PROBLEM TO BE SOLVED: To provide an apparatus and a method for simultaneously acquiring spectroscopic information and shape information, which can simultaneously and easily acquire a shape of an object body and its surface information (texture information). SOLUTION: The apparatus for simultaneously acquiring a geometric shape of the object and its surface texture information comprises: four or more image acquiring means equipped with optical filters respectively having different spectral transmission characteristics; a synchronizing means for synchronizing timings at which respective image acquiring means acquire image data sets; a shape information acquiring means for acquiring the geometric shape information of the object, based on a positional relation of the image acquiring means and a difference of corresponding point position between image data sets acquired in synchronization with another by the image acquiring means caused by a difference of view point position of respective image data sets; and a spectroscopic information acquiring means for acquiring the texture information of the object surface from brightness values of pixels making up an overlapping area between respective image data sets acquired by the image acquiring means equipped with the optical filters having the different spectral transmission characteristics.
