Limited luminance motion blur reduction

An image capture apparatus comprising:

• a non-transitory computer-readable medium;
• and
• a processor configured to execute instructions stored on the non-transitory computer-readable medium to:
• obtain, by a target exposure component of an image capture apparatus, a target gain value and a target exposure duration value, wherein, to obtain the target gain value and the target exposure duration value, the processor is configured to execute the instructions to:
• obtain a current scene luminance value;
• obtain a current maximum gain in accordance with the current scene luminance value;
• obtain a current interpolated gain-exposure duration curve in accordance with the current maximum gain and a current angular speed value;
• and
• obtain the target gain value and the target exposure duration value from the current interpolated gain-exposure duration curve in accordance with a current maximum exposure duration;
• obtain a frame of a video in accordance with the target gain value and the target exposure duration value;
• and
• output the video.

A non-transitory computer-readable storage medium having stored thereon executable instructions that, when executed by one or more processors of an image capture apparatus, cause the image capture apparatus to:

• obtain, by a target exposure component of the image capture apparatus, first target scene exposition data including a first target exposure duration value and a first target sensor gain value;
• access, by the target exposure component, a first input frame of a video captured by an image sensor of the image capture apparatus in accordance with a defined frame rate, an adaptive acquisition control sample rate that is one third of the defined frame rate, and the first target scene exposition data;
• obtain, by the target exposure component, in accordance with the first target scene exposition data and the first input frame, second target scene exposition data including a second target exposure duration value and a second target sensor gain value, wherein to obtain the second target scene exposition data the executable instructions include instructions that, when executed by the one or more processors, cause the image capture apparatus to:
• obtain a current scene luminance value in accordance with the first input frame;
• obtain a current maximum gain using the current scene luminance value;
• obtain a current interpolated gain-exposure duration curve using the current maximum gain and angular speed data corresponding to capturing the first input frame;
• and
• obtain the second target sensor gain value and the second target exposure duration value from the current interpolated gain-exposure duration curve in accordance with a current maximum exposure duration;
• and
• access, by the target exposure component, a second input frame of the video captured by the image sensor of the image capture apparatus in accordance with the defined frame rate, the second target exposure duration value, and the second target sensor gain value.
