1Productivity
If multiple signal processing circuits are provided to perform parallel signal processing on divided image regions, then signal processing speed is improved, but control load increases due to the need to manage which signal processing is performed in each circuit
Solution Approach 1:
The image is divided into multiple regions, with each region assigned to a specific signal processing circuit for parallel processing. This segmentation enables simultaneous processing of different image regions by different circuits, improving overall signal processing speed while maintaining manageable control complexity through clear region-to-circuit mapping
Solution Approach 2:
An evaluation value generation unit is introduced as an intermediary that generates evaluation values based on image signals and provides them to signal processing circuits. This mediator enables centralized control of parallel processing operations, allowing the system to manage multiple circuits efficiently without proportionally increasing control load, as the evaluation values guide which processing operations each circuit should perform

If multiple signal processing circuits are provided for parallel processing, then processing capacity increases, but control complexity increases due to managing signal processing assignments across circuits
Solution Approach 1:
The evaluation value generation unit serves multiple signal processing circuits simultaneously, providing evaluation values that guide processing operations across all circuits. This multi-functional approach allows a single control unit to manage multiple circuits efficiently, increasing processing capacity without proportionally increasing control complexity
Solution Approach 2:
Evaluation values are generated as controllable parameters that dynamically adjust the operation of signal processing circuits. By changing these evaluation value parameters based on image content and processing requirements, the system can flexibly control multiple circuits' behavior, simplifying the management of parallel processing operations while maintaining high processing capacity
