  • Publication number: 20170359533
    Abstract: An image pickup apparatus which is capable of, even when a flash band appears during a zooming operation, properly compensating for the flash band to generate a post-compensation image having no different levels of luminance. A lens unit has a zoom function. Image information generated based on image signals output from an image pickup device, which sequentially starts exposure and sequentially reads out signals for each row of pixels, is held in a memory unit. Based on the image information, the flash band caused by an external flash and extending across a plurality of frames is detected, and frames in which the flash band was detected are corrected to obtain an image having no different levels of luminance. The frames are corrected according to a calculated zoom change ratio of the lens unit when the zoom change ratio does not fall inside a first range determined in advance.

  • Publication number: 20170257592
    Abstract: A signal processing apparatus comprising: an analog-digital converter that uses reference signals having different slopes from each other; a supply unit that supplies analog signals of predetermined different output levels; and a calculation unit that calculates a slope ratio and an offset amount between the plurality of different slopes for correcting a converted digital signal based on digital signals respectively obtained by converting the analog signals of the different output levels using the reference signals. In a case where the conversion is performed using a reference signal with a steeper slope, the supply unit supplies at least one high level analog signal whose level is higher than a case where the conversion is performed using a reference signal with a gentler slope, and a digital signal obtained by converting the high level analog signal is further used when calculating the slope ratio.

  • Publication number: 20170078600
    Abstract: An image capturing apparatus comprises: an image sensor which has a plurality of pixels; and a plurality of processing circuits which correct images of different frames output from the image sensor. Each processing circuit includes: a first detection circuit which performs defective pixel detection on a portion of a region of the plurality of pixels which is different from portions of the region on which the other processing circuits perform defective pixel detection; and a memory which stores information on defective pixels for the entire region obtained by combining information on defective pixels detected by the first detection circuit and information on defective pixels obtained by the other processing circuits. Further, each processing circuit corrects the image of each frame output from the image sensor, using the information on defective pixels for the entire region stored in the memory.
