Image capture method adapted to sparkling light sources and image sensor

A method comprising:

• processing images of a scene exposed with a flickering light, the processing comprising acquiring, during an integration period divided into a plurality of separate sub-periods, a value representative of a light level at a corresponding pixel for each of a plurality of pixels, the acquiring comprising
• gradually increasing a value of sensitivity of a corresponding photodiode of the corresponding pixel to a first value,
• maintaining the value of sensitivity of the corresponding photodiode at the first value after the gradual increase, and
• gradually decreasing the value of sensitivity of the corresponding photodiode from the first value to a second value, wherein the acquiring further comprises gradually increasing the value of sensitivity of the corresponding pixel by gradually decreasing a duration between each sub-period of the plurality of separate sub-periods, and gradually decrease the value of sensitivity of the corresponding pixel by gradually increasing the duration between each sub-period of the plurality of separate sub-periods.

A device comprising:

• a frequency detector to determine a frequency of a light source, wherein the device is configured to process images of a scene exposed with the light source, the processing comprising:
• acquiring, during an integration period divided into a plurality of separate sub-periods, a value representative of a light level at each pixel from a plurality of pixels by
• gradually increasing a value of sensitivity of a corresponding photodiode of the corresponding pixel to a first value,
• maintaining the value of sensitivity of the corresponding photodiode at the first value after the gradual increase, and
• gradually decreasing the value of sensitivity of the corresponding photodiode from the first value to a second value, wherein the device is further configured to gradually increase the value of sensitivity of the corresponding pixel by gradually decreasing a duration between each sub-period of the plurality of separate sub-periods, and gradually decrease the value of sensitivity of the corresponding pixel by gradually increasing the duration between each sub-period of the plurality of separate sub-periods.
