Abstract: An imaging apparatus includes an image sensor, a shutter, a memory, a temperature acquisition unit, a determination unit, and an acquisition controller. The image sensor includes an effective pixel region and an optical black region. The memory temporarily stores photoelectric-converted image data after the shutter is opened. The temperature acquisition unit acquires an ambient temperature when the temperature is determined to be equal to or more than a threshold value when the image data is stored in the memory. The acquisition controller makes control for shutting the shutter and for acquiring photoelectric-converted image data at that time when the temperature is equal to or more than the threshold value. The writing unit cuts out image data of the effective pixel region from the acquired image data. Difference in optical black level is corrected using the cut-out image data.

Abstract: Based on information security rules, it is not possible to take out a failure HDD to the exterior of a facility for replacement without erasing data therefrom. According to the present storage sub-system, a slot in which failure has occurred and a slot not registered to a configuration information of a storage sub-system are used to simultaneously perform correction copy to a spare HDD and data erase of the failure HDD in parallel, so as to enable the failure HDD to be brought out to the exterior of the storage facility. Further, time required from when failure has occurred to the HDD to data recovery is shortened, so as to prevent deteriorated redundancy that may be caused by another failure occurring during data recovery and to reduce the risk of data loss.
