Abstract
An electronic apparatus is configured to include an area sensor with a rolling shutter method and a detector configured to detect a change in a position of the area sensor, based on an inter-frame difference for each line in an image captured by the area sensor.
Claims6
An electronic apparatus comprising:
- a first area sensor with a rolling shutter method;
- a second area sensor with a rolling shutter method;
- and
- a detector configured to detect each of a change in a position of the first area sensor, based on an inter-frame difference for each line in an image captured by the first area sensor, and a change in a position of the second area sensor, based on an inter-frame difference for each line in an image captured by the second area sensor,
- wherein the first area sensor and the second area sensor are disposed in respective positions so as to image a same subject,
- the first area sensor is fixed to a housing,
- the second area sensor is fixed to the housing and has a main scanning direction coinciding with a direction orthogonal to a main scanning direction of the first area sensor, and
- the detector detects a change in a position of the housing in the main scanning direction of the first area sensor, based on the image captured by the first area sensor, and detects the change in the position of the housing in the main scanning direction of the second area sensor, based on the image captured by the second area sensor.
