This article introduces the knowledge of "what is the method of matlab using notebook camera". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Built-in camera

This is an example of GUI, with the fig file linked at the end of the text.

Function varargout = camera (varargin)

Gui_Singleton = 1

Gui_State = struct ('gui_Name', mfilename,...

'gui_Singleton', gui_Singleton,...

'gui_OpeningFcn', @ camera_OpeningFcn,...

'gui_OutputFcn', @ camera_OutputFcn,...

'gui_LayoutFcn', [],...

'gui_Callback', [])

If nargin & & ischar (varargin {1})

Gui_State.gui_Callback = str2func (varargin {1})

End

If nargout

[varargout {1:nargout}] = gui_mainfcn (gui_State, varargin {:})

Else

Gui_mainfcn (gui_State, varargin {:})

End

Function camera_OpeningFcn (hObject, eventdata, handles, varargin)

Handles.output = hObject

Guidata (hObject, handles)

Function varargout = camera_OutputFcn (hObject, eventdata, handles)

Varargout {1} = handles.output

Function pushbutton1_Callback (hObject, eventdata, handles)

Axes (handles.axes1)

Vid1=videoinput ('winvideo',1,'YUY2_640x480')

VidRes1=get (vid1,'VideoResolution')

NBands1=get (vid1,'NumberOfBands')

Set (vid1,'ReturnedColorSpace','rgb')

Himage1=imshow (zeros (vidRes1 (2), vidRes1 (1), nBands1))

Preview (vid1,himage1)
