Abstract
To provide an image sensor capable of guaranteeing consistency between acquired image information and picked-up image information. An image sensor 30 includes an image information processing unit 4 that forms integrated information in which image sensor identification information capable of identifying the image sensor 30 and image information obtained by an analog/digital conversion unit 25 are associated with each other, and an image information output unit 24 that outputs the integrated information to an external unit.
Claims19
An image sensor, at least comprising:
- an image information processing unit that forms integrated information in which image sensor identification information capable of identifying the image sensor and image information obtained by an analog/digital conversion unit are associated with each other;
- and
- an image information output unit that outputs the integrated information to an external unit.
An image pickup apparatus, at least comprising
- an image sensor including
- an image information processing unit that forms integrated information in which image sensor identification information capable of identifying the image sensor and image information obtained by an analog/digital conversion unit are associated with each other, and
- an image information output unit that outputs the integrated information to an external unit.
An image sensor-identifying method, comprising
- identifying an image sensor by analyzing integrated information in which image sensor identification information capable of identifying the image sensor and image information obtained by an analog/digital conversion unit are associated with each other, the integrated information being output from the image sensor to an external unit.
An image forgery-preventing method, comprising
- preventing forgery of image information by using electronic signature information in which image sensor identification information capable of identifying an image sensor and image information obtained by an analog/digital conversion unit are associated with each other and are encrypted, the electronic signature information being output from the image sensor to an external unit.
An image alternation-limiting method, comprising
- giving an image alternation privilege only to decrypted image information obtained by performing decryption processing on image information including electronic signature information in which image sensor identification information capable of identifying an image sensor and the image information obtained by an analog/digital conversion unit are associated with each other and are encrypted, the image information being output from the image sensor to an external unit.
