Abstract
An apparatus for carrying out translucent-processing to still and moving pictures, includes (a) a judgment unit which judges whether a picture to be displayed is a still or moving picture, (b) a memory which stores first data about first and second pictures to be processed, and second data indicative of a ratio at which pixels of the first and second pictures are blended, (c) a still picture processor which blends color-relating values of the pixels in a portion at which the first and second pictures overlap each other, at the ratio, for producing third data relating to a translucent picture, and stores the thus produced third data in the memory, and (d) a moving picture processor which blends color-relating values of the pixels in a portion at which the first and second pictures overlap each other, at the ratio, for producing fourth data relating to a translucent picture.

3. An apparatus for carrying out translucent-processing to still and moving pictures, comprising:
-
(a) a judgment unit which judges whether a picture to be displayed is a still or moving picture, and transmits a judgment signal accordingly;
(b) a memory which stores first data about first and second pictures to be processed, and second data indicative of a ratio at which pixels of said first and second pictures are blended;
(c) a still picture processor which, when said judgment signal indicates that a picture to be processed is a still picture, blends color-relating values of said pixels in a portion at which said first and second pictures overlap each other, at said ratio, for producing third data relating to a translucent picture, and stores the thus produced third data in said memory; and
(d) a moving picture processor which, when said judgment signal indicates that a picture to be processed is a moving picture, blends color-relating values of said pixels in a portion at which said first and second pictures overlap each other, at said ratio, for producing fourth data relating to a translucent picture. - View Dependent Claims (4)

5. An apparatus for carrying out translucent-processing to still and moving pictures, comprising:
-
(a) a central processing unit which judges whether a picture to be displayed is a still or moving picture, and transmits a judgment signal accordingly;
(b) a memory which stores first data about first and second pictures to be processed, and second data indicative of a ratio at which pixels of said first and second pictures are blended;
(c) a video interface through which video data is input into said apparatus;
(d) a digital differential analysis circuit electrically connected between said central processing unit and said memory;
(e) a texture mapping circuit electrically connected between said central processing unit and said memory;
(f) a bit-block transferring circuit for transferring a bit block between said central processing unit and said memory;
(g) a display macro circuit which controls picture-displaying;
(h) a still picture processor which, when said judgment signal indicates that a picture to be processed is a still picture, blends color-relating values of said pixels in a portion at which said first and second pictures overlap each other, at said ratio, for producing third data relating to a translucent picture, and stores the thus produced third data in said memory, said still picture processor being equipped in said bit-block transferring circuit; and
(i) a moving picture processor which, when said judgment signal indicates that a picture to be processed is a moving picture, blends color-relating values of said pixels in a portion at which said first and second pictures overlap each other, at said ratio, for producing fourth data relating to a translucent picture, said moving picture processor being equipped in said display macro circuit. - View Dependent Claims (6, 7)

(a) a central processing unit which judges whether a picture to be displayed is a still or moving picture, and transmits a judgment signal accordingly;
(b) a memory which stores first data about first and second pictures to be processed, and second data indicative of a ratio at which pixels of said first and second pictures are blended;
(c) a video interface through which video data is input into said apparatus;
(d) a digital differential analysis circuit electrically connected between said central processing unit and said memory;
(e) a texture mapping circuit electrically connected between said central processing unit and said memory;
(f) a bit-block transferring circuit for transferring a bit block between said central processing unit and said memory;
(g) a display macro circuit which controls picture-displaying;
(h) a still picture processor which, when said judgment signal indicates that a picture to be processed is a still picture, blends color-relating values of said pixels in a portion at which said first and second pictures overlap each other, at said ratio, for producing third data relating to a translucent picture, and stores the thus produced third data in said memory, said still picture processor being equipped in said texture mapping circuit; and
(i) a moving picture processor which, when said judgment signal indicates that a picture to be processed is a moving picture, blends color-relating values of said pixels in a portion at which said first and second pictures overlap each other, at said ratio, for producing fourth data relating to a translucent picture, said moving picture processor being equipped in said display macro circuit. - View Dependent Claims (9)

12. A method of carrying out translucent-processing to still and moving pictures, comprising the steps of:
-
(a) judging whether a picture to be displayed is a still or moving picture;
(b) storing first data about first and second pictures to be processed, and second data indicative of a ratio at which pixels of said first and second pictures are blended, into a memory;
(c) when said picture to be processed is a still picture, blending color-relating values of said pixels in a portion at which said first and second pictures overlap each other, at said ratio, for producing third data relating to a translucent picture, and storing the thus produced third data in said memory; and
(d) when said judgment signal indicates that a picture to be processed is a moving picture, blending color-relating values of said pixels in a portion at which said first and second pictures overlap each other, at said ratio, for producing fourth data relating to a translucent picture.

14. A method of carrying out translucent-processing to still and moving pictures, comprising the steps of:
-
(a) receiving first data of a still picture, second data of a still picture, third data of a moving picture, fourth data of a moving picture, and α
-blending ratio α
, and storing them into a memory;
(b) reading said first and second data and said blending ratio α
out of said memory;
(c) carrying out α
-blending process to both said first and second data, and said third and fourth data independently of each other; and
(d) storing said first and second data into said memory.
