Camera Body Lens Mount Detection Image Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems with interchangeable lenses lack convenience in displaying corrected image data, particularly during lens mounting and demounting, as they do not prevent the display of uncorrected images, which can be distorted or of poor quality.
Innovation Solution
A camera system with an imaging unit, acquisition unit, correction unit, detection unit, and display unit that controls the display of image data based on the lens's mounting state, ensuring that corrected images are shown only when the lens is properly mounted and uncorrected images are not displayed during demounting or mounting processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display unit continuously displays image data during lens mounting/demounting operations, then the user can maintain visual continuity, but poor quality uncorrected images will be displayed causing degraded image quality
Solution Approach 1:
The system performs preliminary detection of lens mounting state through detection unit before enabling image display. The control unit prevents display during mounting/demounting operations by detecting lens presence/absence and operational state in advance, ensuring only corrected images are displayed when lens is securely mounted.
Solution Approach 2:
The detection unit continuously monitors lens mounting state and provides feedback to the control unit. Based on this feedback, the control unit dynamically controls the display unit to enable or disable image display, creating a closed-loop system that adapts display behavior to current lens operational state.
2Reliability
If the correction unit continuously corrects image data during lens operations, then image quality is maintained, but processing resources are wasted when lens is not properly mounted
Solution Approach 1:
The correction unit dynamically adjusts its operation based on real-time lens mounting state detected by the detection unit. Correction processing is activated only when lens is securely mounted and deactivated during mounting/demounting operations, creating a dynamic on-demand correction system that adapts to operational conditions.
Solution Approach 2:
The system automatically manages correction processing without user intervention. The control unit monitors lens state and autonomously enables or disables correction processing based on detected mounting conditions, allowing the system to self-regulate resource consumption according to operational needs.
3Ease of operation
If the system displays uncorrected image data during lens demounting, then the display remains active providing continuous visual feedback, but distorted images will be displayed degrading user experience
Solution Approach 1:
The control unit applies preliminary anti-action by preventing display of uncorrected images before distortion can affect the user. When demounting is detected, the system proactively disables display rather than allowing distorted images to be shown, eliminating the harmful effect before it occurs.

AI summary
A camera body includes an imaging unit operable to generate image data by capturing an object image, an acquisition unit operable to acquire optical data of the interchangeable lens from the interchangeable lens, a correction unit operable to correct the image data generated by the imaging unit based on the optical data acquired by the acquisition unit, a detection unit operable to detect state of mounting/demounting the interchangeable lens to/from the camera body, and a display unit operable to display an image based on the image data. After detecting that the interchangeable lens is completely mounted to the camera body, when the detection unit detects that the interchangeable lens is being demounted from the camera body, the display unit stops displaying the image based on the image data. When the detection unit subsequently detects that the interchangeable lens is completely demounted from the camera body, the correction unit stops correcting the image data and the display unit displays the image based on the image data.
