An optical system consists of a front lens unit having a positive or negative refractive power, a diaphragm, and a rear lens unit having a positive refractive power, which are arranged in this order from an object side to an image side. The front lens unit includes an aspherical lens that has a positive refractive power on an optical axis, and is disposed closest to an object. The aspherical lens has an aspherical surface on the object side in which an off-axis radius of curvature is larger than an on-axis radius of curvature. A predetermined condition is satisfied.

An emotion estimation apparatus includes a recording section that records one or more events that cause a change in an emotion of a person and prediction information for predicting, for each event, an occurrence of the event; an event predicting section that predicts the occurrence of the event, based on detection of the prediction information; and a frequency setting section that sets a frequency with which an estimation of the emotion is performed. If the occurrence of the event is predicted by the event predicting section, the frequency setting section sets the frequency to be higher than in a case where the occurrence of the event is not predicted, and also sets the frequency based on the content of the event.
