I have tried to implement JavaCameraView in android but I am facing one issue like I am not able to show camera in full screen. It is showing in 480(width)x720(height) by default. How can show preview in full screen like system Camera App.

This is python code. But you will have to convert to java.

import cv2
filename = 'opencv.jpg'
W = 1200
oriimg = cv2.imread(filename)
height, width, depth = oriimg.shape
print(height,width,depth)
imgScale = W / width
newX, newY = oriimg.shape[1] * imgScale, oriimg.shape[0] * imgScale
newimg = cv2.resize(oriimg, (int(newX), int(newY)))
cv2.imshow("Show by CV2", newimg)
cv2.waitKey(0)
