摘要:
An exposure control apparatus for controlling an exposure adjustment mechanism on the basis of a captured image signal includes the following elements. A face detecting unit detects a face of a person appearing in a captured image on the basis of the captured image signal. A histogram data determining unit determines histogram data by setting a face detection region in the captured image according to detection information and detecting at least a brightness value of the face detection region from the captured image signal. A target brightness setting unit sets a target brightness range for desired brightness of the face. An exposure control amount determining unit determines, when a face is detected, an amount of control for the exposure adjustment mechanism by comparing the target brightness range with a brightness value at a peak of the histogram data or a brightness region in the vicinity of the peak.
摘要:
To provide a small active oxygen generating device capable of efficiently continuously generating active oxygen while supplying oxygen in the air. In the active oxygen generating device in which water is made to exist between an anode and a cathode composed of a base material containing a conductive polymer and by turning on electricity between the anode and the cathode, the conductive polymer deoxidizes the oxygen dissolved in the water to generate active oxygen, the cathode is rotatably installed about a conductive horizontal axis with part of the surface being projected over the surface of the water.

An imaging apparatus can photograph without making a user feel a wasteful photographing impossible time and stress. The imaging apparatus has a light emission unit; an anticipated temperature calculator that calculates an anticipated temperature of the light emission unit based on a light emission state; and a controller for suppressing a charging current or a light emission energy of the light emission unit based on the anticipated temperature.
