Method for Distance Ranging Combining Time of Flight Sensor with Aiming Dot Parallax Detection

Imaging devices, systems, and methods for capturing and processing images, by using multiple distance determinations to set the focal position of variable-focus lens are provided. Imaging devices include a low-resourced depth sensor detecting an object distance over a first field of view (FOV). The imaging devices include an imaging sensor determining an object distance over a second FOV using parallax detection of an aiming pattern. Processors are configured to compare the two distances and, in response, to discordance perform a series of mitigations to determine a desired distance. The variable-focus lens is then set to that desired distance for subsequent image capture and indicia analysis.
