Note that in the present embodiment, the focus guide function is provided based on the defocus amount and direction obtained by using a configuration for image plane phase difference-based focus detection. However, the basic technical spirit of the present embodiment does not depend on the method of obtaining the degree of focus in the focus detection region. Therefore, a focus guide function may be provided for each imaging optical system based on other evaluation values that depend on the degree of focus of the image formed by the individual imaging optical system, such as, for example, contrast evaluation values or the like.
Focus Guide Display Control Processing
The focus guide display control processing executed by the system control unit 218 will be described next with reference to the flowchart in
The focus guide display control processing described here does not depend on the number of optical axes (number of imaging optical systems) included in the mounted lens unit. The focus guide display control processing may be executed for each image formed by the imaging optical system.
