Wireless Peaking Image Emphasis for Manual Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses lack the ability to easily emphasize and display the in-focus part of a captured image wirelessly to a display device, making it difficult for users to confirm focusing, especially in manual focus modes.
Innovation Solution
An imaging apparatus that includes an imaging unit, a peaking processor, and a sending unit, which captures images, adjusts emphasis of the in-focus part based on image quality settings, and wirelessly sends a peaking image to a display device, such as a smartphone, allowing users to easily check focusing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the peaking function is performed on the captured image to emphasize the in-focus part, then the user can easily identify the in-focus position, but the image quality and detail may be degraded due to the emphasis processing
Solution Approach 1:
The patent divides the image processing into two separate paths: one path applies peaking emphasis processing to generate an image for displaying focus position, while another path preserves the original captured image data without emphasis processing. This segmentation allows the system to provide both focus identification capability and high-quality image output independently, resolving the contradiction between ease of identifying in-focus position and image quality preservation.
2Ease of operation
If the peaking image is sent to a display device via wireless communication, then the user can check the in-focus part on a remote device, but the transmission time and data usage increase
Solution Approach 1:
The patent applies partial action by selectively transmitting only the peaking-processed image data to the display device when needed for focus verification, rather than continuously transmitting all image data. The system allows users to optionally enable peaking function and only processes/transmits images when this function is active, reducing unnecessary transmission time and data usage while maintaining the ability to check in-focus parts when required.
3Ease of operation
If the peaking process is applied to all captured images, then the in-focus part is always emphasized, but the processing load and power consumption increase
Solution Approach 1:
The patent implements a dynamic peaking processing system where the application of peaking emphasis is controlled by a user-selectable setting. The system can dynamically switch between applying peaking processing to all images, applying it only to specific images based on focus verification needs, or not applying it at all. This dynamic control allows the system to adapt power consumption to actual user needs, maintaining consistency of focus indication when required while reducing power consumption when the peaking function is not needed.
