  • Patent number: 9420261
    Abstract: Left- and right-eye captured images are output upon reception of light beams having passed through one imaging optical system, and the difference, between the left- and right-eye captured images, of each of subjects included in the left- and right-eye captured images is detected. An extraction image extracted from a region which includes a main subject and has a predetermined size is output for each of the left- and right-eye captured images. At this time, the region is set so that the difference, between the left- and right-eye captured images, of a subject which is different from the main subject and included in both the extraction images has a predetermined value.

  • Patent number: 8830371
    Abstract: An image pickup apparatus capable of reducing the influence of dark current noise to thereby obtain excellent image quality, even when the dynamic range is expanded under a photographing condition. In an image pickup element of a CMOS image sensor of the apparatus, a photo diode (PD) generates and accumulates electric charge according to an optical input, and a floating diffusion portion (FD) accumulates the electric charges. A charge holding portion (MEM) is disposed between PD and FD. A first transfer transistor selectively separates and connect between PD and MEM, and a second transfer transistor selectively separates and connects between MEM and FD. A system control circuit sets an operation mode to either a first operation mode in which PD and MEM are separated or a second operation mode according to photographing conditions for shooting an object in which PD and MEM are connected.
