Abstract:
1. A stereoscopic display device, comprising: a stereoscopic display panel including a display panel section having a plurality of unit pixels and an image distributing section for distributing and outputting visual recognition image data sent out from the display panel section as visual recognition stereoscopic image information towards outside; a display panel driving section which drives the display panel section of the stereoscopic display panel; and a stereoscopic image generating module which controls actions of the display panel driving section and generates 3D image data for driving the display panel based on three-dimensional data containing depth information specified in advance, wherein the stereoscopic image generating module is provided with: a temperature sensor which detects temperatures of the image distributing section; and a data storage section which stores information regarding an effective linear expansion coefficient difference between the image distributing section and the display panel section when the both are in a fixed state, size of the display panel section, resolution of the unit pixels, and a reference temperature as parameter information regarding an inherent stereoscopic viewing region of the stereoscopic display panel, and the stereoscopic image generating module comprises: a deformation amount calculating section which calculates a temperature difference ΔT between temperature information detected by the temperature sensor and the reference temperature, and calculates a deformation amount that is a contraction amount or an expansion amount which changes due to a change in surrounding environment temperatures of the image distributing section based on the temperature difference ΔT and the information stored in the data storage section; and a main arithmetic operation controller which, when the deformation amount regarding contraction or expansion is calculated by the deformation amount calculating section, generates 3D image data corresponding thereto and outputs the generated data to the display panel driving section for driving the display panel wherein the stereoscopic image generating module comprises: a camera setting information storage section which stores a pre-specified setting position parameter regarding a camera setting of rendering processing that is executed for acquiring the 3D image data from the three-dimensional data as a first camera setting A; and a temperature difference judging section which performs an arithmetic operation regarding whether or not an absolute value of the temperature difference ΔT between the detected temperature and the reference temperature is equal to or less than an absolute value of a reference value ΔTth set in advance, and judges whether or not it is under a temperature environment that requires correction of a parallax amount specified on an x-axis on an xy plane as a screen face from the three-dimensional data containing depth information, and the main arithmetic operation controller comprises a 3D image data generating function which operates when it is judged by the temperature difference judging section that temperature difference ΔT is |ΔT|≦|ΔTth| and it is under a temperature environment that does not require correction of the parallax amount to perform rendering processing on the three-dimensional data under a condition of the first camera setting A, and to generate and output two-dimensional 3D image data having the parallax amount and the depth information of the three-dimensional data for driving the display panel.
