Imaging Apparatus Focus Check via Dynamic Display Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multiple exposure shooting, users cannot easily check the focus adjustment state and composition of the image to be shot after automatic focus processing is completed, requiring cumbersome operations to adjust and re-shoot.
Innovation Solution
An imaging apparatus that generates a multiple image combination result image by combining a through-the-lens image and already captured images, allowing sequential display updates during focus adjustment and after focus is complete, enabling users to easily check the focus state and composition before shooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display is switched to show only the through-the-lens image during focus adjustment, then the user can check the focus adjustment state, but the user cannot check the composition of the combined image after focus adjustment is completed
Solution Approach 1:
The display dynamically switches between showing only the through-the-lens image during focus adjustment and showing the combined image after focus adjustment is completed. This dynamic adaptation allows the display to provide different information at different stages of the shooting process, resolving the contradiction between focusing and composition checking
Solution Approach 2:
The system performs preliminary focus adjustment using the through-the-lens image, then transitions to displaying the combined image for composition checking before actual shooting. This preliminary action sequence ensures both focus and composition are optimized
2Loss of information
If the user releases the shutter button to check composition, then the user can see the combined image, but the user must repeat the focus adjustment process
Solution Approach 1:
The display of the combined image continues uninterrupted after focus adjustment is completed, allowing the user to check composition without releasing the shutter button. This continuous display eliminates the need to repeat focus adjustment, saving time and maintaining operational efficiency
Solution Approach 2:
The system provides continuous visual feedback by displaying the combined image after focus adjustment, allowing the user to verify both focus and composition simultaneously. This feedback mechanism prevents unnecessary repeated operations
3Loss of information
If the display shows the combined image during focus adjustment, then the user can check composition, but the user cannot clearly check the focus adjustment state
Solution Approach 1:
The display dynamically adapts its content based on the shooting stage: showing only the through-the-lens image during focus adjustment for clear focus checking, and switching to the combined image after focus is completed for composition verification

AI summary
The present invention provides an imaging apparatus capable of facilitating a user's check of a focus adjustment state at the time of multiple exposure shooting, and also allowing a user to easily check in what kind of composition an image to be shot now will be combined with an already captured image immediately before shooting. The imaging apparatus includes a display control unit configured to perform control to display a through-the-lens image captured by an imaging unit on a display unit while sequentially updating the through-the-lens image during a focus adjustment, and display a multiple image combination result image generated by combining the through-the-lens image captured by the imaging unit and at least one already captured image on the display unit while sequentially updating the multiple image combination result image after completion of the focus adjustment.
