Image Processing Apparatus Background Compensation for Capture Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera devices experience delays between successive image captures due to image processing times, especially when various shooting options are applied, which can be inconvenient for capturing moving subjects or series of photos.
Innovation Solution
An image processing method that allows for rapid image conversion by processing shooting options in the background, enabling immediate subsequent shooting operations without waiting for image compensation to finish, by buffering full-resolution images and applying shooting options independently of the shooting mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image compensation is processed before entering preview mode, then image quality is improved, but delay time increases
Solution Approach 1:
The patent applies preliminary action by performing image compensation processing in advance during the integration period before the shutter button is pressed. The processor continuously accumulates signal values from the image sensor and performs compensation calculations during this time, so that when the shooting command is received, the processed image data is already prepared or nearly prepared, significantly reducing the delay time while maintaining image quality.
2Manufacturing precision
If shooting options are applied to full captured image, then image quality is improved, but processing time is significantly increased
Solution Approach 1:
The patent performs shooting option-based image compensation processing in advance during the integration period before the actual shooting command is executed. By continuously processing image data and accumulating compensated values during the preview mode operation, the system prepares processed image data beforehand, so that when the user presses the shutter button, the processing time is minimized while still applying all desired shooting options for improved image quality.
3Measurement precision
If image processing is completed before next shooting, then processing accuracy is improved, but shooting speed is reduced
Solution Approach 1:
The patent implements continuity of useful action by maintaining continuous image processing operations during the integration period. The processor continuously accumulates signal values from the image sensor and performs compensation processing without interruption, ensuring that processing accuracy is maintained through complete processing cycles while simultaneously preparing data for rapid subsequent shooting, thus achieving both processing accuracy and shooting speed.

AI summary
An image processing method and apparatus that minimizes a delay time until the image is detected and captured when shooting photographs where various shooting options (effects) are set. The image processing method includes displaying a preview in a shooting mode; receiving a shooting option based shooting command while displaying the preview; and processing image compensation applying a shooting option to an image having full resolution as a background, and substantially parallel operations, entering a preview mode to display a preview a display image.
