation in up and down direction of the plurality of images according to image analysis to the plurality of images captured by the plurality of the image capturing units at an initial position of a zoom lens of the image capturing unit; calculate a reliability degree of the image conversion parameter according to image analysis to the plurality of images captured by the plurality of the image capturing units at the initial position of the zoom lens of the image capturing unit, the reliability degree being calculated based on at least one of a number of correspondence points between the plurality of images, and a distribution of the correspondence points; for a first set of images of the plurality of images captured, where the reliability degree calculated for the first set of images at the initial position is equal to or more than a predetermined threshold value, sequentially move the zoom lens from a telescopic side to a wide angle side, and calculate the image conversion parameter for each zoom position of the zoom lens, the zoom position being at wider angle side than the initial position, according to the image analysis to the plurality of images captured by the plurality of the image capturing units; and for a second set of images of the plurality of images captured, where the reliability degree calculated for the second set of images at the initial position is less than the predetermined threshold value, output to a user an alert of request to change an angle of each of the plurality of image capturing units without calculating the image conversion parameter for each zoom position of the zoom lens.
