Abstract: A camera is in the form of a sensor (3) composed of light-sensitive elements arranged in a matrix, and at least a first filtering device (10) for processing the signals issuing from said sensitive elements. The filtering device (10) includes a plurality of linear filters (Fmd1, Fmd2, Fdg1, . . . Fdg6) corresponding to medians and diagonals with respect to the sensor for supplying a plurality of filtering indications. An elimination device (14) eliminates the extreme results of these indications and an estimation device (16) supplyies a valid indication from the non-eliminated indications. Thus, the faulty sensitive elements of the sensor (3) do not degrade the images excessively.

Abstract: This camera having a contour improvement circuit (13) is formed from 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. It is in the form of a first branch (B1) in which said first filtering device (10) is inserted, and at least a second branch (B2) in which the contour improvement circuit (13) is inserted in order to act on the high frequencies taking account of all the signals issuing from said elements, and a combination device (16) for supplying an image from the output signals of said branches.

Abstract: This camera is in the form of a sensor (3) composed of light-sensitive elements arranged in a matrix, and at least a first filtering device (10) for processing the signals issuing from said sensitive elements. The filtering device (10) includes a plurality of linear filters (Fmd1, Fmd2, Fdg1, . . . Fdg6) corresponding to medians and diagonals considered on the sensor for supplying a plurality of filtering indications. An elimination device (14) for eliminating the extreme results of these indications and an estimation device (16) for supplying a valid indication from the non-eliminated indications. Thus, the faulty sensitive elements of the sensor (3) do not too much degrade the images issued from this apparatus.

Abstract: This digital camera comprises a lens system (5) for focusing the image of a subject (10) on a sensitive plate (7), a control system formed, inter alia, by a motor (8) that act on the lens system to ensure a sharp image of the subject on the sensitive plate.
