Abstract: A control section 35 compares angles of view of a main captured image generated by a main imaging section 21 and a subordinate captured image generated by a subordinate imaging section 22. In a case where a result of comparison, by the control section 35, of the angles of view indicates that the angle of view of the main captured image is narrower than the angle of view of the subordinate captured image, an image synthesis section 24 generates a display image by superimposing the main captured image on the subordinate captured image or superimposing the reduced subordinate captured image on the main captured image. In a case where the angle of view of the main captured image is narrower than the angle of view of the subordinate image, the main captured image is set as the display image. It is possible to easily decide a composition during shooting by using the subordinate captured image. It is also possible to confirm an imaging status by using the main captured image.

Abstract: A semiconductor device includes a connector connectable to a host, a power supply circuit which includes an input portion that receives first power from the host via the connector, an output portion, and a switch that is connected to the input portion and the output portion and controls whether to supply the first power to the output portion, the power supply circuit generating second power and third power from the first power, a semiconductor memory which receives the second power from the output portion, and a controller which receives the third power from the output portion and controls the semiconductor memory. The power supply circuit turns off the switch and stops supply of power to the semiconductor memory and the controller when the second power exceeds a first value or when the third power exceeds a second value.

Abstract: An electronic device includes a first electronic unit, a second electronic unit disposed adjacent to the first electronic unit, and a heat radiating unit. The second electronic unit has a first portion and a second portion that is closer to the first electronic unit than the first portion. The heat radiating unit is disposed such that heat generated in the second portion of the second electronic unit is directed towards the first portion of the second electronic unit and from the first portion towards an outside of the electronic device.
