Image processing device
An image processing device includes: a measuring unit that measures a light quantity; an identification unit that identifies a region within an image-capturing range using the measured light quantity, the region having a light quantity higher than or equal to a predetermined light quantity; a setting unit that sets an image-capturing angle so that the identified region is out of the image-capturing range; and an image-capturing unit that captures an image for authentication at the image-capturing angle set by the setting unit.
1. An image processing device comprising:
a light quantity sensor;
an image sensor; and
a controller configured to:
identify a region within an image-capturing range using a measured light quantity from the light quantity sensor, the region having a light quantity higher than or equal to a predetermined light quantity;
set an image-capturing angle so that the identified region is out of the image-capturing range; and
control the image sensor to capture an image for authentication at the image-capturing angle set by the controller so that the region having the light quantity higher than or equal to the predetermined light quantity is excluded from the image for authentication.
2. The image processing device according to claim 1 , wherein the light quantity sensor and the image sensor are a same sensor.
3. The image processing device according to claim 1 , wherein the light quantity sensor and the image sensor are a different sensor.
4. An image processing device comprising:
a light quantity sensor;
an image sensor; and
a controller configured to:
identify a region within an image-capturing range using a measured light quantity from the light quantity sensor, the region having a light quantity higher than or equal to a predetermined light quantity;
identify a position of a subject so that the region is hidden, and present an image-capturing position of the subject according to the position of the subject so that the subject is away from the region having the light quantity higher than or equal to the predetermined light quantity; and
control the image sensor to capture an image for authentication after the image-capturing position is presented so that the region having the light quantity higher than or equal to the predetermined light quantity is not in the image for authentication.
5. The image processing device according to claim 4 , wherein the light quantity sensor and the image sensor are a same sensor.
6. The image processing device according to claim 4 , wherein the light quantity sensor and the image sensor are a different sensor.
