Patent ID: 8395673

Claim:
A shooting device, comprising: a shooting unit which shoots a physical object as a shooting target, a position of the physical object being movable; an expected shooting state storing unit which stores expected shooting state information which represents an expected position of the physical object; a guide determining unit which determines how the physical object is to be guided to the expected position based on the expected shooting state information and an image shot by said shooting unit, said guide determining unit determines whether the physical object should be moved close to said shooting unit or away from said shooting unit by comparing a size of the physical object in the image shot by said shooting unit and a size of the physical object represented by the expected shooting state information; a guide instruction outputting unit which instructs how the physical object is to be guided to the expected position based on a result of the determination made by said guide determining unit, said guide instruction outputting unit outputs a guidance instruction for moving the physical object close to said shooting unit or moving the physical object away from said shooting unit, based on determination by said guide determining unit; and an image outputting unit which outputs the image shot by said shooting unit, wherein: the physical object possesses a physical line pattern including physical lines that are a part of the physical object; a number of physical lines or a total length of physical lines to be shot by said shooting unit is defined as the expected shooting state information; and said guide determining unit determines that the physical object is not required to be guided, if the number of the physical lines included in the physical line pattern possessed by the physical object or the total length of the physical lines included in the physical line pattern possessed by the physical object, which is detected from an image of the physical object shot by said shooting unit, is larger than the number of physical lines or the total length of physical lines, which is defined as the expected shooting state information.
