1. A recording reproduction control device comprising:
a hardware processor that executes machine-executable units, comprising:
a moving image data acquisition unit configured to acquire moving image data of a predetermined frame rate output from a camera as an input, and to output the moving image as a first video stream;
a trigger signal acquisition unit configured to output a trigger signal based on a signal input from an external device;
a captured image generator unit configured to output a captured image by extracting one frame from the first video stream based on the trigger signal output from the trigger signal acquisition unit;
a frame interpolation unit configured to, with the captured image output from the captured image generator unit as an input, interpolate at least one frame image at the predetermined frame rate and output the captured image and the interpolated frame image over a period until a new captured image is input;
a storage controller unit configured to sequentially record the captured images output from the captured image generator unit as a second video stream in a storage and record the captured images and the interpolated frame images in array as a third video stream; and
a reproduction controller unit configured to reproduce the second video stream or the third video stream recorded in the storage,
wherein the captured image generator unit is further configured to input a first captured image and a second captured image chronologically to the frame interpolation unit, and
the frame interpolation unit is further configured to interpolate, as the frame image, a mixture image obtained by mixing the first captured image and the second captured image based on a time ratio of a time at which the first captured image was input and a time at which the second captured image was input.
