摘要： A method of increasing the dynamic range of an image comprising a plurality of pixels each having a luminance value within a first luminance dynamic range. The method includes determining a background luminance value for each pixel of the image and determining a minimum and a maximum of the background luminance values. A conversion factor is then determined for each pixel of the image based on the minimum and maximum of the background luminance values. The image id converted from the first luminance dynamic range to a second luminance dynamic range by multiplying the luminance value of each pixel of the image by its conversion factor.

摘要： A method of reducing power consumption in a liquid crystal display illuminated by a backlight device includes dimming the backlight and adjusting the intensity of the image to compensate for the dimmed backlight. A dimming factor for the backlight is based on a clipping point determining from the pixel intensity distribution of the image signal. The intensity of the image is adjusted based on the dimming factor, wherein a first tone mapping function is used to adjust pixel intensities below an intensity threshold and a second tone mapping function is used to adjust pixel intensities above the intensity threshold.

摘要： A method of converting an image signal from an original dynamic range to a target dynamic range includes dividing the original dynamic range and the target dynamic range in to a plurality of corresponding sub-ranges and mapping each original sub-range to its corresponding target sub-range. One of the dynamic ranges is divided into a plurality of sub-ranges having equal size and the other dynamic range is divided into the corresponding sub-ranges each having a size based on a characteristic of the corresponding equal size sub-ranges. The invention may be employed in display, capture and image processing apparatus.
