| 20080284870 | IMAGE PICKUP APPARATUS AND CONTROL METHOD THEREFOR - An image pickup apparatus capable of performing favorable focusing operation when image signals are read out from an image pickup device at a high speed while flickers are occurring. Flickers are detected from image signals outputted from the image pickup device, while the image signals outputted from the image pickup device is stored. The image signals outputted from the image pickup device and the image signals stored in a first memory are synthesized depending on the flicker detection result. A position of a focus lens is adjusted by selectively using any one of the image signals outputted from the image pickup device and the synthesized image signal. When the image pickup device performs reading images in a cycle longer than a flicker cycle, image synthesis is performed depending on the brightness of the image signals outputted from the image pickup device. | 11-20-2008 |
| 20090128660 | LIGHT SOURCE FREQUENCY DETECTION CIRCUIT USING BIPOLAR TRANSISTOR - An apparatus for measuring the power frequency of a light source includes a photo-sensitive transistor, a modulators and a logic unit. The photo-sensitive transistor generates an electrical signal that is responsive to light incident thereon from the light source. The modulator generates a modulated signal based on the electrical signal that toggles at a rate substantially proportional to the power frequency of the light source. The logic unit is coupled to receive the modulated signal and determine its toggling frequency. | 05-21-2009 |
| 20120002074 | IMAGE PROCESSING APPARATUS, SIGNAL PROCESSING APPARATUS, AND PROGRAM - An apparatus and a method which enable effective removal of flicker are provided. Under an illumination environment such as a fluorescent lamp with luminance variation, flicker that occurs in images shot with an X-Y address scanning type imaging device such as a CMOS is effectively removed or reduced. The integral value of the row-by-row signal intensity of an image to be corrected from which to remove flicker is calculated, and this integral value is used to detect flicker components contained in individual rows of an image frame. The detected flicker components represent data according to the actual flicker waveform of the illumination, and a correction process is executed using flicker correction coefficients formed by an anti-phase pattern of the flicker components. Effective flicker removal becomes possible through this process. | 01-05-2012 |
| 20140253755 | IMAGING APPARATUS - If a flash detector determines that a video signal generated by an imager is affected by a flash when an electronic shutter is used, the imager generates the video signal representing a preceding unit image determined to be affected by the flash, and then a video signal representing a succeeding unit image that is consecutively exposed from the previous unit image for the same exposure period as the preceding exposure period, by setting a next time of a read signal to be earlier than a preceding time. A flash corrector uses the video signal representing the preceding unit image determined to be affected by the flash, and the video signal representing the succeeding unit image following the preceding unit image to generate a video signal in which a bright portion having a band shape affected by the flash is corrected. | 09-11-2014 |
| 20140333799 | IMAGING APPARATUS, METHOD FOR CONTROLLING THE SAME, AND STORAGE MEDIUM - An imaging apparatus has a first mode in which a detection unit detects a light amount change characteristic from an object between first and second exposures of an imaging unit during a continuous shooting and a determination unit determines an exposure timing of the second exposure based on the detected light amount change characteristic. | 11-13-2014 |
| 20150312459 | IMAGING APPARATUS AND CONTROL METHOD - In one or more embodiments, exposure control of an image sensor is performed based on a movement characteristic of a shutter configured to be movable to a position at which the image sensor is shielded from light and to a position at which the image sensor is not shielded from light. A moving speed of the shutter may change during movement, and a light amount change characteristic of light from an object may be calculated by a calculation unit. In one or more embodiments, the calculation unit calculates a timing when a light from an object satisfies a predetermined condition. | 10-29-2015 |
