Abstract: An embodiment of an image enhancement method is introduced for use in an electronic device. An image composed of a plurality of pixel values is first received, and each pixel therein is separated into two channels. The image is further divided into a plurality of blocks. A distribution of a selected channel is determined for each block, which is selected from the two channels. For each pixel, the pixel value of the selected channel is adjusted according to at least one distribution corresponding to at least one neighboring block. For each pixel, the pixel value of the other channel is adjusted according to the adjusted pixel value of the selected channel. As a result, the adjusted image is provided.

Abstract: An exposure value adjustment apparatus, method, and non-transitory tangible machine-readable medium thereof are provided. The exposure value adjustment apparatus includes a camera module and a processor. The camera module captures a reference image by a base exposure value. The processor generates a histogram of the reference image, divides the histogram into a low partial histogram, a middle partial histogram, and a high partial histogram by a first threshold and a second threshold, decides a high exposure value according to the low partial histogram and the middle partial histogram, decides a low exposure value according to the high partial histogram and the middle partial histogram, and decides a middle exposure value according to the high exposure value and the low exposure value. The low exposure value is lower than the high exposure value, and the middle exposure value is between the high exposure value and the low exposure value.

Abstract: A color sampling method includes detecting a touch input on a touch screen, determining a first region corresponding to the touch input, performing a temporal analysis on the first region of a plurality of image frames to determine representative color values of pixels within the first region, determining a second region within the first region, and performing a spatial analysis on the second region to determine candidate color value corresponding to the touch input according to the representative color values of pixels within the second region.

Abstract: Methods and systems for scene recognition are provided. At least one dark region from an image is searched, and color for pixels of the at least one dark region is calculated. It is determined whether a proportion of low colorfulness pixels to the pixels of the at least one dark region is greater than a predefined threshold, wherein when the color information of the respective pixel is less than a specific level, the respective pixel is determined as low colorfulness. When the proportion of low colorfulness pixels to the pixels of the at least one dark region is greater than the predefined threshold, a scene corresponding to the image is not determined as a backlight scene.
