Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging readers face inefficiencies in converting monochrome output data streams from monochrome imagers to color formats required by color controllers, leading to sluggish reading performance due to the use of dummy data.
Innovation Solution
A converter circuit that formats the monochrome data stream to include additional slots for auxiliary pixel data, which contains useful information, eliminating the need for dummy data and enhancing the reading performance by processing both pixel and auxiliary data to generate a compatible color format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dummy data is used to convert monochrome format to color format, then compatibility with color controller is achieved, but reading performance becomes sluggish
Solution Approach 1:
The patent extracts and removes the dummy data portion from the data stream conversion process. Instead of inserting dummy color data into the monochrome output, the system selectively extracts only the necessary luminance information and uses it to generate meaningful color data through processing, thereby eliminating useless dummy data while maintaining compatibility
Solution Approach 2:
The patent introduces an intermediary processing stage between the monochrome imager and color controller. This intermediary converter circuit processes the monochrome luminance data through algorithms that generate meaningful color information, serving as a mediator that transforms the data format without requiring dummy data, thus improving reading performance while maintaining compatibility
2Measurement precision
If monochrome imager is used, then signal-to-noise ratio and light sensitivity are improved, but format compatibility with color controller is lost
Solution Approach 1:
The patent applies parameter changes by transforming the data stream parameters from monochrome luminance values to color space representations. The converter circuit processes the luminance data and generates color information by modifying the data parameters, allowing the monochrome imager's high-quality luminance data to be compatible with color controller requirements without sacrificing measurement precision
Solution Approach 2:
The patent achieves universality by creating a converter circuit that serves multiple functions: it maintains compatibility with color controllers while preserving the high signal-to-noise ratio of monochrome imagers. The system makes the monochrome imager universally compatible with color processing requirements through intelligent data transformation rather than requiring dummy data
Data Source
AI summary
An apparatus and method read a target by capturing return light from the target with a solid-state monochrome imager operative for generating an output data stream in a monochrome format having a plurality of slots containing pixel data indicative of an image of the target, and with a color controller for receiving the output data stream in a color format different from the monochrome format. A converter circuit converts the monochrome format into the color format and includes an input formatter for formatting the output data stream to have additional slots, a buffer for receiving auxiliary pixel data related to the image of the target, and an output formatter for inserting the auxiliary pixel data from the buffer into the additional slots and for processing both the pixel data and the auxiliary pixel data to enhance the reading of the target.
