Publication number: 20020087984Abstract: In an apparatus for receiving digital television broadcast, a user may be safeguarded from misconception that the apparatus may be in disorder. When a channel for receipt is commanded in the apparatus for receiving digital television broadcast, the number of the channel is acquired at step S11. It is verified at step S12 whether or not the channel so selected has been set as being a channel for reception. If the result of check is affirmative, a picture for the channel is displayed at step S14. If otherwise, that is if the channel selected has not been set as the channel for reception, the effect that the channel cannot be viewed is displayed at step S15.Type: ApplicationFiled: November 28, 2001Publication date: July 4, 2002Inventors: Satoru Maeda, Kazushige Tsurumi, Yushi Sayama, Munehiro Yoshikawa, Ayumi Mizobuchi, Takaaki Miura, Katsuhisa Takata, Yusuke Fujimaki

Patent number: 4903134Abstract: In an automatic focusing circuit of a video camera, automatic focusing operation is performed by a focus evaluating value formed in response to a video signal obtained by an image sensing circuit (4). A first focusing motor control circuit (15) controls the rotation of a focusing motor (3) so that a focusing lens (1) is once fixed in the position where the focus evaluating value takes the maximum value. A second focusing motor control circuit (17) changes the focusing motor (3), by a predetermined very small amount, to determine the slope of the focus evaluating value, which change is repeated until inversion of the slope, that is, the maximal point is detected. As a result, the position of the focusing lens is corrected at the maximal point of the focus evaluating value. When the correction amount exceeds a predetermined value, first automatic focusing operation by the first focusing motor control circuit (15) is resumed.Type: GrantFiled: December 9, 1988Date of Patent: February 20, 1990Assignee: Sanyo Electric Co., Ltd.Inventors: Hirotsugu Murashima, Satoru Maeda, Shunji Hirano

Patent number: 4853789Abstract: In an automatic focusing circuit of a video camera, an automatic focusing operation is performed by a focus evaluating value produced in response to a video signal obtained in an image sensing circuit (4). A focusing motor control circuit (14) controls rotation of a focusing motor (3) so that a focusing lens (1) is once fixed in the position where the focus evaluating value takes the maximum value. Then, a control circuit (14) resumes the automatic focusing operation after a lapse of a second time period when it is determined that the focus evaluating value was decreased to a predetermined level during a first time period and maintained the level over the second time period, and does not resume the automatic focusing operation when it is determined that the focus evaluating value did not maintain the level.Type: GrantFiled: February 16, 1988Date of Patent: August 1, 1989Assignee: Sanyo Electric Co., Ltd.Inventors: Hirotsugu Murashima, Satoru Maeda
