Abstract: An imaging system includes: an imaging unit that captures an image of an eye area of a target person by using an image sensor that allows imaging without saturating observed light; an acquisition unit that obtains, from the image, a first information about a first area that does not include reflection of light by an eyeglass lens of the target person, and a second information about a second area that includes the reflection of the light; and a correction unit that corrects the second information so as to reduce an influence of the reflection, on the basis of the first information. According to such an imaging system, it is possible to properly capture the iris image even when the target person is wearing eyeglasses.

Abstract: An information processing system includes: a reference image acquiring unit that acquires a reference image; a bracketing unit that controls a camera to perform bracketing based on the reference image; a histogram acquiring unit that acquires a histogram of the reference image; and an additional imaging unit that controls the camera to perform additional imaging with a set value different from that of the bracketing imaging, on the basis of the histogram of the reference image. According to such an information processing system, it is possible to capture an appropriate image, regardless of an imaging environment.

Abstract: To provide a system, a method and the like for acquiring more images or more quickly focused images. A control device acquires information regarding a situation of a range captured by an imaging device, determines a mode according to an assumed situation of the range captured by the imaging device among a plurality of focusing modes, and transmits designation information specifying the determined mode to the imaging device. The imaging device receives the designation information from the control device, and captures an image using the mode specified by the received designation information.

Abstract: An image acquisition unit (2) acquires an image obtained by capturing at least eyes of a target person. An object specifying unit (4) specifies an object in a line-of-sight direction of the target person using the acquired image. An incident light amount calculation unit (6) calculates an incident light amount representing an amount of light incident on the eyes of the target person using the acquired image. A reference pupil size determination unit (8) determines a reference pupil size based on the calculated incident light amount. A pupil size calculation unit (10) calculates a pupil size of the target person using the acquired image. An interest determination unit (12) determines an interest of the target person in the object by comparing the determined reference pupil size with the calculated pupil size.

Abstract: Iris image pick-up devices perform image pick-up of an iris of a moving subject. A guiding device guides the subject. A controller predicts a period in which the subject will blink next. Further, the controller predicts a period in which the subject will pass through the focusing point of the iris image pick-up devices. The controller controls the guiding device such that the subject does not blink at the focusing point in the case where the period in which the subject will blink next overlaps with the period in which the subject will pass through the focusing point.

Abstract: A controller controls the readout of an image from iris image pick-up devices for performing image pick-up of an iris of a subject. In the control of the readout of an image from the iris image pick-up devices, the controller sets a region of interest to be treated as a target of the image readout. The controller stores past information, and in the case of performing image processing on the same subject, the controller determines whether or not an eye region of the subject was successfully covered by the region of interest used in the past. In the case of determining that the eye region of the subject was not successfully covered, the controller corrects the readout of an image from the iris image pick-up devices.

Abstract: Iris image pick-up devices perform image pick-up of an iris of a moving subject. Images from the iris image pick-up devices are written to storage areas for transfer in a memory. A readout device reads out an image stored in the storage areas for transfer to a storage area for image processing at a frame interval corresponding to the movement speed of the subject. An image processing unit executes processing using the image read out to the storage area for image processing.
