The disclosure provides an image processing apparatus, an image processing system, and recording medium capable of achieving both reduction of the amount of data and securement of reproducibility. An image processing apparatus generates compressed image data by compressing raw image data acquired by imaging an object into a JPEG format, restores the compressed image data to restored image data of a bmp format, and then acquires a first result by executing an image measurement processing on the restored image data. The image processing apparatus stores the compressed image data and the first result in association with each other.
