INFORMATION PROCESSING DEVICE AND METHOD

The present disclosure relates to an information processing device and an information processing method capable of achieving code quantity control while securely retaining some of pixel values of sensing data.Whether or not each of pixel values of sensing data is a reserved word that is a predetermined value determined beforehand is determined. A flag map that indicates a position of a reserved word pixel that is a pixel having the reserved word as a pixel value and non-reserved word data that includes a pixel value of a non-reserved word pixel that is a pixel other than the reserved word pixel are generated. The generated flag map is subjected to lossless coding to generate a flag stream. The generated non-reserved word data is coded to generate a pixel stream. For example, the present disclosure is applicable to an information processing device, an image processing device, an electronic apparatus, an information processing method, an image processing method, a program, or the like.
