A video processing apparatus includes a light irradiation unit, a video acquisition unit, a motion detection unit, and an imaging control unit. The light irradiation unit irradiates a face of an object of shooting with light. The video acquisition unit acquires a video capturing the face of the object of shooting. The motion detection unit detects a speed of motion of at least a portion of the face in the video acquired by the video acquisition unit. The imaging control unit changes an open period of a shutter in the video acquisition unit and a light emission intensity of the light irradiation unit based on the speed detected by the motion detection unit.

A spray pattern imaging apparatus, and method of operation, is described herein. The method is carried out by the spray pattern imaging apparatus that includes a frame having a set of known aspects corresponding to a first dimension and a second dimension within a first plane. The spray pattern imaging apparatus also includes a light source generating a planar light pattern within a substantially same plane as the first plane of the frame. The set of known aspects facilitate both correcting an image distortion and a scaling of a spray pattern image generated by an image acquisition device during a spray application by a nozzle positioned in a physical relationship with the planar light pattern such that spray particles emitted from the spray nozzle pass through the planar light pattern while an initial image is acquired by the image acquisition device.
