This paper demonstrated the design and implementation of a unique algorithm
used to generate interim coordinates for focus transitions in time-lapse
photography. Through a prototype design methodology, the unique algorithm
was developed to function within the limitations imposed by a low-cost 8-bit
microcontroller for the development of a cost-effective focus and motion
control system for deployment in photographic higher education. Through
conceptualization and virtualization in MathLab and comparison with values
generated in simulated real-world use-case, the proposed algorithm was
tested for function and efficacy in generating interim coordinates that
included focus coordinate estimation to facilitate smooth non-linear motion
with focus transitions during image sequence capture. The 8-bit Arduino
Mega 2560 proved capable of completing calculations required by the developed
algorithm and generated coordinate data sets identical to sets generated in
simulation. The generated coordinated illustrated effective user-defined control
over motion and the smoothness of focus transitions. The developed algorithm
is thus capable of facilitating the required movement and focus transition
coordinate calculation and estimation required while deployed on a low-cost
8-bit microcontroller and is well suited for deployments in time-lapse
capture applications.
