Imaging Device Automatic Exposure Color Correction Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices require users to switch between screens to correct exposure and color variations, making the process complicated and cumbersome, especially when exposure correction darkens the image, necessitating subsequent color adjustments.
Innovation Solution
An imaging device with a display that includes a first corrector for exposure parameters and a second corrector for image processing parameters, along with an automatic correction controller to determine and apply color corrections simultaneously with exposure adjustments on the same screen, using gain coefficients for red and blue components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If exposure correction is applied to darken the image, then the exposure parameter is corrected, but the color of the image becomes bluish requiring additional color correction
Solution Approach 1:
The patent combines exposure correction and color correction functions into a single integrated operation. When the user adjusts exposure correction amount, the system automatically performs both exposure correction and color correction simultaneously, merging two separate adjustment processes into one unified operation that occurs on a single screen without requiring screen switching.
Solution Approach 2:
The system automatically performs color correction without user intervention by calculating the appropriate color correction amount based on the exposure correction amount. The automatic correction controller determines and applies color correction automatically, allowing the system to serve itself rather than requiring the user to manually adjust color parameters after exposure correction.
2Illumination intensity
If exposure correction is applied, then the exposure parameter is corrected, but the user must switch screens to adjust color, increasing operational steps
Solution Approach 1:
The patent combines exposure correction and color correction functions into a single integrated operation. When the user adjusts exposure correction amount, the system automatically performs both exposure correction and color correction simultaneously, merging two separate adjustment processes into one unified operation that occurs on a single screen without requiring screen switching.
Solution Approach 2:
The system performs color correction in advance as part of the exposure correction process. By calculating and applying the appropriate color correction amount based on the exposure correction amount before the user completes their adjustment, the system eliminates the need for subsequent separate color adjustment steps.
3Device complexity
If uniform exposure correction range and units are used, then the correction settings are simple, but the correction cannot be performed in an optimal range for different photographic scenes
Solution Approach 1:
The patent implements dynamic adjustment of correction parameters based on photographic scene characteristics. The system automatically determines the appropriate correction range and units by analyzing the captured image's brightness distribution and scene properties, allowing the correction settings to adapt dynamically to different shooting conditions while maintaining simple user interaction.
Solution Approach 2:
The system changes correction parameters (range and units) based on the photographic scene and image characteristics. By automatically adjusting these parameters according to the captured image properties, the system achieves optimal correction performance for different scenes without requiring complex manual configuration from the user.

AI summary
An imaging device includes a display on which a captured image of a subject is displayed, a first corrector to correct a first parameter related to shooting of the subject, a second corrector to correct a second parameter related to image processing to the captured image, and an automatic correction controller to determine a correction amount for the second parameter on the basis of a correction amount for the first parameter corrected by the first corrector, and control the second corrector to correct the second parameter by the determined correction amount.
