Abstract

A method, system, and computer program product of encoding a digital image comprising a privacy mask. Information representative of pixels in the digital image is received. The pixels are grouped into encoding units. Information representative of a privacy mask area in which a privacy mask is to be applied on the image is also received. All encoding units that at least partially are located within the privacy mask area are identified, and the privacy mask area is extended to be aligned with the identified encoding units. For each encoding unit, a respective quantization parameter to be used for encoding the image is determined. The privacy mask is applied in the extended privacy mask area of the image, and the image with the applied privacy mask is encoded using the determined quantization parameters. The digital image encoding system may be included in a camera.
