Image Processor Chip Appending Data to Prevent Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing technologies on portable terminals face issues with displaying images properly due to insufficient appended data, leading to loss of image data, especially with increasing pixel counts and decreasing sensor sizes, resulting in incomplete or distorted images.
Innovation Solution
An image processor chip that adds appended data to the raw data from an image sensor before processing, specifically by inputting additional pixel data at the beginning and end of each line or frame, to ensure complete data reproduction and prevent image distortion during interpolation and filtering.

Engineering Contradiction Analysis
1Productivity
If image processing is performed on raw data from small or thin image sensors with increasing pixel counts, then image processing capability is improved, but image data loss occurs due to insufficient appended data
Solution Approach 1:
The patent applies preliminary action by adding appended data to the raw image data before it enters the image processing unit. This pre-preparation of additional pixel data ensures that when interpolation and filtering operations are performed, the necessary data is already available, preventing data loss during processing. The control unit adds this supplemental data in advance based on the sensor's pixel arrangement and processing requirements.
2Reliability
If appended data is added to raw data before processing, then image data completeness is improved, but device complexity increases
Solution Approach 1:
The control unit in the patent performs multiple functions: it manages data flow from the image sensor, determines the appropriate appended data to add based on the sensor characteristics and processing requirements, and outputs the complete data stream to the image processing unit. This multi-functional approach consolidates what would otherwise require separate components, managing the increased complexity through functional integration rather than adding separate hardware blocks.

AI summary
A method and an apparatus for outputting pixel data with appended data are disclosed. An imaging device in accordance with an embodiment of the present invention includes an image sensor, which outputs raw data corresponding to an external image, a memory, which stores the raw data inputted from the image sensor; an output control unit, which adds appended data to the raw data stored in the memory and outputs the added raw data, and an image signal processor, which performs image processing corresponding to at least one of filtering and interpolation of the raw data or the raw data to which the appended data are added. With the present invention, a loss of image data to be displayed can be prevented.
