Power consumption of a circuit which makes a determination is reduced. The accuracy of a system which makes a determination is improved. The safety of a target object which is monitored by a sensor element is increased. A system which easily monitors a target object is provided. A semiconductor device includes a detection circuit having a function of analyzing first data and making a first determination of selecting a first value or a second value, a first determination circuit and a second determination circuit having a function of performing feature extraction of an image, a power supply circuit, and a power management unit. The power management unit has a function of allowing a voltage to be supplied from the power supply circuit to the first determination circuit in the case where the first value is selected by the first determination. The first determination circuit has a function of analyzing the first data and making a second determination. The second determination circuit has a function of analyzing the first data and making a third determination in the case where an occurrence of an event is detected in the second determination.

Abstract:
Color filters are used for color images obtained using imaging devices such as conventional image sensors. Imaging elements with color filters are sold, and an appropriate combination of the imaging element and a lens or the like is incorporated in an electronic device. Only providing a color filter to overlap a light-receiving region of an image sensor reduces the amount of light reaching the light-receiving region. An imaging system of the present invention includes a solid-state imaging element without a color filter, a storage device, and a learning device. As a selection standard for reducing the amount of learning data, in an HSV color space, saturation is used, and selection is performed so that the saturation has optimal distribution. When colorization disclosed in this specification is performed, the colorization and object highlight processing can be performed at the same time.
