1. An image-capture device comprising: an image-capture section that captures an image of a subject; a detector that detects a portion of the subject, the portion having a specific feature, from the image captured by the image-capture section; an evaluator that determines a numerically expressed evaluation value of the specific feature of the portion detected by the detector; a buffer section that temporarily stores delayed images corresponding to a predetermined amount of time; and a recording-operation controller that controls the image-capture device to record image data including a predetermined delayed image in the buffer section, upon determining that the evaluation value satisfies a predetermined condition, in which the buffer section stores a number of evaluation values in a period of time so as to form an evaluation value history, and in which the recording-operation controller determines a start image for recording in the buffer section based on the evaluation value history when the evaluation value is determined to satisfy the predetermined condition.
