Abstract

Provided herein is an AV processing apparatus which displays a plurality of video signal designating areas which are used to designate an output of each video signal on a touch panel in accordance to a plurality of input video signals, performs a mixing process based on a touch position on the touch panel, and performs a switching process of video signals based on a movement of the touch position.

Claims

1-9. -9. (canceled)

10. An AV processing apparatus comprising:

an input unit that is used to receive a plurality of AV signals as a audio signal or a video signal;

an operating unit that includes a touch panel having a display function and is used for an edit operation of a plurality of AV signals with the touch panel having the display function;

a display control unit that controls to display on the touch panel having the display function;

an output AV signal generating unit that performs edit processes including a mixing process and a switching process on a plurality of AV signals based on the edit operation by the operating unit, and generates an output AV signal as an output object; and

an output unit that outputs the output AV signal generated by the output AV signal generating unit,

wherein the display control unit displays a plurality of AV signal designating areas which is used to designate an output of each AV signal on the touch panel having the display function corresponding to a plurality of AV signals input from the input unit, and the output AV signal generating unit performs the mixing process of a plurality of AV signals based on a touch position on the touch panel having the display function and performs the switching process of a plurality of AV signals based on a movement of the touch position.

11. The AV processing apparatus according to claim 10, wherein the display control unit determines arrangements of a plurality of AV signal designating areas based on the number of the AV signals input from the input unit.

12. The AV processing apparatus according to claim 11, wherein the display control unit displays a plurality of AV signal designating areas by arranging at a position corresponding to each apex of a polygon according to the number of the AV signals.

13. The AV processing apparatus according to claim 10, wherein the display control unit displays a video of a video signal on a corresponding AV signal designating area when the AV signal is the video signal.

14. The AV processing apparatus according to claim 10, wherein each AV signal designating area has a reference point as reference that is used to determine the mixing rate in the mixing process and the switching rate in the switching process, and the output AV signal generating unit determines the mixing rate or the switching rate of each AV signal corresponding to each AV signal designating area based on a distance between the touch position and each reference point provided in each AV signal designating area with respect to the touch position or the movement of the touch position.

15. The AV processing apparatus according to claim 10, wherein the output AV signal generating unit sets the output of the AV signal corresponding to the AV signal designating area at 100% with respect to the touch position or the movement of the touch position inside the AV signal designating area, and determines the mixing rate or the switching rate of each AV signal corresponding to each AV signal determining area based on a minimum distance from the touch position to each AV signal designating area with respect to the touch position or the movement of the touch position outside the AV signal designating area.

16. The AV processing apparatus according to claim 10, wherein each AV signal designating area has a reference point as reference that is used to determine the mixing rate in the mixing process and the switching rate in the switching process,

wherein an operation mode setting unit is provided that sets either a first operation mode or a second operation mode;

the first operation mode determining the mixing rate or the switching rate of each AV signal corresponding to each AV signal designating area based on a distance between the touch position and each reference point provided in each AV signal designating area with respect to the touch position or the movement of the touch position; and

the second operation mode setting the output of the AV signal corresponding to the AV signal designating area at 100% with respect to the touch position or the movement of the touch position inside the AV signal designating area and determining the mixing rate or the switching rate of each AV signal corresponding to each AV signal designating area based on the minimum distance from the touch position to each AV signal designating area with respect to the touch position or the movement of the touch position outside the AV signal designating area;

and wherein the output AV signal generating unit performs the mixing process or the switching process based on a setting by the operation mode setting unit.

17. The AV processing apparatus according to claim 10 further comprising an arrangement change instructing unit that is used to instruct an arrangement change of each AV signal designating area on the touch panel having the display function, wherein the display control unit changes an arrangement of one or more AV signal designating areas corresponding to one or more AV signals included in the output AV signal at around a center with respect to other AV signal designating areas based on an instruction by the arrangement change instructing unit.

18. The AV processing apparatus according to claim 10, wherein the edit process includes an effect process that applies an effect on the output AV signal, the display control unit displays one or more effect designating areas provided per effect on the touch panel having the display function, and the output AV signal generating unit performs the effect process on the output AV signal based on the touch position or the movement of the touch position on the touch panel having the display function.

19. A program causing a computer to function as each unit of the AV processing apparatus according to claim 10.
