Compensation techniques for diffraction patterns caused by an aperture of an image capture device

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 first image data from a camera comprising a variable aperture;
• determining a characteristic of the first image data correlated with a color temperature of the first image data;
• determining a compensation matrix based on whether the characteristic exceeds a predetermined threshold, wherein the compensation matrix comprises correction values for reducing one or more artifacts in the first image data resulting from blades of the variable aperture;
• and
• determining corrected image data based on the first image data and on the compensation matrix.

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

• receiving first image data from a camera comprising a variable aperture;
• determining a characteristic of the first image data correlated with a color temperature of the first image data;
• determining a compensation matrix based on whether the characteristic exceeds a predetermined threshold, wherein the compensation matrix comprises correction values for reducing one or more artifacts in the first image data resulting from blades of the variable aperture;
• and
• determining corrected image data based on the first image data and on the compensation matrix.

An image capture device, comprising:

• a sensor;
• a memory storing processor-readable code;
• and
• at least one processor coupled to the memory and to the sensor, the at least one processor configured to execute the processor-readable code to cause the at least one processor to perform operations including:
• receiving first image data from a camera comprising a variable aperture;
• receiving sensor data from the sensor regarding a scene represented by the first image data;
• determining a characteristic of the first image data based on the sensor data, wherein the characteristic is correlated with a color temperature of the first image data;
• determining a compensation matrix based on whether the characteristic exceeds a predetermined threshold, wherein the compensation matrix comprises correction values for reducing one or more artifacts in the first image data resulting from blades of the variable aperture;
• and
• determining corrected image data based on the first image data and on the compensation matrix.
