Interior mirror assembly with display

摘要

An interior rearview mirror system and assembly includes a variable reflectivity reflective element and a video display screen disposed behind the reflective element and operable to display images viewable through the reflective element by a person viewing the interior rearview mirror assembly when it is normally mounted in a vehicle. The video display screen may be operable to brighten or enhance the intensity of images displayed by the video display screen responsive to a dimming condition of the variable reflectivity reflective element. The mirror system may include an image sensor and a decoder that decodes an output signal of the image sensor. The decoder has a microprocessor operable to control the video display screen, such that the captured image data are processed and images are displayed via operation of a common microprocessor. A compass chip may connect to a vehicle wire harness that extends from a vehicle headliner.

主权项

1. An interior rearview mirror system for a vehicle comprising:
an interior rearview mirror assembly comprising a casing, a variable reflectivity reflective element, and a video display screen disposed in said casing and behind said reflective element, said video display screen operable to display images that are viewable through said reflective element by a person viewing said interior rearview mirror assembly when it is normally mounted in a vehicle equipped with said interior rearview mirror system; wherein said variable reflectivity reflective element comprises an electrochromic reflective element; wherein said interior rearview mirror assembly includes (i) a glare light sensor for sensing glare light at or near said reflective element and (ii) an ambient light sensor for sensing ambient light at said interior rearview mirror assembly; an image sensor operable to capture images of a scene encompassed by a field of view of said image sensor; wherein said interior rearview mirror assembly comprises a decoder that decodes analog output signals of said image sensor, said decoder having a microprocessor operable to (i) process image data and (ii) control said video display screen via a digital signal and (iii) control dimming of said electrochromic reflective element; wherein said decoder is responsive to a glare light output of said glare light sensor and an ambient light output of said ambient light sensor; wherein said microprocessor of said decoder comprises on screen display capability; wherein said decoder comprises at least one of on screen display circuitry, image enhancement circuitry, a 2D de-interlacing engine and a high quality scalar; wherein said decoder is operable to provide at least one of (a) programmable hue of a display displayed by said video display screen, (b) programmable brightness of a display displayed by said video display screen, (c) programmable saturation of a display displayed by said video display screen, (d) programmable contrast of a display displayed by said video display screen, (e) programmable sharpness control of a display displayed by said video display screen, (f) programmable sharpness control of a display displayed by said video display screen with vertical peaking, (g) programmable color transient improvement control of a display displayed by said video display screen, (h) programmable panorama/water-glass scaling of a display displayed by said video display screen, (i) programmable Gamma correction tables for said video display screen, (j) programmable black/white stretch of a display displayed by said video display screen and (k) programmable favorite color enhancement of a display displayed by said video display screen; wherein, responsive to said outputs of said glare light sensor and said ambient light sensor, said microprocessor of said decoder (i) adjusts the intensity of images displayed by said video display screen and (ii) controls dimming of said electrochromic reflective element, and wherein said microprocessor of said decoder also provides on screen display comprising graphic overlays.
