Display control device

A display control device comprising:

• at least one of (i) a circuit and (ii) a processor having a memory storing computer program code, wherein the at least one of the circuit and the processor having the memory is configured to cause the display control device to execute a calculation acceleration acquisition processing and a display processing, wherein
• the calculation acceleration acquisition processing includes a process of acquiring a calculation acceleration variable,
• the calculation acceleration variable includes a variable indicating a calculated acceleration of a vehicle in response to a driving state of the vehicle, or a driving state of the vehicle that generates an acceleration of the vehicle,
• the display processing includes a process of displaying an image that is visible to an occupant of the vehicle by operating a display device, and includes an image variation process,
• the image variation process includes a process of changing the image in response to the calculation acceleration variable,
• the calculation acceleration variable includes a variable related to a steering angle of a steering wheel of the vehicle as a variable indicating a driving state of the vehicle that generates a lateral acceleration of the vehicle, and
• in a case where the steering angle deviates from zero, the image variation process includes a process of changing the image with respect to a straight traveling of the vehicle, and includes a process of changing an amount of change in the image in response to the steering angle, when a magnitude of the steering angle is greater than zero, such that the magnitude of the steering angle becomes larger when the amount of change in the image is larger than when the amount of change in the image is smaller,
• wherein the image variation process includes a steering filter process to lower a responsiveness of change in the image with respect to a change in the steering angle.
