Abstract: According to one embodiment, in order to manage the remaining capacity of a secondary battery of an information recording/reproduction device, the remaining capacity of the secondary battery which supplies electric power to the whole device including a storage medium is monitored in accordance with current supply capacity and in accordance with voltage supply capacity. The remaining capacity is displayed on a display in accordance with the current supply capacity. The whole device is stopped when one of the current supply capacity and the voltage is below a system stop level indicating the electric power required on the startup of the storage medium.

Abstract: According to one embodiment, a medium controller controls communication between one, which is selected, of an HDD and an SD card and an MPEG Coder. A switch selects one of the HDD and the SD card, and connects the selected recording medium to the medium controller. A DSP controls connection of the switch according to an instruction input through a user interface.

Abstract: A television camera equipped with an active filter section capable of producing dynamic special effects in the picture. The filter section of the camera includes an electro-optic light control device which is arranged in the optical path of the imaging optical section of the television camera such that its light transmittance for the incident light to the image screen of the camera is varied in response to the application of an electric signal, and the variable transmittance area is divided into a plurality of sections adapted to be controlled and drived selectively. Also, the camera includes a drive unit for selectively controlling and driving the sections of the electro-optic light control device so as to vary with time the spread of the area of the sections having the transmittance varied in response to the application of the electric signal.
