摘要： In a learning device (10), an optical conversion unit (11) receives light from a learning target and uses the received light to output light according to a configuration value of a parameter. A sensing unit (13) senses the light output from the optical conversion unit (11). An estimation unit (15A) forms an estimation result for an answer to a configuration problem based on the light sensed by the sensing unit (13). An update unit (15B) calculates an update value of the parameter of the optical conversion unit (11) based on the estimation result by the estimation unit (15A), and updates the configuration value of the parameter of the optical conversion unit (11) with the calculated update value. The optical conversion unit (11) includes a plurality of optical devices in which the configuration value of the parameter is set independently of each other.

摘要： 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.

摘要： 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.
