Image Sensor Region Information Embedding for DSP Control Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing systems face increased processing burdens when handling partial regions of image data, particularly in enhancing image quality and frame rate, due to limited header information and complex control requirements for dynamic readout and display regions.
Innovation Solution
An image capturing apparatus and method that adds additional region information to image data, allowing for efficient transmission and processing of specified pixel regions, reducing the processing burden by enabling the extraction and processing of specific regions within the image data without the need for complex control mechanisms.

Engineering Contradiction Analysis
1Productivity
If separate control of the DSP by the control unit is implemented to perform processing on the readout region, then image quality enhancing and frame rate enhancing can be achieved, but the processing burden of the DSP increases and control becomes more complicated
Solution Approach 1:
The patent applies preliminary action by adding region information (first region information specifying the readout region and second region information specifying the display region) to the header of image data at the image sensor level before transmission to the DSP. This allows the DSP to autonomously determine and process the required regions without requiring complex control signals from the control unit, thereby reducing control complexity while maintaining enhanced frame rate capability
Solution Approach 2:
The patent enables self-service by equipping the DSP with the capability to independently process image data using the region information embedded in the data stream. The DSP can autonomously extract and process the display region from the readout region based on the embedded region information, eliminating the need for complex external control and reducing the processing burden on the control unit
