Need help with Camera Configuration

[gitty889]

I am trying to save my images in 12bits but it saves in 8bit. Here's my code, please can you suggest what i am doing wrong?

from pypylon import pylon
import cv2
import numpy as np
import os
from datetime import datetime

camera = None

def initialize_camera():
    global camera
    camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice())
    camera.Open()
    # Set the pixel format to Mono 12
    camera.PixelFormat.Value = "Mono12"
    # Set the sensor bit depth mode to Manual
    camera.BslSensorBitDepthMode.Value = "Manual"
    # Set the sensor bit depth to 12 bit
    camera.BslSensorBitDepth.Value = "Bpp12"

I have the basler a2A1920-51gmPRO Operating System- Windows

Is the code, where you save the images missing?

Here is the function to capture and save image

def capture_and_save_image(base_folder):
    global camera
    date_folder = datetime.now().strftime("%Y-%m-%d")
    folder_path = os.path.join(base_folder, date_folder)
    os.makedirs(folder_path, exist_ok=True)
    file_path = os.path.join(folder_path, datetime.now().strftime("%Y%m%d_%H%M%S.bmp"))

    grab_result = camera.RetrieveResult(5000, pylon.TimeoutHandling_ThrowException)
    if grab_result.GrabSucceeded():
        image = grab_result.Array
        cv2.imwrite(file_path, image)
    grab_result.Release()
    return file_path

I would use PNG to store 16bit images. Can you output

print(image.shape)

Before writing?
