Recording Apparatus Data Conversion for Multipath Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image recording techniques face limitations in processing time due to the two-step conversion of original image data into dot data and subsequent division for each scanning line, which restricts the reduction of image degradation.
Innovation Solution
A recording apparatus with first and second recording element arrays, a multilevel data buffer, a reading unit, a production unit to generate binary data based on multilevel data and a code table, and a transferring unit to efficiently transfer binary data to corresponding recording element arrays, allowing for direct conversion of multilevel data into dot data for each pixel.

Engineering Contradiction Analysis
1Productivity
If the original image data is first converted into dot data and then the dot data is divided into data for each scanning line, then the image can be recorded using a multipath recording scheme, but the processing time cannot be reduced further
Solution Approach 1:
The patent merges the two separate conversion steps (original image data to dot data, then dot data division per scanning line) into a single integrated conversion process. The production unit directly generates binary data for multiple scanning lines simultaneously from the original image data, eliminating the intermediate dot data division step and reducing overall processing time.
Solution Approach 2:
The patent performs preliminary conversion of the original image data into binary data for multiple scanning lines before the actual recording process. By pre-converting the data in an efficient single-step process rather than sequentially through two steps, the system reduces processing time while maintaining recording quality.
2Manufacturing precision
If a two-step conversion process is used (original image data to dot data, then dot data division), then image quality can be maintained, but the processing time is increased
Solution Approach 1:
The patent combines multiple conversion operations into a single integrated process. The production unit directly converts original image data into binary data for multiple scanning lines simultaneously, merging what were previously two sequential steps into one efficient operation that maintains image quality while reducing processing time.
Solution Approach 2:
The patent ensures continuous and efficient data conversion by performing the conversion in a single uninterrupted process rather than through two separate steps. The production unit continuously generates binary data for multiple scanning lines from the original image data without intermediate pauses or transitions, maintaining both quality and speed.

AI summary
A recording apparatus is capable of forming an image on a recording medium by using a recording head including first and second recording element arrays for one color component wherein each recording element array includes a plurality of recording elements arranged therein. To perform, in a short time, processes including converting of multilevel data to binary data and assigning of the binary data to the recording element arrays, a multilevel data buffer stores multilevel data, a reading unit reads the multilevel data stored in the multilevel data buffer, and a production unit produces binary data from the multilevel data by using a code table including a plurality of code sets depending on a gray level wherein each code set includes codes corresponding to the first and second recording element arrays. A transferring unit transfers the binary data produced by the production unit to corresponding recording element arrays.
