Rasberry Pi camera simulation

Question

Good day, how can i simulate a rasberry pi camera. i want the camera to take a picture when a button is pressed and store the pictures in MySQL database

tried with the following code and displaying the picture on the tft screen but unfortunately after some time the simulation will timeout.

# !/usr/bin/env python3

# Modules
from goto import with_goto
from stddef import *
import var
import pio
import resource
from datetime import datetime

# Peripheral Configuration Code (Do Not Edit)
#---CONFIG_BEGIN---
import cpu
import FileStore
import VFP

def peripheral_setup () :

 pio.storage=FileStore.FileStore ()
 pio.server=VFP.VfpServer ()
 pio.BTN1=Generic.Button (pio.GPIO19)
 pio.CAM1=camera.RPiCamera ()
 pio.LCD1=Displays.TFTDisplay (pio.GPIO25, pio.GPIO24)
 pio.storage.begin ()
 pio.server.begin (0)
# Install interrupt handlers

def peripheral_loop () :
 pio.server.poll ()

#---CONFIG_END---
def variables_setup () :
# Flowchart Variables
 var.image = ''

# Flowchart Routines
@with_goto
def chart_SETUP () :
 pio.LCD1.loadImage ("picturestart.png", 0)
 return

@with_goto
def chart_LOOP () :
 while not (pio.BTN1()) :
  pass

 pio.CAM1.capture (25)
 var.image = pio.CAM1.getLastImage ()
 pio.LCD1.loadImage (var.image, 0)
 return

# Main function
