Driver Assistance System
The disclosure relates to a driver assistance system for a motor vehicle, such as a truck. The driver assistance system includes an environment camera with an image sensor and an optical system. The driver assistance system also includes an imaging unit and a display element in the interior of the motor vehicle. The environment camera, the imaging unit, and the display element form a digital exterior mirror, where the digital exterior mirror is arranged such that at least two visual field regions, namely a first visual field region and a second visual field region, are mapped with different magnifications.
ON-VEHICLE CAMERA DEVICE
Provided is an on-vehicle camera device that swiftly and accurately detects, in every frame, data line signals of respective bits from imaging elements. This on-vehicle camera device includes a failure-diagnosis processing unit that diagnoses whether the data line signals of imaging element units, are in a fixed state. Furthermore, the imaging element units each include an entire imaging region that is divided into an effective image region and an ineffective image region. Also provided is a diagnosis data region that includes fixation diagnosis data for diagnosing whether the data line signals of the imaging element units in the ineffective image regions are in a fixed state. In an image acquisition period in which image data of the entire imaging region is acquired, and/or an image-calculation processing period, the failure-diagnosis processing unit uses the fixation diagnosis data of the diagnosis data region to perform failure-diagnosis processing.

Sensor control apparatus, sensor control method, and program
A sensor control apparatus includes a readout control circuit and a region setting circuit. The readout control circuit controls an event-driven vision sensor including a sensor array that includes sensors that generate event signals when a change in incident light intensity is detected, in such a manner that the event signals are read out at a first frequency in a first region on the sensor array and that the event signals are read out at a second frequency higher than the first frequency in a second region on the sensor array. The region setting circuit changes at least part of the first region to the second region on the basis of the number of first event signals acquired by the readout in the first region within a given period of time or changes at least part of the second region to the first region on the basis of the number of second event signals acquired by the readout in the second region within the given period of time.
CAPTURING APPARATUS, ELECTRONIC DEVICE, AND PROGRAM
An image-capturing apparatus includes: an image sensor having a first image-capturing region and a second image-capturing region different from the first image-capturing region; and a control unit that displays an image generated by the first image-capturing region and an image generated by the second image-capturing region on a display unit, with a region targeted for setting image-capturing conditions of the image sensor being selectable.
Methods and apparatus for implementing and/or using a camera device
Methods and apparatus for implementing a camera having a depth which is less than the maximum length of the outer lens of at least one optical chain of the camera are described. In some embodiments a light redirection device, e.g., a mirror, is used to allow a relatively long optical chain with a relatively large non-circular outer lens. In some embodiments the light redirection device has a depth, e.g., front of camera to back of camera dimension, which is less than the maximum length of the aperture of the outer lens in the aperture's direction of maximum extent. Multiple optical chains with non-circular outer lenses arranged in different directions may and in some embodiments are used to capture images with the captured images being combined to generate a composite image.
Photoelectric conversion device and photoelectric conversion system
A photoelectric conversion device includes pixels including first and second photoelectric converters, a memory unit, and a transfer unit for transferring signals in the memory unit to a processing unit. The pixels output a first signal based on a signal of the first photoelectric converter, and a second signal based on signals of the first and second photoelectric converters. The transfer unit performs on row-by-row a first transfer period of transferring the first signal in the memory unit and a second transfer period of transferring the second signals held in the memory unit. A column a pixel outputting the first signal transferred during the first period of a first row is arranged is different from a column a pixel outputting the first signal transferred during the first period of a second row is arranged.
