Abstract
Image encryption in which excessive concealment of information is prevented while reduction in cost is achieved by eliminating a need for a receiving side of an image to take measures against leakage of personal information is realized. In one example, a sensor device includes an array sensor with pixels having a light receiving element of visible or invisible light. A detector detects a target area on the basis of an image signal obtained by the array sensor. The target area in the image signal is encrypted on the basis of information from the detector. Thus, encryption of the image signal can be performed in the image sensor at least to the extent that no individual can be identified. Also, depending on a decryption key on a receiving side of the image, a part of the content of the image can be visually recognized while personal information is concealed.
