  • Publication number: 20170026579
    Abstract: Provided is an imaging device that prevents glare resulting from light that leaks out from a subject display area of a display section in an OVF mode. A finder device can be switched between the OVF mode and an EVF mode. A subject display area and an information display area are set in an EVFLCD. In the OVF mode, nothing is displayed in the subject display area of the EVFLCD, and an information image is displayed in the information display area. An EVF shutter is set such that the light transmittance of a first area, which corresponds to the subject display area, becomes a low transmittance and the light transmittance of a second area, which corresponds to the information display area, becomes a high transmittance. The first area, which is set at low transmittance, blocks light that leaks from the subject display area.

  • Publication number: 20170013182
    Abstract: Provided is an imaging device capable of expanding the dynamic range and eliminating differences in level occurring in low luminance regions between segments having different transmittances. A number of high luminance pixels calculation section calculates the number of high luminance pixels for each segment, on the basis of pre-image data obtained through pre-imaging while all the segments of a light modulation element have high transmittances. A main control section determines, as a dimming target segment, a segment having a number of high luminance pixels equal to or greater than a first number of pixels. A low luminance pixel specifying section specifies low luminance pixels among the pixels corresponding to the dimming target segment. A gain correction section performs gain correction on pixel signal values of the low luminance pixels, with a gain value corresponding to a ratio of the high transmittance to the low transmittance.

  • Patent number: 8169511
    Abstract: After an end of exposure, a data level of OB signals that are imaging signals output from OB portion 400 are sampled by a CDS circuit 6 twice, to artificially generate two OB signals from each OB signal. Thereby, assuming that the total number of OB signals required to stabilize the black level in the clamp circuit 9 is n, the black level can be stabilized before it is started to output effective signals that are imaging signals from effective pixel portion 200 even if the number of OB signals output from the OB portion 400 is 1/n (in the case where pixel mixing or pixel thinning is performed, or in the case where the number of photoelectric conversion elements in the OB portion 400 is less than n). Accordingly, it is possible to prevent the image degradation by suppressing a wrong black level.
