A crosswalk detection device executes a predetermined arithmetic processing on a calculated value calculated based on data obtained through a scanning operation using a main pattern. Next, the device determines whether or not a crosswalk is in a predetermined image based on a relationship between a calculated result of the arithmetic processing and a position of the main pattern MP on the predetermined image. The above-explained calculated value is, for example, an average of the brightness of pixels overlapping each sub pattern of the main pattern. Hence, even if a white pattern of the crosswalk is cracked or the white pattern has a separated part, the value of data is hardly affected. Accordingly, it is possible to precisely determine whether or not the crosswalk is in the predetermined image.

A computer () obtains a facial image acquired by picking up an image of a person subjected to image pickup from a camera (), and estimates a facial expression of the person subjected to image pickup based on the obtained facial image. Next, the computer obtains an eye open level of the person subjected to image pickup based on the facial image, and sets a threshold of the eye open level based on the estimated facial expression of the person subjected to image pickup. When the eye open level exceeds the threshold, the computer () determines that the eye of the person subjected to image pickup is opened. Moreover, when the eye open level does not exceed the threshold, the computer determines that the eye of the person subjected to image pickup is closed.
