A signal receiving end of a digital television includes: an analog-to-digital converter (ADC), converting an input signal from an analog format to a digital format, the input signal including a target signal and an interference signal; a digital gain control circuit, coupled to the ADC, adjusting an amplitude of the target signal according to a gain; a detecting module, coupled to the digital gain control circuit, detecting a variance in the gain to generate a detection value; and a control circuit, coupled to the digital gain control circuit, determining a gain setting parameter according to the detection value. Wherein, the digital gain control circuit further updates the gain according to the gain setting parameter.

Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device comprises an equalizer configured to receive an input signal through a channel and equalize the received input signal and a control circuit configured to determine an equalizer control code in response to a first signal output from the equalizer and output the determined equalizer control code to the equalizer, wherein the equalizer may equalize the received input signal based on the equalizer control code. Accordingly, there is an effect of effectively adapting the equalizer even when a channel environment changes.

Computer-implemented systems and methods herein disclose automatic haze correction in a digital video. A video dehazing module divides a digital video into multiple scenes, each scene including a set of video frames. For each scene, the video dehazing module identifies the dark channel, brightness, and atmospheric light characteristics in the scene. For each video frame in the scene, the video dehazing module determines a unique haze correction amount parameter by taking into account the dark channel, brightness, and atmospheric light characteristics. For each video frame, the video dehazing module also determines a unique haze correction sensitivity parameter by taking into account transmission map values in the scene. The video dehazing module applies the unique haze correction amount parameters and unique haze correction sensitivity parameters to each video frame generate a sequence of dehazed video frames.

An image signal processor accesses raw images from an image sensor. The image signal processor obtains adaptive acquisition control data for the raw images. The adaptive acquisition control data comprises at least one of a luminance value, a contrast value, a gain value, an exposure value, or a white balance value. The image signal processor obtains, in accordance with the adaptive acquisition control data, an indication of whether to use a star trails scene classification for the raw images. The image signal processor transmits, to buffers for storing data in accordance with the raw images, the indication of whether to use the star trails scene classification.
