A non-transitory readable recording medium storing a program for causing a processor to execute a control method of an image processing device including the processor and a communication device, in which the program causes the processor to execute a control process of the image processing device, the control process comprising:
- acquiring a first video obtained by imaging outside scenery of a first vehicle by using the communication device;
- when detection is made that a second vehicle appears on the first video, implementing image processing that degrades visibility of a video with respect to a first image area encompassing an entirety of the second vehicle appearing on the first video until an entirety of a specific part of the second vehicle appears on the first video;
- and
- when detection is made that the entirety of the specific part of the second vehicle appears on the first video, ending the image processing with respect to the first image area and implementing image processing that degrades visibility of a video with respect to a second image area corresponding to the specific part of the second vehicle on the first video.
