Abstract: An image signal processor may include a data receiver configured to receive image data including depth values corresponding to pixels included in an image obtained from a distance measurement sensor. The image signal processor may also include a motion detector configured to detect motion in the image using either a first motion detection method which uses pixels or a second motion detection method which uses preset kernels, based on amplitude of the light source and generate a detection result indicating whether the motion is included in the target image. A noise remover removes noise from the target image using either a first noise removal method which uses previous image data corresponding to previous images or a second noise removal method which uses the image data corresponding to the target image based on the detection result.

Abstract: Provided are an apparatus and a method for measuring a three dimensional shape with improved accuracy. The apparatus includes a stage, at least one lighting unit, a plurality of image pickup units and a control unit. The stage supports an object to be measured. The lighting unit includes a light source and a grid, and radiates grid-patterned light to the object to be measured. The image pickup units capture, in different directions, grid images reflected from the object to be measured. The control unit calculates a three dimensional shape of the object from the grid images captured by the image pickup units. The present invention has advantages in capturing grid images through a main image pickup portion and sub-image pickup portions, enabling the measurement of the three dimensional shape of the object in a rapid and accurate manner.
