Solution Overview
Problem
Existing image processing technologies face challenges in accurately inspecting inspection objects using partial image data, as compressed image data can collapse characteristic portions, and peripheral inspections are not effectively executed with only partial data, leading to potential defects in detection accuracy.
Innovation Solution
An image processing apparatus and method that allows selection between compressed and partial image data for inspection, with the ability to generate partial image data that matches the aspect ratio and pixel count of the display screen, enabling accurate inspection without generating unnecessary data, and allowing switching between data types based on inspection conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If compressed image data is used for inspection, then arithmetic processing load is reduced, but characteristic portions may collapse and detection accuracy deteriorates
Solution Approach 1:
The system dynamically switches between compressed image data and partial image data based on inspection requirements. For general inspections, compressed data is used to reduce processing load. For inspections requiring high accuracy or peripheral inspection, the system switches to partial image data, enabling flexible adaptation to different inspection scenarios without being constrained by fixed data processing modes
Solution Approach 2:
The invention changes the parameter of image data representation by providing multiple formats (compressed vs. partial) and allowing selection between them. This parameter change enables the system to optimize between processing efficiency and detection accuracy by choosing the appropriate data format based on specific inspection needs
2Loss of time
If only partial image data is used for inspection, then processing time is reduced, but periphery inspection cannot be executed
Solution Approach 1:
The system dynamically adjusts the inspection scope and data type based on the required inspection type. For peripheral inspections, it switches to using partial image data that includes peripheral regions. For detailed inspections, it uses compressed full-image data. This dynamic adaptation allows the system to execute various inspection types efficiently without being limited by fixed processing modes
Solution Approach 2:
The invention creates a universal inspection system that can handle multiple inspection types (peripheral inspection, detailed inspection, general inspection) by providing a unified framework that selects appropriate image data formats based on inspection requirements, making the system versatile across different inspection scenarios
3Reliability
If full image data is processed, then comprehensive inspection is possible, but arithmetic processing load becomes excessively large
Solution Approach 1:
The system extracts only the necessary portion of image data for each inspection type. For peripheral inspections, it extracts peripheral regions. For detailed inspections, it extracts relevant areas from compressed data. This extraction approach maintains inspection completeness by selecting appropriate data portions while significantly reducing the arithmetic processing load compared to processing full-resolution images
Solution Approach 2:
The invention applies partial action by using partial image data for inspections that don't require complete image information. By using only the necessary portions of image data (peripheral regions for peripheral inspection, compressed data for general inspection), the system achieves sufficient inspection reliability without the excessive processing load of handling complete high-resolution images for all inspection types

AI summary
Provided is an image processing apparatus capable of viewing even a characteristic portion of an inspection object even if partial image data of the inspection object is used for inspection. The image processing apparatus includes an imaging portion for imaging an inspection object; a compression processing portion for executing compression processing on image data captured by the imaging portion, to generate compressed image data; and an image processing portion for executing image processing for an inspection. The image processing portion generates partial image data as part of the captured image data, and accepts a selection of any of the compressed image data and the partial image data as the image data for use in the image processing. The image processing portion executes the image processing for the inspection by use of the compressed image data or the partial image data, the selection of which has been accepted.
