A projection light color adjusting method and a projection light color adjusting device

Abstract

The invention provides a projection light color adjusting method and a projection light color adjusting device, and relates to the technical field of vehicle-mounted projection. The method comprises the steps of obtaining gray values of an original image and a projection image corresponding to the original image; calculating to obtain a gray difference value according to the gray values of the original image and the projection image; according to a preset rule and the gray difference value, calculating to obtain a gray deviation value; and adjusting the projection light intensity according tothe gray scale deviation value, and obtaining the adjusted projection light intensity. According to the method, the gray scale deviation value is used for adjusting the projection light intensity, theadjusted projection light intensity is obtained, projection is carried out again, a clear projection image with the uniform light color is obtained, meanwhile, the method is simple in calculation process and good in practicability, and the problem that the vehicle-mounted projection effect is poor is effectively solved.

Description

technical field

[0001] The present invention relates to the technical field of vehicle-mounted projection, in particular, to a projection light color adjustment method and a projection light color adjustment device. Background technique

[0002] Projector is a common audio-visual entertainment device in daily life. It has a wide range of applications. The projection screen is large and clear, and the entertainment experience is relatively good. The observer perceives the image information visually, and the reflected light of the projected image stimulates the visual nerve. The stimulus source is the inherent texture of the projected surface, the reflection of the projected surface to the projected beam, and the brightness of the projected environment. Because it is reflected light, the eyes are not easy to fatigue when the brightness is suitable, and the stimulation is relatively small (display).

[0003] Usually, the interior space of an ordinary car is small and mostly ha...
