Abstract
A stereoscopic image-capturing apparatus includes a first digital image sensor, a second digital image sensor synchronized with the first sensor, at least one optical zoom with variable focal distance and associated with the first sensor or the second sensor, a digital zoomer for performing a digital zoom on a digital image coming from the second sensor, a resizer for choosing a resizing value to align an image to be aligned and coming from the first sensor and an image to be aligned and coming from the second sensor, and a depth map producer for producing a depth map.
Claims16
A stereoscopic image-capturing apparatus (10) comprising
- a first digital image sensor,
- a second digital image sensor synchronized with the first digital image sensor,
- at least one optical zoom with variable focal distance and associated with the first digital image sensor or the second digital image sensor,
- digital zoom means for performing a digital zoom on a digital image coming from the second digital image sensor, wherein
- the second digital image sensor is a monochromatic sensor and
- the first digital image sensor is a color sensor with a higher resolution than the monochromatic sensor,
- means for choosing a resizing value to align an image to be aligned and coming from the first digital image sensor and an image to be aligned and coming from the second digital image sensor, and
- means for producing a depth map associated with images captured on the same date by the first and second digital image sensors, using images coming from the second digital image sensor modified by the digital zoom means and resizing by the means for choosing a resizing value, wherein
- the means for choosing a resizing value is configured to be implemented at least when the focal distance of the optical zoom is modified, to calibrate the stereoscopic image-capturing apparatus,
- the means for choosing a resizing value is configured to be implemented when the stereoscopic image-capturing apparatus is turned on or reset, and
- the stereoscopic image-capturing apparatus is powered by an autonomous power source.
