    摘要： An imaging device includes a detector that repeatedly carries out a series of operation of generating an evaluation value to evaluate the degree of focusing of a position after driving of a lens toward one end part in the drive range of the lens, and detects the evaluation value of a position that is closer to the end part than the position of the evaluation value of the highest degree of focusing and is immediately adjacent or adjacent across a predetermined number of positions to the position of the evaluation value of the highest degree of focusing. The imaging device further includes a drive controller that makes the series of operation be repeatedly carried out toward the other end part in the drive range of the lens, and drives the lens to a position of a degree of focusing not smaller than the detected evaluation value.

    摘要： An optical scanning projection module includes a scanning light component including a plurality of sub light sources and at least one light-splitting element, a main light reflective element, a scanning element and a photosensitive element. Sub light beams of the sub light sources are converged to form a main light beam. One of the sub light beams travels to the light-delivering element to form a partial reflective light beam and a partial penetrating light beam. With a scanning manner, the partial reflective light beam or the partial penetrating light beam is reflected by the scanning element to be an inspection light, and the main light beam is reflected by the scanning element to be a projection light. The photosensitive element outputs a sensing signal according to the inspection light. Thus, the optical scanning projection module controls the operation of the scanning light component according to the sensing signal.

    摘要： A hybrid connected component labeling process for analyzing digitized or binary images includes the following steps. Firstly, a forward scan is executed to assign a forward label to each foreground pixel in the image. Then, a backward scan is executed to assign a backward label to each foreground. The backward labels are rearranged and label connection is recorded. A label allocation table including final labels and reference labels is provided for recording the use of the labels. When an object is considered as noise, the label corresponds to the pixels of the object is released by updating the label allocation table.

    摘要： A broadcasting receiving apparatus includes a liquid crystal display device including a liquid crystal cell in which a liquid crystal layer that is twist-aligned at 90° and sandwiched between a pair of substrates, first and second polarizing layers arranged to sandwich the cell therebetween so that their absorption axes are set in parallel with directions crossing aligning treatment directions of the substrates at 45°, and viewing angle compensating plates respectively arranged between the polarizing layers and the cell. A total value of retardations in a thickness direction, defined as a value of a product of a phase difference within a plane perpendicular to substrate surfaces of the cell and a layer thickness, of optical layers present between the polarizing layers is set to a value that substantially cancels out a retardation in a liquid crystal layer thickness direction when a saturation voltage is applied to the liquid crystal layer.
