A position designation device includes: a first position receiving section configured to cause a display device to display a synthesized image and to receive an input of a first position in the synthesized image via an input device; an image selecting section configured to select one of the captured images in accordance with the first position as a selected image; and a second position receiving section configured to cause the display device to display at least a part of the selected image and to receive an input of a second position in the selected image via the input device. ## Claims ### Claim 1 A position designation device comprising: a first position receiving section configured to receive an input of a first position in a synthesized image generated from a plurality of captured images; an image selecting section configured to select one of the captured images in accordance with the first position as a selected image; and a second position receiving section configured to receive an input of a second position in the selected image. ### Claim 2 (depends on 1) The position designation device according to claim 1, wherein the captured images have different exposure levels. ### Claim 3 (depends on 1) The position designation device according to claim 1, wherein the image selecting section selects one of the captured images as a selected image based on a grayscale saturation level of a subarea of each of the captured images, the subarea including the first position. ### Claim 4 (depends on 1) The position designation device according to claim 1, wherein the image selecting section calculates a grayscale saturation level of a subarea of each of the captured images, the subarea including the first position, and selects one of the captured images that has a minimum grayscale saturation level as a selected image. ### Claim 5 (depends on 1) The position designation device according to claim 1, wherein the captured images have different focal point locations. ### Claim 6 (depends on 1) The position designation device according to claim 1, wherein the image selecting section selects one of the captured images as a selected image based on a focusing level of a subarea of each of the captured images, the subarea including the first position. ### Claim 7 (depends on 1) The position designation device according to claim 1, wherein the image selecting section calculates a focusing level of a subarea of each of the captured images, the subarea including the first position, and selects one of the captured images that has a maximum focusing level as a selected image. ### Claim 8 (depends on 1) The position designation device according to claim 1, further comprising a measuring section configured to acquire depth information associated with the selected image and to calculate three-dimensional coordinates of a position on a subject in reference to the depth information, the position corresponding to the second position in the selected image. ### Claim 9 (depends on 1) The position designation device according to claim 1, further comprising a measuring section configured to acquire a reference image associated with the selected image and to calculate three-dimensional coordinates of a position on a subject in reference to the reference image, the position corresponding to the second position in the selected image. ### Claim 10 (depends on 1) The position designation device according to claim 1, further comprising: an image capturing section configured to capture a plurality of images as the captured images; and a synthesizing section configured to generate the synthesized image from the captured images. ### Claim 11 (depends on 1) The position designation device according to claim 1, wherein: the second position receiving section further receives an input of a third position in the selected image, the third position differing from the second position; the image selecting section re-selects the selected image in accordance with the third position; and the second position receiving section re-receives an input of the second and third positions in the selected image via the input device. ### Claim 12 (depends on 1) The position designation device according to claim 1, further comprising a display device and an input device. ### Claim 13 A method of designating a position, the method comprising: the first position receiving step of receiving a designation of a first position in a synthesized image generated from a plurality of captured images; the image selecting step of selecting one of the captured images in accordance with the first position received in the receiving step as a selected image; and the second position receiving step of receiving a designation of a second position in the selected image. ### Claim 14 A storage medium containing a program causing a computer to operate as: a first position receiving section configured to receive an input of a first position in a synthesized image generated from a plurality of captured images; an image selecting section configured to select one of the captured images in accordance with the first position as a selected image; and a second position receiving section configured to receive an input of a second position in the selected image.
