1. An imaging device, comprising:

  • image signal acquisition means for acquiring an image signal in an electrical form by converting input image-bearing light into the image signal;

    data generation means for generating successively image data containing a still image by inputting successively the image signal corresponding to one still image unit;

    data storage control means for storing, on a predetermined memory thereof, the image data generated by the data generation means, the image data acquired in retrospect within a unit time before a current time point;

    record control means for recording, on a recording medium, the image data prior to a shutter release operation and the image data subsequent to the shutter release operation, the shutter release operation being performed to acquire the image data in response to an operation timing and to store the acquired image data onto the recording medium, the image data prior to the shutter release operation being stored on the data storage control means at the timing of the shutter release operation, and the image data subsequent to the shutter release operation being generated during a predetermined period of time extending from the timing of the shutter release operation to a later time point;

    operation means for performing an operation to modify a pixel count of the image data on one of the image data prior to the shutter release operation and the image data subsequent to the shutter release operation, the image data containing a two-dimensional set of pixels; and

    pixel count setting control means for controlling setting of the pixel count so that the pixel count of one of the image data prior to the shutter release operation and the image data subsequent to the shutter release operation specified in the operation performed by the operation means reaches the pixel count specified in the operation of the operation means and so that the pixel count of the other of the image data prior to the shutter release operation and the image data subsequent to the shutter release operation reaches a predetermined pixel count set as a standard value.
