Colour-Separation/Tonal-Correction TRIZ Cases
- Inclined Backing Surface for Image Reading Edge Detection
An image reading apparatus uses an inclined backing surface to form a prominent shadow on the medium.
- Image Reading Apparatus Shading Correction via Color Ratio Analysis
A ratio calculator determines white level information ratios among colors to identify and replace abnormal data in image reading apparatuses.
- Bi-directional Printing Color Tone Consistency via Directional Gamma Adjustment
A print data generating apparatus adjusts color component values using a specific color conversion profile for bi-directional printing.
- Color Patch Generation Apparatus for Efficient RGB and Lab Measurement
A color patch generation apparatus prints distinct RGB and Lab patches on a single sheet to streamline the measurement process.
- Scanner CIS Heat Management via Frequent Black Reference Data
Frequent black reference data acquisition compensates for temperature drift in the CIS module, maintaining image quality without extending processing time.
- Image Conversion Simulation System for Inkjet Process Deviation
Software system simulates inkjet imaging by tracking individual picture element transformations and recording physical state changes.
- Printer Terminal Preview Data Layout Generation
Terminal device receives layout data from the printer to generate accurate preview images, reducing processing load and ensuring consistency.
- Monochrome Image Density Control for Color Emphasis
System detects low-density color materials and modifies output density parameters to improve printed legibility without emphasizing notes or stains.
- Color Printing System Dynamic Adjustment Using Document Data
A color printing system specifies areas with predetermined colors from image data to measure and adjust output.
- White Reference Member Posture Control for Shading Accuracy
A white reference member attached to a cover uses a driving unit to switch between operating and non-operating postures.
- Image Reading Smear Correction via Reference Data
An image processing unit applies brightness correction using stored reference smear amount data for each color component.
- Color Patch Allocation for Printer Calibration
A test chart method determines patch counts per color based on colorimetric variation to optimize calibration.
- Copying Apparatus Color Detection Image Adjustment
A copying apparatus detects color images to trigger image adjustment marks only when needed.
- Pitch-to-Pitch Gray Balance Calibration via Margin TRCs
Individual pitch tone reproduction curves compensate for pigment variations to maintain gray balance without interrupting production.
- Spot Color Printing via Colored Substrates
Colored substrates replace spot color inks, eliminating frequent ink changes and simplifying short-run printing operations.
- Color Adjusting Apparatus for Optical Scan Modules
A color adjusting apparatus uses reflectors or colored plating films on lenses to enhance specific light intensities.
- Image Reading Device Dual-Side Ground Color Correction
A dual-sensor image reading device applies coordinated ground color corrections to document faces using density value comparisons.
- Image Reading Apparatus with Multi-Spectral Detection for Wrinkle Correction
Multi-spectral detection units compare outputs against stored characteristics to detect paper wrinkles and correct color components.
