Embodiment Construction

[0048] Various example embodiments will now be described more fully with reference to the accompanying drawings, in which some example embodiments are shown.

[0049] figure 2 A flowchart showing a method for calibrating an IID according to an embodiment of the present invention.

[0050] Such as figure 2 As shown, in step 201, the image displayed on the IID (hereinafter referred to as "IID display image") is captured by the image capturing device at M (M is a natural number greater than 1) different shooting orientations, so as to obtain multiple images (hereinafter referred to as "captured images"). At this time, the IID display image is displayed on the captured image captured.

[0051] The image capture device may be implemented using an image sensor such as a Charge Coupled Device (CCD) sensor, a Complementary Metal Oxide Semiconductor (CMOS) sensor, or the like. The shooting orientation indicates a shooting position and / or shooting posture.

Abstract

A calibration method and device for an integrated imaging display are provided, the method comprising: photographing an IID display image displayed on an IID in a plurality of different shooting orientations by an image capturing device to obtain a plurality of photographed images; according to the IID display Image and each captured image obtained, determine the vertical distance between the image capture device and the LCD panel of the IID at each shooting orientation; determine the lens image spacing at each shooting orientation; determine according to the determined vertical distance and lens image spacing Lens pitch and lens gap, where the lens pitch represents the lateral distance between the optical centers of two adjacent microlenses in the microlens array MLA in the IID, and the lens gap represents the distance from the optical center of the microlens to the LCD panel.

Description

technical field [0001] The present invention relates to integrated imaging displays (IIDs). More specifically, it relates to an IID calibration method and equipment. Background technique [0002] Integrated imaging is a 3D display technology with continuous motion parallax that can display 3D images under daylight illumination without wearing glasses. figure 1 A schematic diagram showing the structure of an integrated imaging display (IID). The IID works by displaying an Elemental Image Array (EIA), ie, an image, on a Liquid Crystal Display (LCD) panel behind a Microlens Array (MLA), so that a user can view a 3D effect. [0003] In practice, the actual hardware characteristics of IIDs may differ from their original design due to possible errors in the manufacturing and installation process. These differences often lead to system errors that degrade display performance. Therefore, an IID calibration technique is needed to detect these errors. Contents of the invention ...
