20080218579 | Image Forming Apparatus - An image forming apparatus irradiates a polygon mirror with laser beams from different directions. The polygon mirror reflects the laser beams toward different optical axis directions to scan the laser beams at a predetermined deflection angle. First and second beam detectors are disposed at the beam incident ends in the scanning direction of first and second light scanning sections such that the second beam detector detects the start of the light beam scanning operation at an earlier timing than the first beam detector does. The detection result of the first beam detector is used to set sampling start timing in common between first and second image data. Based on the detection results of the first and second beam detectors, first and second image data are written into a memory, and the first and second laser source sections are controlled based on the image data read out from the memory. | 09-11-2008 |

20140362277 | IMAGING APPARATUS AND CONTROL METHOD FOR SAME - An imaging apparatus includes an imaging element having pixel portions each having a plurality of photoelectric conversion units for each microlens. The imaging element can output a pixel signal depending on a pupil-divided light flux. An image processing LSI processes a video signal based on the pixel signal output from the imaging element. An imaging element control unit controls the operation of the imaging element. An exposure control unit performs exposure control for an optical lens unit and an imaging element. In the first mode, the operation for reading pixel signals from all of the plurality of photoelectric conversion units constituting the pixel portion of the imaging element is performed. In the second mode, the control for reading pixel signals from a part of the plurality of photoelectric conversion units and for stopping a circuit relating to the unused photoelectric conversion units by reading no pixel signal is performed. | 12-11-2014 |
20150078725 | IMAGE CAPTURING APPARATUS, IMAGE CAPTURING SYSTEM, AND CONTROL METHOD FOR THE IMAGE CAPTURING APPARATUS - An image capturing apparatus comprises an image capturing unit that includes an image sensor that has an effective pixel region and a reference pixel region which outputs a reference signal for correcting an output signal of the effective pixel region. In a case where a predetermined condition is satisfied, a reduction unit reduces a data amount of reference pixel region data that corresponds to the reference pixel region in an image data obtained by the image capturing unit. A recording unit records the image data after the processing performed by the reduction unit. | 03-19-2015 |
