An image evaluation method, including: obtaining a test image including a first lattice pattern formed by image edges; aligning the test image using the image edges to generate an aligned image including a second lattice pattern formed by aligned image edges; generating a compressed image by compressing the aligned image; and generating a quantified result by quantifying a per-pixel difference between the compressed image and the aligned image.

Image evaluation method that can quantify images distorted by artifacts, computer program performing the method, and computing device

An apparatus controls a backlight of a display panel of a camera system. 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.
