Abstract:
1. A digital image-taking apparatus comprising an optical lens and an image sensor adapted to an implementation of a method of detecting objects in a digital image comprising the steps of: acquiring, by means of a digital image-taking apparatus, a digital image with aberration of a scene, said digital image incorporating at least a first image zone and a second image zone, the first and second image zones having respectively at least a first resolution and at least a second resolution, said first and second resolutions being different; calculating a deployed digital image, by deployment of at least one zone of said digital image with aberration; applying an object detection algorithm in said deployed digital image; and supplying information on each object detected in said deployed digital image; wherein said image sensor comprises a plurality of pixels distributed over at least one central pixel zone having a first pitch between any two adjacent pixels in said central pixel zone and at least one edge pixel zone having a second pitch between any two adjacent pixels in said second edge pixel zone, said first and second pitches having different values, said first pitch being greater than the said second pitch, and said central and edge pixel zones corresponding respectively to said first and second image zones; wherein said digital image-taking apparatus comprises an infrared filter disposed at the level of an image plane or an intermediate image plane of said digital image-taking apparatus; wherein said infrared filter comprises at least two zones in which distinct filterings are provided, a first zone corresponding to the top part of the image, and in which the infrared rays undergo substantially no filtering and a second zone corresponding to the bottom part of the image and in which the infrared rays are filtered substantially in their entirety.
