Image Processing Apparatus Zoom Control for Barcode Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems require lengthy processing times and high loads when capturing images of multiple objects, as they need to specify pan, tilt, and zoom operations individually for each object.
Innovation Solution
An image processing apparatus that divides the detection range into multiple areas, adjusts the zoom magnification, and controls the image capture direction for each area to sequentially generate images, reducing the need for frequent zoom and pan adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual pan, tilt, and zoom operations are specified for each object, then image capture accuracy is improved, but processing time increases
Solution Approach 1:
The detection range is divided into multiple divided areas, allowing the system to process multiple objects simultaneously through parallel operations rather than sequential individual operations for each object
Solution Approach 2:
The system performs preliminary image capture at a first zoom magnification to identify multiple objects and their positions before executing the actual data reading process, enabling optimized control instructions to be generated in advance
2Measurement precision
If zoom magnification is changed frequently for each object, then image capture precision is improved, but processing load increases
Solution Approach 1:
The detection range is segmented into divided areas that can be processed with uniform zoom magnification settings, reducing the need for frequent zoom changes while maintaining capture precision for multiple objects
Solution Approach 2:
Multiple image capture operations are merged into a single coordinated process where the image capturing apparatus executes pan, tilt, and zoom operations once to capture images of multiple divided areas simultaneously, rather than performing separate operations for each object

AI summary
An image processing apparatus that is capable of communicating with an image capturing apparatus, acquires a first image generated by performing an image capture process at a first zoom magnification, sets a division condition for dividing a detection range included in the first image, divides the detection range into a plurality of divided areas in accordance with the division condition, controls the image capturing apparatus to change an image capture direction on the basis of each position of the respective divided areas of the detection range and performs an image capture process at a second zoom magnification greater than the first zoom magnification so as to sequentially generate second images, acquires each of the second images, and performs a data reading process for each of the second images.
