Imaging control device, imaging apparatus, imaging control method, and imaging control program

An imaging control method comprising:

• a drive control step of controlling a driver of an imaging sensor which includes a plurality of pixels each including a photoelectric converter and a charge holder which holds charges transferred from the photoelectric converter and from which a signal corresponding to the charges is read out by a reading circuit, and an imaging surface on which a plurality of pixel rows each including a plurality of the pixels arranged in a first direction are arranged in a second direction orthogonal to the first direction to consecutively perform driving of starting exposure of the plurality of pixels by resetting the photoelectric converter of each of the plurality of pixels at the same time, ending the exposure by transferring the charges accumulated in the photoelectric converter of each of the plurality of pixels by the exposure to the charge holder at the same time, and then, sequentially selecting the pixel row from one end side to another end side of the imaging surface in the second direction, and reading out a pixel signal corresponding to the charges held in the charge holder of the selected pixel row;
• a moving object detection step of performing a process of dividing captured image data generated based on the pixel signal read out by the driving into a plurality of areas in the second direction and detecting a moving object from the area based on a result of comparing the generated area with the same area as the area in the captured image data generated based on the pixel signal read out by the driving performed before the driving;
• and
• a recording control step of predicting a timing at which a range set in the captured image data overlaps with the moving object based on a change in position of the moving object detected in the moving object detection step and processing the pixel signal read out by the driving executed in a period including the timing as a signal for recording on a recording medium, and
• wherein a timing at which generation of an area that is generated based on the pixel signal read out from the pixel row on the other end side of the imaging surface from the pixel row from which the pixel signal of a generation source of a first area including the range in the captured image data generated based on the pixel signal read out by the driving is completed is present in a period in which the driving is performed after the driving is performed twice, and
• the plurality of areas include the first area, at least three second areas that are generated based on the pixel signal read out from the pixel row on the one end side of the imaging surface from the pixel row from which the pixel signal of the generation source of the first area is read out, and at least four third areas that are generated based on the pixel signal read out from the pixel row on the other end side of the imaging surface from the pixel row from which the pixel signal of the generation source of the first area is read out.
