Abstract: An image processing apparatus obtains a motion vector between at least three images including first, second, and third images obtained through continuous shooting under different exposure conditions and computes a first motion vector between the first and second images and a second motion vector between the first and third images in a plurality of positions on the first image. A reliability level of the motion vector is determined, and an estimated motion vector between the first and second images is computed for the first motion vector having low reliability based on the second motion vector computed in the corresponding position and the shooting interval between the images. In a case where the second motion vector computed in a position corresponding to that of the first motion vector having low reliability has high reliability, the first motion vector having low reliability is substituted with the estimated motion vector.

Abstract: In a measuring device, a second objective optical system is arranged to have a parallax with respect to a first objective optical system. An imaging unit captures a first subject image formed through the first objective optical system at a first imaging timing and captures a second subject image formed through the second objective optical system at a second imaging timing different from the first imaging timing. A virtual image generating unit generates a virtual image based on the first subject image acquired in a case in which the imaging unit is assumed to capture the first subject image at the second imaging timing. A measurement processing unit measures a shape of a subject on the basis of a second image based on the second subject image and the virtual image.

Abstract: In a measurement device, an imaging unit generates a first image and a second image. A subject distance detection unit detects a subject distance. A motion detection unit detects an amount of motion of the imaging unit. A measurement availability determination unit determines whether or not measurement is executable by comparing the amount of motion with an allowable threshold value according to the subject distance. A measurement processing unit executes a measurement process on the basis of the first image and the second image when the measurement availability determination unit determines that the measurement is executable.
