Abstract:
1. An image taking system comprising: (a) a lighting device capable of changing a light emission time to a plurality of time length values that are different from each other; (b) an image taking device configured to take an image of a subject portion while light is being emitted by said lighting device; (c) a subject-portion moving device configured to move the subject portion relative to said image taking device, in a direction substantially orthogonal to an opposed direction in which said image taking device and the subject portion are opposed to each other, and capable of changing a movement velocity of the subject portion relative to said image taking device, to a plurality of velocity values that are different from each other; and (d) a control device configured, during movement of the subject portion by said subject-portion moving device, to cause said lighting device to emit the light for a given light emission time as one of the plurality of time length values and to cause said image taking device to take the image of the subject portion, and is configured to control the movement velocity at which the subject portion is moved by said subject-portion moving device, such that an amount of the movement of the subject portion for the given light emission time is not larger than a given movement amount that corresponds to an allowable amount of shake of the image, the allowable amount of shake of the image being a selected one of allowable image-shake amounts that are determined for respective light-reflectance combinations, each of the light-reflectance combinations being a combination of a light reflectance of the subject portion and a light reflectance of an adjacent portion adjacent to the subject portion.
