Abstract: An apparatus for controlling a head lamp for vehicles which includes an image providing unit which acquires image information in front of a subject vehicle through a camera module and an information processing unit which detects a position of a vehicle in front of the subject vehicle based on the image information to determine a high beam avoidance area. In particular, a light source unit irradiates a high beam and a low beam in the head lamp based on the driving information acquired. In particular, the high beam avoidance area is represented by an angular range, and is within a range of 90 degrees with respect to a forward direction of the subject vehicle, and the angular range of the high beam avoidance area is determined based on outermost vehicles on left and right sides in the image information.

Abstract: Disclosed are multi-channel PWM (Pulse Width Modulation) apparatuses and methods for modulating PCM-based multi-channel audio signals read from an optical medium into PWM-based multi-channel audio signals. A multi-channel PWM apparatus and method can reduce noise from amplifying PCM-based audio signals having adjacent signal processing paths. The multi-channel PWM apparatus and method selectively vary only gains of some channels in a plurality of channels in order to allow an audio signal applied to a pulse width modulator to have a different level in individual channels in a prescribed system condition (e.g., overload). The multi-channel PWM apparatus can selectively enable a subset among a plurality of pulse width modulators to reduce unnecessary driving and noise. Thus, preferred embodiments can reduce or prevent deterioration of output audio signals.
