Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image data is stored by a method suitable for a specific image output part, then the image output quality for that specific purpose is improved, but the versatility of the image data for other image output parts with different methods is reduced
Solution Approach 1:
The patent implements a data format conversion part that enables image data to be converted between different formats (such as CMYK and RGB). This allows the same image data to be used across multiple image output parts with different output methods, achieving multi-functionality and eliminating the need to store separate data for each output type.
Solution Approach 2:
The data format conversion part acts as an intermediary between the image data storage and various image output parts. It mediates the format differences between stored image data and the requirements of different output devices, enabling seamless conversion and compatibility without requiring separate storage for each output type.
2Device complexity
If simple alternating control between software and hardware is used, then the control complexity is reduced, but waiting periods are generated in both software and hardware sides reducing productivity
Solution Approach 1:
The patent introduces a buffer that temporarily stores image data before it is processed by the data format conversion part. This preliminary buffering allows the software and hardware to operate more independently, reducing the need for frequent synchronization and eliminating waiting periods while maintaining simple control logic.
Solution Approach 2:
The patent divides the image processing workflow into distinct segments: image data input, buffer storage, data format conversion, and image output. This segmentation allows each component to operate at its own pace with minimal interference from others, reducing synchronization overhead and improving overall throughput while keeping control complexity low.

AI summary
An image processing apparatus includes: an input part inputting image data; a storage part storing the input image data; an output part outputting the stored image data; a conversion part performing conversion on the output image data so that the data format thereof is converted to be suitable for the image output part; an SRC reservation part reserving, in the storage part, an SRC region of a capacity for storing the image data to be subjected to the conversion; a DST reservation part reserving, in the storage part, a DST region for storing the image data of the capacity after the conversion; a region division part dividing at least one of the SRC and DST regions into a plurality of regions; a first storing part storing the input image data in the SRC region; and a second storing part storing the image data after the conversion in the DST region.
