Image Processing Apparatus Automatic Color Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating images with a specific impressive color require complicated user operations and fail to automatically maintain the desired color when environmental changes occur.
Innovation Solution
An image processing apparatus that automatically identifies and maintains the color of a designated object as chromatic by dividing the image into regions, calculating evaluation values, and applying a color conversion process to keep the characteristic object's color while changing others to achromatic.

1Extent of automation
If a user designates a desired color and only that color is kept as chromatic while other colors are changed to achromatic, then an image with a specific impressive color is generated, but complicated user operations are required such as setting a frame
Solution Approach 1:
The system automatically performs color selection and frame setting without user intervention. The control unit autonomously identifies the subject region, determines the impressive color within that region, and applies color conversion, eliminating the need for users to manually set frames or select colors.
Solution Approach 2:
The system changes the operational parameters from manual user-defined values to automatically calculated values. The frame position, size, and color selection parameters are dynamically adjusted based on subject detection results and color analysis, rather than requiring fixed user input.
2Measurement precision
If a user sets a frame to determine the desired color, then the color selection is precise, but the operation becomes complicated and time-consuming
Solution Approach 1:
The system performs subject detection and frame determination in advance before color selection. By pre-identifying the subject region automatically, the system eliminates the need for users to spend time setting frames, while still achieving precise color selection within the predetermined subject region.
Solution Approach 2:
The manual mechanical operation of drawing and adjusting a frame is replaced with an automated digital detection system. The control unit uses image processing algorithms to automatically identify subject boundaries and determine the appropriate region for color analysis, substituting user manual operations with computational processes.
3Stability of the object's composition
If the user confirms the color to be kept at a certain time point, then the color selection is fixed, but environmental changes after confirmation cause incorrect color keeping
Solution Approach 1:
The system transitions from a static color selection approach to a dynamic one. Instead of fixing the color selection at one time point, the system continuously or periodically re-evaluates the impressive color in the subject region, allowing it to adapt to environmental changes such as lighting conditions while maintaining stability through consistent subject-based selection.
Solution Approach 2:
The system implements a feedback mechanism where the color selection is continuously monitored and adjusted based on current image data. By repeatedly analyzing the subject region and updating the impressive color determination, the system provides feedback that corrects for environmental changes, ensuring the kept color remains accurate and meaningful.

AI summary
The present invention enables automatic generation of an image in which only an impressive color is kept, without requiring a complicated operation. A digital camera 100 divides an image obtained by an imaging unit 20 into regions based on color information and luminance information, and determines a characteristic object in accordance with a characteristic degree of each region into which the image is divided. Further, a region for keeping a color is set in which the color of the characteristic object is to be kept. A color conversion process is then performed so as to keep the color of the characteristic object in the region for keeping a color, and to change colors of the other regions to an achromatic color.
