Image Capturing Apparatus Command Processing Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image capturing apparatuses struggle to simultaneously perform wide dynamic range and digital dodging processes due to configuration constraints, leading to errors when receiving commands from external apparatuses for these processes over a network.
Innovation Solution
An image capturing apparatus with a control unit that selectively operates either the exposure setting unit or the synthesizing unit, allowing normal processing without error responses, and communicates with external apparatuses to transmit operation information based on received commands, enabling users to specify operations effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image capturing apparatus receives both synthesizing command and exposure setting command from external apparatus, then the apparatus should be able to process both commands, but the apparatus is incapable of simultaneously performing both wide dynamic range process and digital dodging process due to configuration constraints
Solution Approach 1:
The patent implements dynamic command management by determining whether to accept or reject commands based on current operational state. The control unit checks if a synthesizing command is already being executed before accepting an exposure setting command, and vice versa. This dynamic acceptance/rejection mechanism allows the system to adapt its command processing capability according to real-time configuration constraints without requiring complex hardware changes.
Solution Approach 2:
The system employs feedback mechanisms through determining units that continuously monitor the operational state of image processing functions. When a command is received, the control unit determines whether the apparatus can currently execute it based on ongoing processes. If the apparatus is already performing a synthesizing operation, it rejects exposure setting commands, and vice versa. This feedback loop ensures commands are processed only when configuration permits, preventing errors while maintaining versatility.
2Reliability
If the apparatus rejects commands it cannot process, then processing errors are prevented, but user convenience deteriorates due to error responses and limited option specification
Solution Approach 1:
The patent implements preliminary action by having the control unit proactively determine command acceptability before actual processing begins. When a command is received, the system immediately checks whether it can be executed given current operational state. If the check fails, the command is rejected with an error response before any processing occurs. This preliminary validation prevents processing errors while providing clear feedback to users about which operations are currently available, improving both reliability and ease of operation.

AI summary
An image capturing apparatus to communicate with an external apparatus includes an image capturing unit, a receiving unit, a control unit, a determining unit, and a transmitting unit. The receiving unit receives, from the external apparatus, a synthesizing command for controlling an operation of synthesizing images that have been captured by the image capturing unit under different exposure conditions, and an exposure setting command for controlling an operation of obtaining an image that has been generated under a set exposure condition. The control unit controls an operation that is performed based on the synthesizing and exposure setting commands, where the receiving unit receives the synthesizing and exposure setting commands. The transmitting unit transmits, to the external apparatus, operation information indicating operations which are specifiable by the synthesizing command and the exposure setting command received by the receiving unit, in accordance with a determination result obtained from the determining unit.
