Dot Layout Pattern Selection for Image Recording Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording methods fail to reliably select a suitable dot layout pattern for each region of an image, leading to inadequate resolution and noticeable streaks or unevenness, especially in images with varying focus and high-frequency components.
Innovation Solution
A recording control apparatus and method that utilize analysis information based on the distance to objects in an image to select a dot layout pattern for each pixel, incorporating a system with focus detection pixels and parallax images to generate tone value information for optimal dot placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single dot layout pattern is used for the entire image, then the device complexity is reduced, but the manufacturing precision deteriorates because high-resolution recording cannot be achieved in focused regions
Solution Approach 1:
The image is divided into multiple regions based on focus detection, and different dot layout patterns are assigned to different regions. This segmentation allows high-resolution recording in focused areas while using simpler patterns in out-of-focus areas, resolving the contradiction between recording precision and device complexity.
Solution Approach 2:
Different dot layout patterns are applied to different regions of the image according to their focus status. Focused regions receive patterns optimized for high resolution, while out-of-focus regions receive patterns optimized for robustness against mechanical variations, achieving local optimization of recording quality.
2Adaptability or versatility
If feature amount extraction is used to control dot layout, then adaptability to different image regions is improved, but reliability deteriorates when feature extraction fails
Solution Approach 1:
Focus detection serves as an intermediary mechanism that provides reliable depth information without requiring complex feature extraction. This intermediary approach maintains reliability while still enabling adaptability to different image regions based on their focus status.
Solution Approach 2:
The patent replaces complex feature extraction algorithms with a simpler focus detection mechanism that uses depth information from multiple focal planes. This substitution maintains adaptability while improving reliability by avoiding the pitfalls of feature extraction failures.
3Manufacturing precision
If high resolution is applied to the entire image, then manufacturing precision is improved, but loss of substance increases due to excessive ink usage in regions that do not require high resolution
Solution Approach 1:
High-resolution dot patterns are applied only to focused regions that require detail preservation, while out-of-focus regions use lower-resolution patterns. This local differentiation reduces overall ink consumption while maintaining necessary recording precision where it matters most.

AI summary
A recording control apparatus for recording a captured image obtains an image to be recorded and analysis information based on a distance to an object in each portion of the image. When causing a recording control unit to execute recording of the image, the recording control apparatus selects, on the basis of a value of each pixel of the image and the analysis information, a dot layout pattern that is used to record each pixel of the image and that indicates a layout of recorded dots included in dots constituting the pixel.
