Signal Processing Apparatus for Superimposing Enlarged Object Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signal processing apparatuses, such as video cameras, face difficulties in displaying the positional relationship of designated objects within a moving image due to limited functionality in enlarging and superimposing images.
Innovation Solution
A signal processing apparatus that includes an input unit, designation unit, detection unit, enlargement unit, superimposition unit, and controller to detect and superimpose enlarged images of designated objects, allowing for the generation of a single enlarged image when objects have a predetermined positional relationship, thereby enhancing the display of positional relations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only the function of obtaining the enlarged image of the designated object is used, then the enlarged image can be obtained, but the positional relation of the designated object to the whole original moving image cannot be grasped
Solution Approach 1:
The patent combines multiple functions into a single integrated system: object detection, motion vector calculation, image enlargement, and superimposition. The superimposition unit merges the enlarged image with the original moving image, allowing users to simultaneously view both the detailed enlarged view and the contextual positional relationship within the original scene.
Solution Approach 2:
The patent adds a new dimensional layer by superimposing the enlarged image over the original moving image. This creates a multi-layered display where the original image provides spatial context and the enlarged image provides detailed information, effectively adding an informational dimension without losing the original spatial relationships.
2Loss of information
If multiple enlarged images are generated for multiple objects, then detailed views of each object can be obtained, but the device complexity increases
Solution Approach 1:
The enlargement unit is designed as a universal processing module that can handle any number of detected objects through the same workflow. The system detects multiple objects, calculates motion vectors for each, generates enlarged images for each object, and superimposes them all using the same superimposition unit, thereby avoiding the need for separate dedicated processing paths for each object.
Solution Approach 2:
The system dynamically adjusts the number of enlarged images generated based on the number of objects detected in real-time. The superimposition unit dynamically manages the layering and positioning of multiple enlarged images, allowing the system to adapt its complexity to the actual scene requirements rather than being statically configured for a fixed number of objects.

AI summary
A signal processing apparatus for displaying an input image in the sate in which a part of the image is enlarged, displays an enlarged image obtained by enlarging a part of a designated object in the input image so that the enlarged image is superimposed at a position in accordance with the position of the designated object.
