Rendering control method, rendering control device and mobile terminal

The invention discloses a rendering control method, a rendering control device and a mobile terminal. The method comprises the following steps of promoting a refresh rate value of a front camera to a preset target refresh rate value from a default refresh rate value when the mobile terminal opens a virtual reliability application; figuring out a fine rendering region according to the target refresh rate value obtained after promotion and the current point of regard of a user on a screen of the mobile terminal in order to carry out fine rendering on pixel points in the fine rendering region; carrying out normal rendering processing on other regions outside the fine rendering region; and lastly, presenting a rendered picture to the user on the screen. The invention has the following beneficial effects that the precise rendering region is determined by the target refresh rate value which can be better adaptive to the rapid eye movement than the existing fixed refresh rate value, the obtained precise rendering region can better cover the visual range of the user, the user is prevented from perceiving a rough rendering picture outside the fine rendering region during the rapid eye movement, and the visual perception and the satisfaction of the user are improved.
