Abstract:
(EN) The purpose of the present invention is to provide an electronic device, an imaging device, and a power supply switching method capable of, when a power supply line is shut off between a device body and an external device capable of mounting a plurality of power supplies, smoothly switching the power supplies while preventing an abrupt shutoff. In the electronic device according to one embodiment of the present invention, a power supply switching preparation unit performs a process including a first process for bringing the electronic device into a power saving state as a preparation for switching and a second process for bringing the power into an available state from the plurality of power supplies, and a power supply switching control unit switches main power supplies in a set priority order with the switching preparation being performed. Therefore, in an electronic device in which a power supply line is shut off between a device body and an external device capable of mounting a plurality of power supplies, the power supplies can be smoothly switched while preventing an abrupt shutoff.
(FR) Le but de la présente invention est de fournir un dispositif électronique, un dispositif d'imagerie, et un procédé de commutation d'alimentation électrique permettant, lorsqu'une ligne d'alimentation électrique est coupée entre un corps de dispositif et un dispositif externe pouvant monter une pluralité d'alimentations électriques, de commuter en douceur les alimentations électriques tout en évitant une coupure brutale. Dans le dispositif électronique selon un mode de réalisation de la présente invention, une unité de préparation de commutation d'alimentation électrique réalise un processus comprenant un premier processus destiné à mettre le dispositif électronique en état d'économie d'énergie en tant que préparation de la commutation et un second processus destiné à mettre l'alimentation en état de disponibilité à partir de la pluralité d'alimentations électriques, et une unité de commande de commutation d'alimentation électrique commute des alimentations électriques principales dans un ordre de priorité défini, la préparation de commutation étant effectuée. Par conséquent, dans un dispositif électronique dans lequel une ligne d'alimentation électrique est coupée entre un corps de dispositif et un dispositif externe pouvant monter une pluralité d'alimentations électriques, les alimentations électriques peuvent être commutées en douceur tout en évitant une coupure brutale.
(JA) 本発明は、複数の電源を装着可能な機器本体と外付機器との間で電源供給ラインが互いに遮断されている場合に、瞬断を防止しつつ電源を円滑に切り替えられる電子機器、撮像装置、及び電源切替方法を提供することを目的とする。本発明の一の態様に係る電子機器では、電源切替準備部は切替準備として、電子機器を省電力状態に移行させる第1の処理と、複数の電源から電力を供給可能な状態に移行させる第2の処理と、を含む処理を行い、電源切替制御部は切替準備が行われた状態で主電源を設定された優先順位で切り替えるので、複数の電源を装着可能な機器本体と外付機器との間で電源供給ラインが互いに遮断されている電子機器において、瞬断を防止しつつ電源を円滑に切り替えることができる。
