Recording control apparatus for plurality of images, recording control method for plurality of images, and non-transitory computer readable medium storing plurality of images

A recording control apparatus for a plurality of images, the recording control apparatus comprising:

• a plurality of cameras;
• an auxiliary power unit;
• an acceleration sensor;
• an electric power supply source switch configured to switch an electric power supply source to the auxiliary power unit from a main power unit when an electric power supply from the main power unit is cut off;
• and
• a processor coupled to a memory storing instructions to permit the processor to function as:
• an electric energy calculation unit configured to calculate auxiliary electric energy serving as electric energy capable of being supplied by the auxiliary power unit;
• a recorder configured to record images captured by the cameras in image files for respective cameras of the plurality of cameras;
• and
• a degree-of-importance determination unit configured to determine one of the image files of the images, captured by a cameras having an image capturing direction closest to a direction opposite to a direction of acceleration detected by the acceleration sensor among the plurality of cameras, as an image file having a highest degree of importance,
• wherein the recorder executes a close processing on the image file having the highest degree of importance, and starts to record a newly captured image captured by a camera having an image capturing direction closest to a direction opposite to a direction of acceleration detected by the acceleration sensor as a new image file, the close processing being a process of completing information in a format of each of image files to be established as a file abled to be handled by other devices.

A recording control method of a recording control apparatus for a plurality of images including an auxiliary power unit, the method comprising:

• acquiring captured images from a plurality of cameras;
• switching an electric power supply source to the auxiliary power unit from a main power unit when an electric power supply from the main power unit is cut off;
• calculating auxiliary electric energy serving as electric energy capable of being supplied by the auxiliary power unit;
• recording the images captured in the acquiring captured images in image files for respective one of the plurality of cameras
• determining one of the image files of the image captured by cameras, having an image capturing direction closest to a direction opposite to a direction of acceleration detected by an acceleration sensor among the plurality of cameras, as an image file having a highest degree of importance;
• and
• calculating a recordable duration time, during which the captured image is continuously recordable, by dividing auxiliary electric energy, serving as surplus power obtained by subtracting electric energy required for performing a close processing on the file from the auxiliary electric energy, by power consumption per unit time of the image recording apparatus in performing recording of the captured image, the close processing being a process of completing information in a format of each of image files to be established as a file abled to be handled by other devices,
• wherein the recorder sets a timing at which the close processing is executed on the image file having the highest degree of importance as a timing at which the recordable duration time has elapsed.
