Abstract

The invention relates to a focus position correction device and method of a photographing device. A focus position correction device for an imaging device is provided with: a temperature detection device that detects an ambient temperature within an optical device of the imaging device; and a focusing device that performs, in a stepped manner, focus position correction for changes in the ambient temperature detected by the temperature detection device, in which the focal depth range of each step is set for a plurality of different ambient temperature ranges, and the focal depth ranges corresponding to adjacent ambient temperature ranges have portions that overlap each other. Thus, the change in the environment is divided into steps of a limited number of stages, and the image magnification change in each step is large, so that the ratio of magnification differences in the image caused by the deviation of the imaging optical systems is small, and the ratio is a negligible value in image synthesis, thereby obtaining a natural synthesized image.

Description

[0001] This application is a divisional application of the application whose filing date is "September 15, 2021", the application number is "2021110787564", and the invention title is "VR system, camera device for panoramic system and its control method". technical field [0002] The present disclosure relates to image photography synthesis technology, and in particular, to a focus position correction device and method of a photography device. Background technique [0003] Image photography synthesis systems such as VR systems and panorama systems that produce three-dimensional VR (Virtual Reality: Virtual Reality) images, panoramic images, and other synthetic images by taking pictures in all directions using multiple lens units and synthesizing the captured images have been developed. is widely used. This image capturing and combining system uses fixed focus and fixed focal length lens units, and since the characteristics of the respective lens units constituting the image ...
