  "textContent": "A control apparatus (100) for a vehicle lamp (210) includes a receiver (102) and a controller (104). The receiver (102) receives detection values of an acceleration sensor (110). The controller (104) plots the detection values to derive a straight line and outputs an adjustment signal that instructs to adjust an optical axis (O) of the vehicle lamp (21) based on a gradient of the straight line. A vehicle attitude angle (¸ v ) can be estimated from the gradient of the straight line. If the detection values to be used to derive the straight line include a detection value that is obtained when the vehicle (300) is in a predetermined traveling state which lowers an accuracy of estimation of the vehicle attitude angle (¸ v ) from the gradient of the straight line, the controller (104) derives the straight line with excluding this detection values and adjusts the optical axis (O), avoids an output of the adjustment signal, or outputs a maintenance signal.",
