Problems solved by technology

[0004] However, a disadvantage of known electronic still cameras is that the digital filtering means only contain limited functionality
Another disadvantage of known electronic still cameras is that digital filtering means can only be applied after the digital image has been recorded
The drawbacks of this object-specific approach to digital filtering usually relate to the quality and creativity of the digital filtering device's effects, respectively.

Embodiment Construction

[0018] It should be understood that the following description is only for the purpose of illustrating a particular embodiment of the invention shown in the drawings, and does not define or limit the invention, which is defined or limited in the appended claims.

[0019] attached figure 1 is a functional block diagram showing the overall and electronic schematic structure of the electronic still camera 10 in the present embodiment of the present invention. A CPU 50 is provided for controlling the entire electronic still camera 10, especially image sensing and processing.

[0020] An optical image is obtained by an optical system including a lens 11, an iris stop 12 and other elements formed on the photosensitive surface of an image pickup element 13, which is a CCD in this example. The lens 11 and the iris diaphragm 12 are driven by a focusing and iris diaphragm drive circuit 17, respectively. The image pickup element 13 photoelectrically converts the optical image formed on ...

Abstract

In an electronic camera (10) carrying means (72) for carrying digital filter means are constructed to enable an updating and / or expanding of the digital filter means in order to enable and provide a high-quality digital effect filter for photographing. Preferably, take-up means (70) are provided for taking up the carrying means (72) which are realized as a plug-in card (72).

Description

technical field [0001] The invention relates to an electronic camera including a digital filter. Background technique [0002] One such electronic camera is disclosed in Japanese Patent Application Laid-Open No. 04-081176, wherein the electronic camera is configured as a so-called electronic still camera. The electronic still camera is capable of correcting a generated digital image by means of a digital filter. This digital filter calculates what would be achieved in conventional chemical photography if the aperture was fully opened if only the in-focus subject were in focus. The rest of the image will be very blurry, so that in-focus objects are highlighted. [0003] The known electronic still camera provides a recording system for recording digital images on a recording medium, and a reproducing system for outputting an image to an existing digital image in the case of correcting the data image using the above-mentioned digital filter means. Display devices of known el...
