Abstract: A lens including a filter, an aperture stop, and a lens set sequentially arranged along a first direction is provided. The filter includes a central region and a peripheral region. The central region has a first light transmission band for a wavelength range of a visible light and a second light transmission band for a wavelength range of an infrared light. The peripheral region surrounds the central region. The peripheral region has a third light transmission band for the wavelength range of the infrared light and is substantially opaque to the visible light, and an area of one portion of the central region surrounded by the peripheral region is tapered toward the first direction.

Abstract: A display control circuit is capable of adjusting backlight intensity according to image content as well as compensating pixel values of frames for power saving and distortion reduction. The display control circuit includes a threshold determining circuit, a pulse width modulation (PWM) control circuit and a pixel value adjusting circuit. The threshold determining circuit determines a threshold according to a reference value by histogramming a to-be-displayed frame. The threshold is smaller than an upper limit of the pixel values, and a proportion of the number of pixel values between the threshold and the upper limit which occupy a total pixel number is lower than the reference value. The PWM control circuit generates a PWM signal for controlling a backlight luminance according to the threshold. The pixel value adjusting circuit adjusts the values of the pixels according to the threshold.

Abstract: An image processing method is disclosed according to one embodiment of the present invention. The method comprises receiving an image according to a first timing signal having at least one first active pixel time period, at least one first horizontal blanking time period and a first vertical blanking time period; and outputting the image according to a second timing signal having at least one second active pixel time period, at least one second horizontal blanking time period and a second vertical blanking time period. A pixel number corresponding to the first active pixel time period equals to a pixel number corresponding to the second active pixel time period. The second horizontal blanking time period is less than the first horizontal blanking time period. The second vertical blanking time period is larger than the first vertical blanking time period.

Abstract: A dithering method and associated apparatus is provided. The method synthesizes a dither pattern including a plurality of elements. At least two of the plurality of elements are of a same value, and at least two of the elements of the same value respectively associate with different driving polarities to prevent flickering. While sub-pixel data of a sub-pixel corresponds between two predetermined color levels of the sub-pixel, a color level displayed by the sub-pixel is determined from the two predetermined color levels according to a sum of the sub-pixel data and the element corresponding to the sub-pixel.
