Abstract
An image processing system includes an image sensor suitable for performing an operation in a first mode to generate an image of a first quality and performing an operation in a second mode to generate an image of a second quality which is higher than the first quality; an auxiliary processor suitable for processing the image of the first quality generated by the image sensor in the first mode; and a main processor suitable for processing the image of the second quality generated by the image sensor in the second mode.
Claims23
An image processing system, comprising:
- an image sensor suitable for performing an operation in a first mode to generate an image of a first quality and performing an operation in a second mode to generate an image of a second quality which is higher than the first quality;
- an auxiliary processor suitable for processing the image of the first quality generated by the image sensor in the first mode;
- and
- a main processor suitable for processing the image of the second quality generated by the image sensor in the second mode.
An image processing system, comprising:
- an image sensor suitable for performing an operation in a first mode to generate an image of a first quality and performing an operation in a second mode to generate an image of a second quality which is higher than the first quality;
- and
- a processor suitable for processing an image generated by the image sensor,
- wherein the processor consumes more current in the second mode than in the first mode, and
- wherein when a presence of a face is detected as a result of processing the image of the first quality which is generated by the image sensor in the first mode, an operation mode of the image sensor is switched from the first mode to the second mode.
An image processing system, comprising:
- an image sensor suitable for performing an operation in a first mode to generate an image of a first quality and performing an operation in a second mode to generate an image of a second quality which is higher than the first quality;
- and
- a processor suitable for processing an image generated by the image sensor,
- wherein the processor consumes more current in the second mode than in the first mode, and
- wherein when a presence of a gesture is detected as a result of processing the image of the first quality which is generated by the image sensor in the first mode, an operation mode of the image sensor is switched from the first mode to the second mode.
A method for recognizing a face or gesture in an image processing system, the method comprising,
- identifying a presence of a face or gesture based on an image generated by an image sensor in a first mode;
- switching the image processing system from the first mode to a second mode, when the identifying operation is successful;
- authenticating an identification of the face or recognizing one of predetermined gestures based on an image generated by the image sensor in the second mode;
- and
- unlocking the image processing system when the authenticating or recognizing operation is successful,
- wherein a current consumption used for generating the image in the first mode is lower than that used for generating the image in the second mode.
