Patent ID: 8718409

Claim:
An apparatus comprising: a processor; and a memory coupled to the processor storing instructions that, when executed by the processor, cause the processor to perform operations comprising: selecting a pixel set including a first pixel and a second pixel based on pixel values and information on an image space of image data of a captured image; generating order information of the selected pixel set, wherein the order information includes at least information indicating a magnitude relationship between the first pixel and the second pixel; generating, verification data, by selecting the first pixel and the second pixel so that the order information is preserved via the change in the magnitude relationship; and outputting the image data and the verification data, wherein the selecting selects the first pixel and the second pixel where a distance between the first pixel and a center of a lens is greater than a distance between the second pixel and the center of the lens and a value of the first pixel is greater than a value of the second pixel.
