There is provided a program creation apparatus with improved operability in checking an operation of a created control program, including: a program generating section for acquiring a camera image from a camera based upon an image pick-up trigger signal, to extract a measurement result from the acquired camera image as a control program for the image processing controller; a simulation part for executing the control program; and a communication section for transferring the control program to the image processing controller, wherein the simulation part includes an offline simulation section for extracting a measurement result from a camera image previously held as a registration image, and an online simulation section for acquiring a camera image from the camera through the image processing controller when executing the control program, to extract the measurement result from the acquired camera image.
