Embodiment Construction

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050]In this specification, the optical fiber scanning imaging system is first described. The optical fiber scanning imaging system uses the actuator in the optical fiber scanner to drive the high-speed vibration of the optical fiber, and cooperates with the laser modulation algorithm to realize the display of image information. like Figure 1A As shown, it is an existing fiber scanning imaging system, which mainly includes: a proc...

Abstract

The invention discloses a color correction method and an optical fiber scanning imaging system, the optical fiber scanning imaging system comprises a plurality of display units, each display unit comprises a plurality of color channels, the color information output by each color channel of each display unit is acquired, and the color information output by each color channel of each display unit is acquired; the method comprises the following steps: acquiring color information of each display unit, generating a mapping relation between an illumination value and a gray scale according to the acquired color information, and then correcting a target illumination value needing to be output for each color channel of each display unit to ensure the color consistency of the system; therefore, the problem of color unevenness caused by laser response difference in the existing internal modulation display system technology is solved.

Description

technical field [0001] The invention relates to the field of projection display, in particular to a color correction method and an optical fiber scanning imaging system. Background technique [0002] The optical fiber scanning imaging system generally includes an optical fiber scanner and a light source. The light source generates the light of each pixel point on the image, and then couples the light of each pixel point into the optical fiber, and then the optical fiber scanner drives the optical fiber to scan and vibrate, so as to scan and vibrate the fiber. The light of each pixel on the image is projected onto the projection screen one by one to form a projection screen. [0003] In order to realize large-screen display based on optical fiber scanning, multiple optical fiber scanning projection sub-units can be used for splicing. Therefore, it is necessary to collect and correct the color of each projection sub-unit to achieve uniform and consistent colors in each area o...
