An image acquiring device comprises a first camera (14) for acquiring video images, consisting of frame images continuous in time series, a second camera (15) in a known relationship with the first camera for acquiring two or more optical spectral images of an object to be measured and an image pickup control device (21). The image pickup control device (21) is configured to extract two or more feature points from one of the frame images, to sequentially specify the feature points in the frame images, to perform image matching between the frame images regarding the frame images corresponding to the two or more optical spectral images based on the feature points, and to synthesize the two or more optical spectral images according to the condition obtained by the image matching. |
