The apparatus includes a sub-pixel extracting unit, an ambient light luminance calculating unit, and a backlight controller. The sub-pixel extracting unit extracts sub-pixel luminance values from image data, where the image data is indicative of a current image frame defined by a plurality of pixels, and where each of the pixels includes a plurality of sub-pixels. The ambient light luminance calculating unit calculates an ambient light luminance value of the current image frame from the sub-pixel luminance values extracted by the sub-pixel extracting unit. The backlight controller which generates a backlight control signal based on a comparison between the calculated ambient light luminance value of the current image frame and an ambient light luminance value of a previous image frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for and method of controlling backlight of display panel in camera system","description":"An apparatus controls a backlight of a display panel of a camera system.
