Picture editing apparatus in a digital still video camera system
First Claim
1. A picture editing apparatus in a digital still video camera system, comprising:
- means for storing a plurality of digital signals in frames in a memory card;
means for processing said digital video signals read-out from said memory card;
image data address generator means for generating image data addresses of said memory card;
one frame address generator means for generating a first picture assignment address of said memory card for one picture per each frame;
multi-picture address generator means for generating second picture assignment addresses of a specified number of pictures recorded in said memory card; and
picture mixing address generator means for generating third picture assignment addresses for selected pictures by mutually mixing a plurality of said selected pictures.

Abstract
A picture editing apparatus of a digital still video camera system includes a digital still video camera and a reproduction device which selectively controls a picture assignment address in a memory card for mixing and displaying a multiple of one or more pictures. An address generator that mixes 2 or more pictures in the same ratio generates an address to enable display of the mixed pictures and to read-out data (digital video signal) representing pictures recorded in the memory card. Therefore, it is capable of mixing pictures corresponding to the picture number recorded in a memory card as a single frame picture and displaying the mixed picture, creating new video images.

12. A picture editing apparatus used in a still video camera for mixing a multiple of pictures during a reproduction mode, said picture editing apparatus comprising:
-
memory means for storing a plurality of digital video signals by frames, each of said plurality of digital video signals representing a picture; reproduction buffer memory means for receiving said plurality of digital video signals from said memory means; one frame address generation means for generating a first picture assignment address signal when only one of said plurality of digital video signals is to be written from said memory means to said reproduction buffer memory means; multiple picture address generation means for generating a second picture assignment address signal when a multiple of digital video signals are to be written from said memory means to said reproduction buffer memory means; picture mixing address generation means for generating a third picture assignment address signal when a number of said plurality of digital video signals are to be mixed by superimposition; image data address generation means for generating an image data address signal representing addresses, in pixels, of picture data to be written to said reproduction buffer memory means synchronization generation means; for synchronizing the mixing of said number of said plurality of digital video signals by generating a clock signal; and first multiplexing means for enabling transmission of one of said first, second and third picture assignment address signals. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of editing pictures in a digital still video camera having a memory means storing pictures by frames, said method comprising:
-
alternatively selecting to read out from the memory means to a frame of a reproduction buffer, only one picture, a plurality of pictures with each picture occupying a distinct region of the frame of the reproduction buffer, and a plurality of pictures mutually superimposed in the frame of the reproduction buffer; generating a picture address for reading out a picture stored in the memory means if selecting to read out said plurality of pictures mutually superimposed in the frame of the reproduction buffer; generating an image data address corresponding to image data of the picture being read out if selecting to read out said plurality of pictures mutually superimposed in the frame of the reproduction buffer; and writing the image data to the reproduction buffer. - View Dependent Claims (26)

25. A method of editing pictures in a digital still video camera having memory means storing pictures by frames, said method comprising:
-
alternatively selecting to read out from the memory means to a frame of a reproduction buffer, only one picture, a plurality of pictures with each picture occupying a distinct region of the frame of the reproduction buffer, and a plurality of pictures mutually superimposed in the frame of the reproduction buffer; counting a clock signal using a counter to generate a counted signal if selecting to read out said plurality of pictures mutually superimposed in the frame of the reproduction buffer; detecting a number of pictures in the memory means to be mixed; clearing the counter after read out of image data from the memory means is complete; driving a latching unit for each picture set to be mixed; controlling the output of each latching unit in dependence upon said counted signal; generating an image data address corresponding to image data of the picture being read out if selecting to read out said plurality of pictures mutually superimposed in the frame of the reproduction buffer; and writing the image data to the reproduction buffer. - View Dependent Claims (27)

28. A picture editing apparatus used in a still video camera for mixing a multiple of pictures during a reproduction mode, said picture editing apparatus comprising:
-
memory means for storing a plurality of digital video signals by frames, each of said plurality of digital video signals representing a picture; reproduction buffer memory means for receiving said plurality of digital video signals from said memory means; picture mixing address generation means for generating a picture assignment address signal indicating locations of said multiple of pictures stored in said memory means, when a number of said plurality of digital video signals are to be mixed by superimposition; image data address generation means for generating an image data address signal representing addresses, in pixels, of picture data to be written to said reproduction buffer memory means; and synchronization generation means for synchronizing the mixing of said number of said plurality of digital video signals by generating a clock signal. - View Dependent Claims (29, 30, 31)
