Abstract
This camera is formed by a sensor (3) composed of elements sensitive to various color components in the view exhibiting an entire spectrum of spatial frequencies, and at least a first image filtering device (10) for the low frequencies in the spectrum with a view to processing the signals issuing from said sensitive elements. This apparatus is in essence formed by a first branch (B1) in which said first filtering device (10) and by a second branch (B2) in which a second filtering device (12) is inserted for the high frequencies of the spectrum in order to filter all the signals issuing from said elements and a combination device for supplying an image taking account of the output signals of said branches. In this manner a good sharpness of the image is obtained.
Claims3
A camera formed by a sensor composed of elements sensitive to various color components in the view exhibiting an entire spectrum of spatial frequencies, and at least a first image filtering device for the low frequencies in the spectrum with a view to processing the signals issuing from said sensitive elements, characterized in that it has a first branch in which said first filtering device is inserted, at least a second branch in which a second filtering device is inserted for the high frequencies of the spectrum in order to filter all the signals issuing from said elements and a combination device for supplying an image taking account of the output signals of said branches.
A photographing method, characterized in that it includes the following steps:
- impression of the sensor composed of elements sensitive to the various color components of the view,
- processing the information from this sensor by a first processing branch operating on the color-sensitive elements,
- processing the information from this sensor by a second processing branch operating on all the elements without taking account of the color and operating on the upper part of the spatial spectrum,
- combination of the various items of information produced by said branches in order to supply an image for use.
