Image processing for exposure bracketing

An apparatus, comprising:

• a memory storing processor-readable code;
• and
• at least one processor coupled to the memory, the at least one processor configured to execute the processor-readable code to cause the at least one processor to perform operations including:
• receiving, by the at least one processor, image data comprising first image data of a first exposure duration, second image data of a second exposure duration, and third image data of a third exposure duration, wherein:
• the first exposure duration is longer than the second exposure duration, and
• the third exposure duration is longer than the second exposure duration;
• determining, by the at least one processor, first summed image data by summing corresponding pixel intensity values of the first image data, the second image data, and the third image data;
• determining, by the at least one processor, second summed image data by summing corresponding pixel intensity values of the second image data and the third image data;
• and
• determining, by the at least one processor, a first output image frame by combining the first summed image data, the second summed image data, and the second image data.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• receiving, by at least one processor, image data comprising first image data of a first exposure duration, second image data of a second exposure duration, and third image data of a third exposure duration, wherein:
• the first exposure duration is longer than the second exposure duration, and
• the third exposure duration is longer than the second exposure duration;
• determining, by the at least one processor, first summed image data by summing corresponding pixel intensity values of the first image data, the second image data, and the third image data;
• determining, by the at least one processor, second summed image data by summing corresponding pixel intensity values of the second image data and the third image data;
• and
• determining, by the at least one processor, a first output image frame by combining the first summed image data, the second summed image data, and the second image data.

An image capture device, comprising:

• an image sensor;
• a memory storing processor-readable code;
• and
• at least one processor coupled to the memory and to the image sensor, the at least one processor configured to execute the processor-readable code to cause the at least one processor to perform operations comprising:
• receiving, by the at least one processor, image data comprising first image data of a first exposure duration, second image data of a second exposure duration, and third image data of a third exposure duration, wherein:
• the first exposure duration is longer than the second exposure duration, and
• the third exposure duration is longer than the second exposure duration;
• determining, by the at least one processor, first summed image data by summing corresponding pixel intensity values of the first image data, the second image data, and the third image data;
• determining, by the at least one processor, second summed image data by summing corresponding pixel intensity values of the second image data and the third image data;
• and
• determining, by the at least one processor, a first output image frame by combining the first summed image data, the second summed image data, and the second image data.
