This disclosure provides systems, methods, and apparatuses for sensing a scene. In one aspect, a device may illuminate the scene using a sequence of two or more periods. Each period may include a transmission portion during which a plurality of light pulses are emitted onto the scene. Each period may include a non-transmission portion corresponding to an absence of emitted light. The device may receive, during each transmission portion, a plurality of light pulses reflected from the scene. The device may continuously accumulate photoelectric charge indicative of the received light pulses during an entirety of the sequence. The device may transfer the accumulated photoelectric charge to a readout circuit after an end of the sequence.

Apparatuses and methods for focusing a camera are disclosed. For example, an apparatus may be coupled to a camera for focusing the camera. The apparatus includes a vision sensor coupled to a processor and configured to capture a view. The processor configured to receive a selection of an area of interest in the view. The apparatus further includes a distance measurement unit coupled to the processor and configured to measure a distance to the area of interest for adjusting the camera's focus.

Provided is a signal processing device including a control unit that acquires distance measurement information on the basis of an addition value obtained by adding together outputs of a plurality of phase difference detection pixels supplied from an imaging element in which the plurality of phase difference detection pixels different in phase difference characteristic is arranged.

Systems and methods directed to a digital rangefinder camera are described. The digital rangefinder camera may include a viewfinder assembly configured to receive a first optical image from a first optical path and a focus ring movement detection assembly configured to detect an amount of movement associated with a focus ring of a lens attached to the digital rangefinder camera. A processing device may be configured to provide a movement signal indicative of the amount of movement associated with the focus ring to an actuator coupled to an optical element, where the actuator moves the optical element and displaces a second optical image from a second optical path directed toward an optical component in the viewfinder assembly. The optical component in the viewfinder assembly is configured to project the first optical image and the second optical image toward a single common viewing position when the first optical image and the second optical image coincide.
