Patent number: 7336269Abstract: A control circuit and a method discharging capacitor/transistor, for a liquid crystal display (LCD), are provided. The control circuit includes a signal-off detector and an all-gate-on delay cell. When an LCD power-off signal is detected, a first control signal is transmitted to a power supply module for turning off power except the gate-on voltage, and turning off VGH after a specific delay time. A second control signal is also transmitted to the gate-on-delay cell, so that all gates of the pixel transistors are turned on after a second specific delay time. The charges on the pixel transistor are discharged via a source thereof before the gate-on voltage decreases below a threshold value, such that a residual image phenomenon caused by heterogeneous filming fabrication is reduced.Type: GrantFiled: September 24, 2004Date of Patent: February 26, 2008Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Hsin-Chung Huang, Juin-Ying Huang, I-Cheng Chen

Patent number: 7336301Abstract: A solid-state image pickup apparatus includes a solid-state image sensor in which photosensitive cells, each consisting of a main and a subregion and including an optical opening, are arranged in a bidimensional array. A system controller adjusts the exposure times of the main and subregions in dependence upon the direction and amount of a sensitivity error in the vertical direction relative to an accurate optical opening. A timing signal generator feeds a timing signal to a driver in response to a control signal output from the system controller. The driver feeds, in response to the timing signal and a control signal also output from the system controller, the image sensor with a drive signal relating to the opening/closing of a mechanical shutter, thereby causing the above exposure times to end at the same time. Therefore, signal charges output from the main and subregions are free from errors.Type: GrantFiled: August 19, 2003Date of Patent: February 26, 2008Assignee: FUJIFILM CorporationInventors: Kazuya Oda, Hirokazu Kobayashi

Patent number: 7336302Abstract: A frame memory device is employed in a digital camera, for example, to output raster-scanned digital color image signals at lower resolution than that of original image signals. The order of sequentially received original raster-scanned digital color image signals is rearranged, and the rearranged signals are sequentially stored in a memory having a two-dimensional address structure such that vertical addresses represent the order of entry of respective scan lines that constitute the image signals and horizontal addresses represent the order of entry of respective signals that belong to each of the scan lines. The stored rearranged signals are subsampled and read out while skipping horizontal and vertical addresses of the memory at regular intervals. The image signals may comprise YCBCR color signals having a sampling ratio of 4:2:2. Sequentially received C signals in the order of CB?CR?CB?CR, for example, are rearranged in the order of CB?CB?CR?CR.Type: GrantFiled: January 23, 2004Date of Patent: February 26, 2008Assignee: Nikon CorporationInventor: Toshihisa Kuroiwa

Patent number: 7336306Abstract: A solid-state image sensor includes photodiodes, which constitute pixels, shifted in position from each other and red (R), green (G) and blue (B) filter segments fitted on the photodiodes in a preselected pattern. R transfer gates, G transfer gates and B transfer gates each are connected to a particular vertical transfer electrode. Particular vertical drive pulses are fed to the electrodes to drive the transfer R, G and B transfer gates. Photodiode read pulses are applied to each of the electrodes at a particular timing on the basis of image signals output from the image sensor. Consequently, a signal charge generated in each photodiode is shifted to a particular vertical transfer path via the R, G or B transfer gate in accordance with color-by-color exposure time.Type: GrantFiled: November 26, 2002Date of Patent: February 26, 2008Assignee: FUJIFILM CorporationInventor: Kazuya Oda

Patent number: 7336308Abstract: Voltage signals outputted from a CCD are subjected to correlated double sampling processing by a correlated double sampling circuit (CDS), after which digital gain processing is carried out at a gain control amplifier (GCA). A gain difference between G color signals and R/B color signals outputted from the CCD is caused by a difference between a G exposure duration tG and an R/B exposure duration tR/B. When the value of a ratio between the tG and the tR/B falls below a predetermined value, the GCA applies digital gain for compensating for the gain difference by multiplying respective signal values of R, G and B by gain correction coefficients as follows: (gain compensation coefficient ?)=(G exposure duration tG)/(R/B exposure duration tR/B)=(G exposure duration tG)/((G exposure duration tG)+(exposure duration difference ?t)).Type: GrantFiled: February 27, 2003Date of Patent: February 26, 2008Assignee: FUJIFILM CorporationInventor: Naoki Kubo

Patent number: 7336311Abstract: The invention disclosed is directed to a method and apparatus which allows a “rolling shutter” type of read out sequence in a pixel array that is read using a double sampling technique by having the rows of pixels reset a second time in each of their cycles for a second sampling while the rows are being accessed for reading. In this way, each pixel is sampled to compare its voltage level after integration to its voltage level as it is reset. In accordance with the present invention, the row access signal or a signal that is used to generate the row access signal, is used to generate a second reset signal at the correct time while the row is being accessed. The invention is particularly applicable to image sensors having light sensitive elements that are CMOS pixels, and in particular three transistor pixels.Type: GrantFiled: September 30, 2005Date of Patent: February 26, 2008Assignee: Psion Teklogix Systems Inc.Inventor: Michael Pearson

Patent number: 7336312Abstract: A charge-coupled imager includes an imaging section, a read-out section, and a way to reduce the number of charge packets for every row read. The imager is switchable between at least two read-out modes. The imaging section includes image elements arranged in a two-dimensional pattern. The read-out section includes at least a first horizontal CCD channel disposed beside the two-dimensional pattern, a second horizontal CCD channel and vertical CCD channels interlineated within the pattern of image elements. The imager is operable so that every image element of a row is individually readable in a first read-out mode using the first horizontal CCD channel comprising n charge storage locations. The imager is further operable in a second read-out mode so that a lower horizontal sampling frequency is read from the read-out section than in the first read-out mode using a second horizontal CCD channel comprising fewer storage locations than n.Type: GrantFiled: June 13, 2002Date of Patent: February 26, 2008Assignee: DALSA CorporationInventors: Jan Theodoor Jozef Bosiers, Agnes Catharina Maria Kleimann, Laurent Louis Daniel Le Cam

Patent number: 7336313Abstract: This invention has as its object to integrate and simplify a communication interface, and to attain a size reduction of a camera housing and a cost reduction. To accomplish this, a digital camera transfers a control signal that controls the operation of at least one strobe device, and an image signal output from an image sensing means via a single USB cable. Upon making an image sensing operation that requires strobe emission of the strobe device, transfer of the image signal is suspended, and a control signal for the strobe device is preferentially transferred.Type: GrantFiled: February 4, 2003Date of Patent: February 26, 2008Assignee: Canon Kabushiki KaishaInventors: Gaku Watanabe, Masayoshi Sekine
