Interchangeable Lens Camera Image Correction Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems with interchangeable lenses do not effectively improve user convenience by displaying corrected image data on an LCD monitor, as they fail to address issues like increased correction speed, handling lenses beyond correction limits, and displaying corrected images in a timely manner.
Innovation Solution
A camera system with an imaging unit, acquisition unit, correction unit, and display unit that acquires optical data from the interchangeable lens, corrects image data based on this data, and only displays the image after the correction is complete, preventing the display of distorted images until the process is finished.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the camera body displays image data immediately after capture, then the response speed is fast, but the user views distorted images before correction is complete
Solution Approach 1:
The camera body performs distortion correction processing on the captured image data before displaying it on the LCD monitor. The correction unit acquires optical data from the interchangeable lens and uses it to correct the image data in advance, ensuring that only corrected images are displayed to the user.
2Reliability
If the camera body performs distortion correction processing, then the image quality is improved, but the time required for correction increases
Solution Approach 1:
The camera body performs distortion correction processing on the captured image data before displaying it on the LCD monitor. The correction unit acquires optical data from the interchangeable lens and uses it to correct the image data in advance, ensuring that only corrected images are displayed to the user.
3Measurement precision
If the camera body stores optical data from the interchangeable lens, then the correction accuracy is improved, but the device complexity increases
Solution Approach 1:
The interchangeable lens itself stores the optical data (including distortion characteristics) in its own storage unit. When mounted on the camera body, the lens automatically transmits this data to the camera body, eliminating the need for the camera body to have a separate database of lens specifications and reducing the overall system complexity.

AI summary
A camera body to which an interchangeable lens is mountable, 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, and a display unit operable to display an image based on the image data. After the camera body is turned on, the display unit does not display the image based on the image data generated by the imaging unit, until the correction unit completes correction of the image data generated by the imaging unit.
