Abstract
Disclosed is an image sensor, an image processing system including the image sensor, and an operating method of the image processing system, the image sensor including a first detection circuit configured to detect an eye region of a user from an information image obtained by capturing an image of the user, a first probability map generation circuit configured to generate a first probability map which corresponds to a direction in which the user's eyes gaze, based on the eye region, and a storage circuit configured to store the first probability map.
Claims17
An image processing system comprising:
- a first image sensor configured to perform at least one function on a region of interest, which a user gazes at, based on setting information, and obtain a captured image including the region of interest in a normal mode;
- a second image sensor configured to generate a first probability map which corresponds to a direction in which the user's eyes gaze, based on an information image obtained by capturing an image of the user in a low power mode having a lower resolution and lower frame rate than a resolution and frame rate used in the normal mode;
- and
- an image processor configured to detect the region of interest based on the captured image received from the first image sensor and the first probability map received from the second image sensor, and adjust the setting information based on the region of interest.
An operating method of an image processing system having a front camera, a rear camera, and an image processor, the operating method comprising:
- enabling the rear camera in a normal mode and enabling the front camera in a low power mode having a lower resolution and lower frame rate than a resolution and frame rate used in the normal mode;
- capturing, by the front camera, an image of a user in the normal mode, and generating a first probability map representing a direction in which the user's eyes gaze;
- detecting, by the image processor, a region of interest which the user's eyes gaze at, based on the first probability map;
- adjusting, by the image processor, setting information corresponding to the region of interest;
- and
- performing, by the rear camera, at least one function on the region of interest based on the setting information, and obtaining a captured image including the region of interest.
