Image simulation method, image computer and target simulator

The invention provides an image simulation method, an image computer and a target simulator. The method specifically comprises the steps that an image computer receives simulation data required by image rendering and an image rendering signal from the target simulator; the image computer converts the simulation data into digital image data under the control of the image rendering signal; the imagecomputer transmits the digital image data to a target simulator. According to the invention, the image computer and the target simulator are enabled to carry out digital image calculation and opticalimage output by taking the frequency of the synchronous exposure signal as a reference; meanwhile, the image computer and the target simulator are transmitted at the frequency which is several timesof the frequency of the synchronous exposure signal, so the time delay of the image simulation system is shortened. 本发明提供一种图像仿真方法、图像计算机以及目标模拟器，其方法具体包括：图像计算机接收图像渲染所需的仿真数据，以及来自目标模拟器的图像渲染信号；所述图像计算机在所述图像渲染信号控制下将所述仿真数据转化为数字图像数据；所述图像
