Imaging Apparatus Through Image Display for Focus Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multiple exposure photography, it is difficult to clearly view the through image when confirming the focus status due to the overlay of the through image with the synthesized image during magnification in live view displays.
Innovation Solution
An imaging apparatus that allows the display of a through image without multiple synthesizing when a magnification instruction is received, enabling easy focus status confirmation while maintaining a multiple live view display suitable for composition adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple-synthesis display is performed during live view in multiple exposure photography, then composition adjustment is facilitated, but through image visibility deteriorates when magnification is applied for focus confirmation
Solution Approach 1:
The display mode dynamically switches between multiple-synthesis display and through-image-only display based on the operational state. During normal live view, multiple-synthesis display is active for composition adjustment. When magnification is detected (indicating focus confirmation need), the system transitions to through-image-only display, allowing the user to clearly view focus status without the synthesized image overlay.
2Loss of information
If through image is displayed with multiple-synthesis during magnification, then composition information is preserved, but focus status confirmation becomes difficult
Solution Approach 1:
When magnification is detected, the system extracts and displays only the through image, removing the synthesized image overlay that obscures the through image details. This extraction allows the user to clearly view the through image for focus confirmation. After magnification ends, the synthesized image is restored for composition adjustment.
3Adaptability or versatility
If multiple live view display is maintained during magnification, then composition adjustment capability is preserved, but focus confirmation accuracy deteriorates
Solution Approach 1:
The display mode periodically switches between multiple-synthesis display and through-image-only display based on the magnification state. When magnification starts, the system switches to through-image-only mode for accurate focus confirmation. When magnification ends, it returns to multiple-synthesis display for composition adjustment, creating a periodic transition that maintains both functionalities at appropriate times.

AI summary
The present invention is directed to an imaging apparatus configured to display a through image in a visible manner when it is assumed that a status of a focus is confirmed even if a multiple live view display suitable for composition adjustment is performed in multiple exposure photography. The imaging apparatus includes a generation unit configured to multiple-synthesize a through image and at least a captured image, and to generate a multiple-composite image, a display control unit configured to perform control to display the multiple-composite image on a display unit while sequentially updating the multiple-composite image, a magnification instruction receiving unit configured to receive an image magnification instruction, and a control unit configured to perform control to display a through image magnified without multiple-synthesizing, on the display unit when receiving the magnification instruction while displaying the multiple-composite image.
