  • Patent number: 10334161
    Abstract: An image processing apparatus includes a system controlling unit including a processor and a memory, the system controlling unit being configured to load and to execute an operation control program stored in the memory. The system controlling unit and the memory are configured to acquire light field data, including a plurality of divided image data, to perform an image processing including color correction processing to each of the plurality of divided image data, and to form image data by combining pixel signals of the plurality of the divided image data. Depths of field of the plurality of divided image data are deeper than those of the formed image data. The system controlling unit controls operation to perform the image processing and to form the image using the processed plurality of divided image data.

  • Patent number: 9030596
    Abstract: A focus detection apparatus which is capable of estimating each of signals from a plurality of split PDs, which are included in a sum signal from split PDs, by performing a computation to thus detect saturation with respect to each split PD. With respect to each unit pixel cell having a plurality of PDs sharing one micro lens, saturation of a pixel signal read out in a non-destructive manner from one of the PDs is detected. Based on a first luminance signal and a sum pixel signal obtained by summing signals output from the PDs, another pixel signal output from another one of the PDs is estimated. Saturation of the estimated pixel signal is detected, and a second luminance signal is generated. Based on the first and second luminance signals, the amount of defocus for an optical unit is calculated.
