Filed: 1988-09-05
Abstract: PURPOSE:To correctly and surely detect the inclination of a document by obtaining the histogram of the maximum total value of black picture elements exceeding a threshold, and detecting the value of the inclination for which the histogram is obtained and which is determined by a black picture element histogram generating means as the inclination of the document. CONSTITUTION:The black picture element histogram generating means 1 scans document scanning picture data stored in a picture memory along plural inclinations determined beforehand, and generates the histogram of the number of the black picture elements for every inclination. Next, a threshold exceeding part detecting means 2 measures a part exceeding the predetermined threshold. Then, the total of the black picture elements exceeding the threshold for every histogram is obtained by a threshold exceeding part totaling means 3, and the histogram of the maximum total value of the black picture elements exceeding the threshold is obtained by a document inclination detecting means 4, and its inclination is detected as the inclination of the document. Thus, the inclination of the document on an original is detected correctly, independent of the inclination of the inputted original.

IPC: G09F9/35
Filed: 1991-08-08
Abstract: PURPOSE:To increase the contrast of the liquid crystal display device disposed with an angle-of-view expanding plate on the front surface side of a liquid crystal display panel. CONSTITUTION:The angle-of-view expanding plate 5 formed by superposing many transparent thin films 21 consisting of an acrylic resin, etc., in the thickness direction thereof to a plate form is disposed on the front surface side of the liquid crystal display panel 1.
