An optical tomographic information generating device which generates optical tomographic information of a subject by using an updated value has: a Jacobian matrix computing unit that computes a Jacobian matrix that expresses a proportion of change in a light intensity distribution with respect to change in an optical characteristic value of the subject; a singular value decomposing unit that acquires a diagonal matrix of the Jacobian matrix; a unit diagonal matrix acquiring unit that acquires a unit diagonal matrix in which diagonal components that are less than or equal to a threshold value are replaced by 0; and a successive approximation unit that carries out approximation by carrying out substitution, that uses the unit diagonal matrix, with respect to a difference between an actually measured value and the computed value that appears in a successive approximation formula of ART (Algebraic Reconstruction Technique), and acquires the updated value. |
