Abstract
A method of operating a controller for processing image data includes receiving, from an image sensor, image data having successive frames and a signature value of the image data, and verifying the signature value using a vehicle speed. The verifying the signature value includes determining a checking period determined according to the vehicle speed, and verifying a signature value of a frame determined from among the successive frames according to the checking period.
Claims20
An operating method of a controller for processing image data, the method comprising:
- receiving, from an image sensor, image data having successive frames and a signature value of the image data;
- and
- verifying the signature value using a vehicle speed,
- wherein the verifying the signature value includes
- determining a checking period according to the vehicle speed, and
- verifying a signature value of a frame determined from among the successive frames according to the checking period.
A controller for processing image data, the controller comprising:
- a memory storing a program of instructions;
- and
- a processor configured to execute the program of instructions to
- receive speed information from an external sensor and to determine a vehicle speed based on the speed information,
- determine an integrity checking period corresponding to the vehicle speed, and
- verify integrity of a frame received from an image sensor according to the integrity checking period.
An image processing system, comprising:
- an image sensor configured to
- acquire image data,
- generate a signature value corresponding to the image data, and
- output the image data and the signature value as secured image data via a first communication interface;
- and
- a controller configured to
- receive the secured image data from the image sensor, and
- verify the signature value according to a checking period corresponding to a vehicle speed.
