任何用于显示来自相机的实时图像的快速 Python GUI

I am trying to display live images from my 1394 camera. Currently my code is able to obtain images in a loop from the camera and I was looking for any quick GUI that will update dynamically (as a separate thread). I can do this in PyQt maybe using QThreads but is there any recommendation or faster way of doing this?? Here's my code

#循环从相机捕捉帧

for frame in range(1,500):

print 'frame:',frame

TIME.sleep(1) #capture frame every second

image_binary    = pycam.cam.RetrieveBuffer()

#convert to PIL Image

pilimg = PIL.Image.frombuffer("L",(cimg.GetCols(),cimg.GetRows()),image_binary,'raw', "RGBA", 0, 1)
    # At this point I want to send my image data to a GUI window and display it

谢谢.

这是 wxPython 代码...

import wx
from PIL import Image

SIZE = (640, 480)

def get_image():
    # Put your code here to return a PIL image from the camera.
    return Image.new('L', SIZE)

def pil_to_wx(image):
    width, height = image.size
    buffer = image.convert('RGB').tostring()
    bitmap = wx.BitmapFromBuffer(width, height, buffer)
    return bitmap

class Panel(wx.Panel):
    def __init__(self, parent):
        super(Panel, self).__init__(parent, -1)
        self.SetSize(SIZE)
        self.SetBackgroundStyle(wx.BG_STYLE_CUSTOM)
        self.Bind(wx.EVT_PAINT, self.on_paint)
        self.update()
    def update(self):
        self.Refresh()
        self.Update()
        wx.CallLater(15, self.update)
    def create_bitmap(self):
        image = get_image()
        bitmap = pil_to_wx(image)
        return bitmap
    def on_paint(self, event):
        bitmap = self.create_bitmap()
        dc = wx.AutoBufferedPaintDC(self)
        dc.DrawBitmap(bitmap, 0, 0)

class Frame(wx.Frame):
    def __init__(self):
        style = wx.DEFAULT_FRAME_STYLE & ~wx.RESIZE_BORDER & ~wx.MAXIMIZE_BOX
        super(Frame, self).__init__(None, -1, 'Camera Viewer', style=style)
        panel = Panel(self)
        self.Fit()

def main():
    app = wx.PySimpleApp()
    frame = Frame()
    frame.Center()
    frame.Show()
    app.MainLoop()

if __name__ == '__main__':
    main()
