1. A control method for an imaging system, wherein the imaging system includes a display device and a dimming lens disposed on a display side of the display device, the dimming lens is capable of moving toward or away from the display device to adjust an object distance from the display device to the dimming lens;
the method comprises:
determining the object distance when the dimming lens moves to a set position;
according to the object distance, determining an image distance from a virtual image, generated by a display image of the display device through the dimming lens, to the dimming lens; and
according to the determined image distance and a correlation between the image distance and a resolution of the display image, determining a resolution corresponding to the determined image distance; and
controlling the display device to display the display image at the determined resolution;
wherein according to the determined image distance and the correlation between the image distance and the resolution of the display image, determining the resolution corresponding to the determined image distance, includes:
if the determined image distance is within a first image distance range, determining that the resolution corresponding to the determined image distance is equal to a screen resolution of the display device; and
if the determined image distance is within a second image distance range, determining that the resolution corresponding to the determined image distance is smaller than the screen resolution of the display device;
wherein each image distance value in the second image distance range is greater than each image distance value in the first image distance range;
wherein the second image distance range includes a third image distance range and a fourth image distance range; according to the determined image distance and the correlation between the image distance and the resolution of the display image, determining the resolution corresponding to the determined image distance, further includes:
if the determined image distance is within the third image distance range, determining that the resolution corresponding to the determined image distance is a first resolution; and
if the determined image distance is within the fourth image distance range, determining that the resolution corresponding to the determined image distance is a second resolution;
wherein each image distance value in the fourth image distance range is greater than each image distance value in the third image distance range; the first resolution is smaller than the screen resolution of the display device and larger than the second resolution; a number of horizontal pixels of the second resolution is 0.5 times a number of horizontal pixels of the screen resolution of the display device, and a number of vertical pixels of the second resolution is 0.5 times a number of vertical pixels of the screen resolution of the display device.
