Single DSP for Vehicle Camera Data Processing

The patent applies universality by configuring a single signal processor to perform multiple functions: it can process image data from the front camera for forward driving assistance functions, and also process image data from the reversing camera for reversing assistance functions. The signal processor is programmed with different programming codes that enable it to selectively activate processing for specific cameras based on the vehicle's operating state, thereby eliminating the need for separate dedicated signal processors for each camera while maintaining full processing capability.

The patent applies dynamics by making the signal processor's functionality dynamic rather than static. The signal processor selectively activates processing of specific camera inputs based on real-time vehicle operating conditions (forward driving vs. reversing). This dynamic reconfiguration allows one processor to adaptively serve multiple purposes, reducing the total number of processors needed while maintaining reliability for each specific function when required.

The patent reduces cost by making the signal processor universal. Instead of purchasing and installing separate signal processors for front camera processing and reversing camera processing, the system uses one programmable signal processor that can be configured via software (programming codes) to handle different camera inputs. This approach significantly reduces hardware costs while maintaining the ability to process image data from multiple cameras for different driver assistance functions.

The patent applies parameter changes by altering the operational parameters of the signal processor through different programming codes. The same physical processor can be programmed with different algorithms and configurations depending on which camera is active (front or reversing camera). This software-based parameter reconfiguration allows the system to maintain high processing capability for different functions without the cost of multiple dedicated hardware processors.

The patent applies periodic action by having the signal processor activate processing for only one camera at a time based on the vehicle's operating state. When the vehicle is moving forward, the processor periodically processes front camera data; when reversing, it periodically processes reversing camera data. This time-division approach prevents the processor from handling all cameras simultaneously, reducing the instantaneous processing load and energy consumption while still providing comprehensive coverage for different driving conditions.

The patent reduces processing load through dynamic reconfiguration. The signal processor dynamically switches between processing different camera inputs based on real-time vehicle state (forward or reverse). This dynamic behavior ensures that the processor is never overwhelmed by processing multiple camera streams simultaneously, as it selectively activates only the processing needed for the current operating condition, thereby managing energy consumption and processing load efficiently.
