Patent number: 6621927Abstract: A boundary position detection apparatus in which the position of an imageless part (containing no meaningful image information) lying at the upper part or/and the lower part of a picture is precisely detected from a video signal. A line decision circuit decides whether each of lines constituting the picture belongs to an image part (containing meaningful image information) or to the imageless part. A boundary decision circuit decides the boundary between the image part and the imageless part. A time integration circuit integrates the detected boundary positions temporally, and determines a final boundary position. A detection control circuit finds an image-part region from the final position, detects the average luminance of the region and controls the integrating time interval of the time integration circuit with the average luminance.Type: GrantFiled: November 16, 1999Date of Patent: September 16, 2003Assignee: Hitachi, Ltd.Inventors: Takayuki Mori, Nobufumi Nakagaki, Yumi Bando, Shinobu Torikoshi, Sunao Suzuki, Toshinori Murata

Patent number: 5534934Abstract: To provide an image which is matched with an aspect ratio of a screen of a display unit by compressing and enlarging the whole of the image to a desired size. A video signal is sequentially written into a field memory in response to a write clock from an input terminal. A clock generating circuit supplies the field memory with a read clock having a frequency which is about 4/3 times as high as that of the write clock. A vertical enlargement control circuit reads a video signal from the field memory with a line period corresponding to a magnification factor and inhibits writing to a one-line memory with the same period to provide a line delayed output for an output signal from the field memory. A vertical interpolating circuit generates a scanning line signal by an interpolation operation in accordance with a control signal from the vertical enlargement control circuit.Type: GrantFiled: June 16, 1994Date of Patent: July 9, 1996Assignee: Hitachi, Ltd.Inventors: Kenji Katsumata, Shigeru Hirahata, Toshinori Murata, Haruki Takata, Shinobu Torikoshi, Takanori Eda, Kouichi Ishibashi
