Integrated circuit for processing digital signals in video camera having electronic zooming function
Patent number: 5331411Abstract: An output from a solid state image sensing device spatially modulated by a color filter is A/D converted and stored in a field memory. Digital signals read from the field memory during electronic zooming are successively delayed by 1H period by means of first, second and third 1H delay elements connected in series. The output from the field memory and outputs from the first, second and third 1H delay elements are separated into luminance components and line sequential color components by first to fourth Y/C separating circuits, respectively. A first set of three primary color signals are calculated based on outputs from the first, second and third Y/C separating circuits, and a second set of three primary color signals are calculated based on outputs from the second, third and fourth Y/C separating circuits.Type: GrantFiled: October 29, 1991Date of Patent: July 19, 1994Assignee: Sanyo Electric Co., Ltd.Inventors: Kiyotada Kawakami, Masao Takuma, Tooru Asaeda, Tooru Yamamoto, Haruhiko Murata, Hirotsugu Murashima, Tohru Watanabe, Masashi Honzawa, Keiichi Tanii -
Patent number: 5249058Abstract: The present invention relates to an automatic focusing camera in which an automatic focusing operation is performed by detecting a high frequency component of a video signal obtained from an image sensor device at every predetermined period, and has a theme that the automatic focusing operation can be performed within an extremely short time. To this end, by a search means, a focus lens is moved from a first position to a second position with relatively coarse steps to obtain a focus evaluating value for each step. In a first method, after the focus lens is moved to the vicinity of a lens position corresponding to a maximum focus evaluating value obtained by the search means, the focus lens is moved with small incremental steps to find a true maximum focus evaluating value.Type: GrantFiled: January 12, 1993Date of Patent: September 28, 1993Assignee: Sanyo Electric Co., Ltd.Inventors: Haruhiko Murata, Hirotsugu Murashima

Patent number: 5140408Abstract: Supplied selectively to a recording system circuit of a VTR are a first component signal comprising three primary color signals R, G and B and a second component signal comprising a luminance signal Y and two types of color difference signals P.sub.B and P.sub.R. The first and the second component signals pass through a group of LPFs (1, 2, 3) having the same pass characteristics and then are A/D converted at the same sampling clock. The component signal converted into a digital signal is applied to a matrix circuit 11. Respective coefficients of the matrix circuit are switched according to a type of the inputted component signal, and as a result, a second digital component signal is always outputted at a fixed delay time from the matrix circuit. Two color signal data which are over-sampled included in the second digital component signal are applied to decimation digital filters 14 and 15 to reduce data densities thereof.Type: GrantFiled: February 8, 1990Date of Patent: August 18, 1992Assignee: Sanyo Electric Co., Ltd.Inventors: Osamu Kaite, Takahiro Yuchi, Hirotsugu Murashima

Patent number: 4987491Abstract: A reproduced video signal of a VTR is applied to a jitter compensation circuit (100). The applied reproduced video signal is A/D converted by a phase modulated clock and after subjected to the adjustment of timing, the signal is written into a memory (4). A burst signal period is specified based on a timing of a horizontal synchronizing signal in the reproduced video signal and a jitter amount is detected based on a sampling phase of the A/D converted burst. Jitter compensation data is calculated based on this jitter amount. On this occasion, latest jitter compensation data is obtained based on the detected jitter amount and the jitter compensation data one horizontal period before. A timing for starting to write the A/D converted video data into the memory is defined based on high-order data of the calculated jitter compensation data, thereby cancelling large jitter components.Type: GrantFiled: January 12, 1990Date of Patent: January 22, 1991Assignee: Sanyo Electric Co., Ltd.Inventors: Osamu Kaite, Takahiro Yuchi, Hirotsugu Murashima

Patent number: 4967279Abstract: An automatic focusing circuit in a video camera separates a high frequency component from the video signal obtained in an image sensing circuit 4 for every field. After the separated high frequency component is integrated in an integration circuit 10, the result is converted into a digital value by an A/D converter 11 and is applied to a holding circuit 12 as a focus evaluating value. The holding circuit 12, which comprises first to fifth memories coupled in series, always holds the newest successive five focus evaluating values. The largest focus evaluating value is detected by the maximum value detecting circuit 18 for every field and is applied to a memory 19. The maximum value is compared with the maximum value one field before held in a memory 20 in a comparator circuit 21. If the newest maximum value in the memory 19 is decreased, a focusing motor control circuit 22 inverts the rotational direction of the focusing motor 3.Type: GrantFiled: June 5, 1987Date of Patent: October 30, 1990Inventor: Hirotsugu Murashima

Patent number: 4922346Abstract: In an automatic focusing apparatus of a video camera, a first focus evaluating value which steeply changes and a second focus evaluating value which gently changes relative to the position of a lens, are detected in response to a video signal obtained in an image sensing circuit (4). A switching circuit (19) alternately selects the first and second focus evaluating values every one field to apply the same to in-focus state detecting circuits (20, 21), respectively. The in-focus state detecting circuits (20, 21), together with a focusing motor control circuit (10), perform an automatic focusing operation by hill-climbing control. In addition, a calculating circuit (22) calculates the relative ratio of the first focus evaluating value to the second focus evaluating value.Type: GrantFiled: June 24, 1988Date of Patent: May 1, 1990Assignee: Sanyo Electric Co., Ltd.Inventors: Masaru Hidaka, Hirotsugu Murashima, Masao Takuma, Toshinobu Haruki, Kenichi Kikuchi

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
