High dynamic range imaging method and imaging system

An imaging system, comprising:

• an image sensor, configured to capture a plurality of first images in a photographed region;
• a processing module, configured to determine a target region based on the plurality of first images, wherein the target region is a part of the photographed region, and luminance of the target region meets a threshold;
• and
• a modulation module, configured to modulate an optical signal from the photographed region, to attenuate light intensity of an optical signal from the target region, wherein
• the image sensor is further configured to capture a second image in the photographed region based on a modulated optical signal.

A camera lens, comprising:

• an image sensor, configured to capture a plurality of first images in a photographed region;
• a processing module, configured to determine a target region based on the plurality of first images, wherein the target region is a part of the photographed region, and luminance of the target region meets a threshold;
• and
• a modulation module, configured to modulate an optical signal from the photographed region, to attenuate light intensity of an optical signal from the target region, wherein
• the image sensor is further configured to capture a second image in the photographed region based on a modulated optical signal.
