Abstract
The present invention provides a control system for and method of controlling an apparatus of the type for exposing photographic film with image data which control system and method are adapted to compensate for variations in the exposure intensity, while also adjusting for different formats of image data. In one form, control system of the present invention determines the format of the image data, determines an exposure format in response to the format of the image data for producing an image on the film having a predetermined size, and calibrates an intensity for the exposure in response to the determined exposure format.
Claims17
A system for controlling an apparatus of the type for exposing photographic film with image data in any one of a plurality of different imaging formats, each of said formats being defined by a unique pixel array comprising a predetermined number of lines and a predetermined number of pixels per line which serve to reconstruct an image represented by said image data, said system comprising:
- means for determining the imaging format of a particular set of image data, including the number of lines and the number of pixels per line of said format;
- means for determining an exposure format defining the manner in which the film is exposed in response to the determined imaging format for the image data so as to produce an image of predetermined size on the film;
- and
- means, responsive to the determined exposure format, for calibrating the exposure intensity created by the apparatus when exposing the film in accordance with the determined exposure format.
A control system for controlling an apparatus of the type for exposing photographic film to an image represented by image data and having any one of a variable number of possible lines and a variable number of pixels per line of image data, said control system comprising:
- means for determining the number of lines and the number of pixels in each line of the image data representing said image;
- and
- control means, responsive to the determined number of lines and number of pixels in each line of the image data for controlling the number of exposure lines and the spacing thereof when exposing the film with said apparatus.
A method of controlling an apparatus of the type for exposing photographic film with image data having any one of a plurality of possible image formats each defined by a predetermined number of lines and a predetermined number of pixels per line of image data, said method comprising the steps of:
- determining the image format, including the number of lines and the number of pixels per line, of a set of image data;
- determining the exposure format in response to the image format of the image data for producing an image of a predetermined size on the film;
- and
- calibrating the exposure intensity provided by the apparatus in response to the determined exposure format.
A control system for use in controlling an apparatus of the type for exposing photographic film to an image in any one of a plurality of pixel array formats and represented as a set of image data, said control system comprising:
- means for sending said image data and for determining the pixel array format of the image represented by said image data;
- and
- control means, responsive to the determined pixel array format, for controlling the height and width of each pixel of said array when exposing the film with said apparatus so as to produce an image on said film.
