Image Processing Apparatus Isolating Color Parameter Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in confirming the effects of adjusting image quality parameters in RAW images, as changes in color processing parameters are masked by changes in image size parameters, making it hard to distinguish between the impact of each parameter on the final image quality.
Innovation Solution
An image processing apparatus and method that separately adjusts and displays the effects of pixel number and image quality parameters, allowing users to generate and compare images processed with different parameter settings, thereby isolating the impact of each parameter on the image quality.

Engineering Contradiction Analysis
1Productivity
If the user adjusts both color processing parameters and image size parameters simultaneously, then the developing process can be completed efficiently, but it becomes difficult to distinguish the individual effects of each parameter on image quality
Solution Approach 1:
The patent segments the developing process into two distinct modes: a comparison mode that isolates color processing parameter effects by maintaining constant image size, and a normal mode that allows simultaneous adjustment of both parameters. This segmentation enables users to separately evaluate color processing effects without the confounding influence of resizing operations.
Solution Approach 2:
The patent extracts the color processing parameter adjustment from the simultaneous parameter adjustment context by providing a dedicated comparison mode where only color processing parameters change while image size parameters remain fixed. This extraction allows users to observe purely the color processing effects on image quality.
2Manufacturing precision
If the image capturing apparatus processes high-resolution RAW images in real-time, then the image quality can be maintained, but the processing time increases significantly
Solution Approach 1:
The patent implements preview image generation that processes only a subset of pixels from the full-resolution RAW image. By selecting and processing fewer pixels than the complete image set, the system provides a timely preview that suffices for user evaluation, accepting partial processing in exchange for reduced processing time.
3Speed
If the resizing process is applied to reduce pixel numbers, then the processing speed increases, but the color accuracy may be affected due to interpolation processing
Solution Approach 1:
The patent introduces a comparison mode that acts as an intermediary evaluation environment where color processing parameters are tested without subsequent resizing operations. This intermediary mode eliminates the confounding effect of interpolation-based resizing on color accuracy, allowing users to evaluate color processing effects on the original high-resolution image data.

AI summary
There is provided an image processing apparatus. An obtainment unit obtains a first parameter pertaining to a number of pixels and a second parameter pertaining to image quality aside from the number of pixels. A changing unit instructs the first parameter and the second parameter to be changed. An image processing unit generates a first image by carrying out image processing on an original image in accordance with the changed first parameter and the changed second parameter, and generates a second image in accordance with the changed first parameter and the second parameter before the change. A display control unit displays the first and second images. A recording control unit carries out control such that an image generated by carrying out the image processing on the original image in accordance with the changed first parameter and the changed second parameter is recorded.
