ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an image transforming device and more particularly to an improvement of the device for transforming an original picture image to such as a drawing type image and a painting type image.
2. Description of the Related Art
Almost all structural characteristics contained in an image can be grasped as a linear characteristic of the edge part of contour and boundary of the object contained. And the drawings expressed by grasping the image as the linear characteristic can give a strong impression on the viewer as well as giving psychological effects on him. Accordingly, linearization of the image has been used as a method to show special effects in the video field.
Furthermore, even though pictures such as crayon drawings and oil paintings are just colored linear pictures, they have artistic beauties and special flavors of their own.
Heretofore, these linear drawings and paintings have been made by the man's handwork and regarded unsuitable to be made with the aid of the mechanical means such as computer.
Moreover, in general, an animated cartoon consists of a number of lines and pictures drawn with the lapse of time and made by many peoples' handworks.
However, it requires much labor and time for making the linear drawing and painting by means of the human handwork, and the method to realize these works easily has been desired. Then our company has been proposed an image data processing device which is shown in U.S. Pat. No. 5,101,440.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an image transforming device which is capable of transforming the original image to linear drawings and paintings in real time and adjusting more detailed than the apparatus shown in U.S. Pat. No. 5,101,440.
The foregoing objects and other objects of the invention have been achieved by the provision of an image transforming device in which an edge signal of inputted image detected by the edge detecting means is normalized by normalization means and two signals will be mixed making the nonlinear transformed edge signal as the key signal in order to decrease intermediate tone elements. Since these processings can be realized by simple processing such as multiplication and addition, drawing type images extracted only the edges having large light and shade contrast in the inputted images can be obtained real time.
The nature, principle and utility of the invention will become more apparent from the following detailed description when read in conjunction with the accompanying in which like parts are designated by like reference numerals or characters.
