Abstract: An information presenting system includes: a specification unit that specifies a position of a biological part used for authentication from information about a target person; a setting unit that sets an imaging area in which the biological part is imaged, in accordance with the specified position of the biological part; and a presentation unit that presents information indicating the imaging area at a position that allows an overlap of the biological part. According to this information presenting system, information about biometric authentication can be appropriately presented to the target person, so that an authentication process can be performed normally.

Abstract: A parameter optimization system (10) includes: an image sensor (110) having at least one sensing parameter; a parameter setting unit (120) configured to be able to change the sensing parameter; a score calculation unit (130) configured to calculate a score from an image acquired by the image sensor; and a parameter determination unit (140) configured to determine a right parameter value that is a value of the sensing parameter at which the score is relatively high, based on a value of the sensing parameter and the score corresponding to the value of the sensing parameter. According to such a parameter optimization system, the sensing parameter of the image sensor can be set to an appropriate value.
