Solution Overview
Problem
Existing image processing systems face challenges in efficiently performing multiple processes on images or video pictures due to the complexity of controlling execution sequences, which can affect the final result and complicate hardware circuit configurations.
Innovation Solution
An image processing device with a control section that can dynamically control the execution sequence of various image processing types, allowing for the execution or non-execution of processes and determining the sequence based on necessity, including processes like superimposing images and varying luminance according to in-plane distribution, to optimize the processing order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of image processing are performed on the processing target data, then the image processing capability is improved, but the control complexity of execution sequence increases
Solution Approach 1:
The patent implements dynamic execution sequence control where the control section adaptively determines the order of image processing operations based on the specific processing requirements. This allows the system to handle multiple image processing types (such as luminance adjustment, color correction, sharpness enhancement) with flexible sequencing, resolving the contradiction between enhanced processing capability and control complexity by making the sequence determination adaptive rather than fixed or manually configured for each case
2Ease of operation
If the execution sequence of image processing is fixed, then the control complexity is reduced, but the ability to achieve desired results in various cases is limited
Solution Approach 1:
The system employs dynamic execution sequence determination where the control section automatically adjusts the order of image processing operations based on the specific processing target data and required processing types. This dynamic approach maintains ease of operation by eliminating manual sequence configuration while simultaneously achieving high adaptability to various image processing scenarios and requirements
3Adaptability or versatility
If hardware circuit configuration is increased to handle multiple processing sequences, then the processing flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent implements a software-controlled dynamic sequencing mechanism where the control section determines the execution order of image processing operations through programmable logic rather than dedicated hardware circuits for each sequence. This approach achieves high processing flexibility by allowing dynamic reconfiguration of processing sequences while avoiding the complexity of multiple parallel hardware circuit paths, thereby resolving the contradiction between flexibility and circuit complexity

AI summary
A projector is configured so as to be able to perform a plurality of types of image processing on processing target data in the case in which one of still image data and data of a frame constituting video data is input as the processing target data. A video processing section includes a selector for controlling an execution sequence of the types of image processing to be executed, and a panel correction section for outputting the processing target data having been processed in the execution sequence controlled by the control section.
