Definitions

  • the RAM 12 temporarily stores computer programs executed by the processor 11.
  • the RAM 12 temporarily stores data temporarily used by the processor 11 while the processor 11 is executing the computer program.
  • the RAM 12 may be, for example, a D-RAM (Dynamic Random Access Memory) or an SRAM (Static Random Access Memory). Also, instead of the RAM 12, other types of volatile memory may be used.
  • FIG. 4 An information processing system 10 according to the second embodiment will be described with reference to FIGS. 4 to 6.
  • FIG. It should be noted that the second embodiment may differ from the above-described first embodiment only in part of the operation, and other parts may be the same as those of the first embodiment. Therefore, in the following, portions different from the already described first embodiment will be described in detail, and descriptions of other overlapping portions will be omitted as appropriate.
  • the focus control unit 120 may change only one of the first reference distance and the second reference distance.
  • the focus control section 120 may change the first reference distance so as to gradually decrease, while leaving the second reference distance initially set unchanged (fixed).
  • the focus control unit 120 may gradually increase the second reference distance while keeping the first reference distance unchanged (fixed).
  • the focus control unit 120 starts control to change the focal length of the camera 18 at the focus change speed set by the speed setting unit 110 (step S102). Then, the imaging control unit 130 controls the camera 18 so as to perform imaging with the first focal length and the second focal length (step S103). After that, the focus control unit 120 ends the control for changing the focal length of the camera 18 (step S104).
  • the focus control unit 120 starts control to change the focal length of the camera 18 at the focus change speed set by the speed setting unit 110 (step S102). Then, the imaging control unit 130 controls the camera 18 so as to perform imaging with the first focal length and the second focal length (step S103). After that, the focus control unit 120 ends the control for changing the focal length of the camera 18 (step S104).
  • the change of the focus change speed described above may be performed multiple times. That is, the focus change speed may be changed multiple times during the period until the imaging control unit 110 finishes imaging. However, an interval between one change and the next change may be set, or an upper limit on the number of changes may be set.
  • the authentication unit 160 is configured to be able to perform authentication processing using the image selected by the selection unit.
  • the type of authentication processing executed by the authentication unit 160 is not particularly limited, it may be configured to be able to execute biometric authentication processing using a target image, for example.
  • the authentication unit 160 may be configured to be able to execute iris authentication processing using a target iris image.
  • the authentication unit 160 may be configured to be able to perform face authentication processing using a target face image.
  • the authentication unit 160 may be configured to be capable of executing multimodal authentication processing using a plurality of target parts.
  • the authentication unit 160 may have a function of executing predetermined processing based on the result of authentication processing.
  • the authentication unit 160 may be configured to be capable of executing a process of opening a gate when the authentication process is successful and closing the gate when the authentication process is unsuccessful.
