IMAGE SIGNAL PROCESSING DEVICE AND OPERATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18321278 titled 'IMAGE SIGNAL PROCESSING DEVICE AND OPERATION METHOD THEREOF
Simplified Explanation
The operation method of an image signal processing device involves receiving a raw pixel code from an external image sensor device, generating a non-linear pixel code through non-linear mapping, and outputting a downsized pixel code obtained by masking operations on specific bit positions.
- Amplitude of the raw pixel code is linear to illuminance of light incident on the image pixel.
- Amplitude of the non-linear pixel code is non-linear to the amplitude of the raw pixel code.
- The downsized pixel code has a smaller code length compared to the non-linear pixel code.
Potential Applications
- Image processing in digital cameras
- Video processing in surveillance systems
- Medical imaging devices
Problems Solved
- Efficient image signal processing
- Improved image quality
- Reduction in data size for storage and transmission
Benefits
- Enhanced image processing capabilities
- Optimal use of image sensor data
- Reduced storage and bandwidth requirements
Original Abstract Submitted
An operation method of an image signal processing device includes receiving a raw pixel code from an external image sensor device including an image pixel, generating a non-linear pixel code by performing non-linear mapping on the raw pixel code, and outputting a downsized pixel code obtained by performing a masking operation on bit positions including a first bit position corresponding to a most significant bit of the non-linear pixel code and a second bit position corresponding to a least significant bit of the non-linear pixel code. An amplitude of the raw pixel code is linear to illuminance of a light incident onto the image pixel, an amplitude of the non-linear pixel code is non-linear to the amplitude of the raw pixel code, and the non-linear pixel code has a first code length, and the downsized pixel code has a second code length smaller than the first code length.
