Circuity of the circuit board (i) provides electrical power to the camera via the flexible electrical connector, (ii) controls the camera via the flexible electrical connector and (iii) receives image data from the camera via the flexible electrical connector. With the camera module mounted at the windshield, the circuit board is tilted at an angle relative to the principal lens axis of the lens of the camera.

Vehicular vision system with windshield mounted camera

A vehicular vision system includes a camera module configured for mounting at an in-cabin portion of a windshield of a vehicle and including a circuit board and a camera that views forward of the vehicle and through the windshield. The camera includes a CMOS imaging sensor array. A data processor is operable to process image data captured by the CMOS imaging sensor array. Image data captured by the CMOS imaging sensor array is encoded by a data encoder chip. Image data captured by the CMOS imaging sensor array that is encoded at the data encoder chip is carried as a data stream from the camera module to the data processor via a cable. Communication via the cable between the camera and the data processor is bidirectional. The data processor is located in the vehicle remote from the camera module.

IMAGING PIXELS WITH STORAGE CAPACITORS

An image sensor may include an array of imaging pixels and row control circuitry. Each imaging pixel may include a photodiode, a floating diffusion region, a transfer transistor configured to transfer charge from the photodiode to the floating diffusion region, a dual conversion gain transistor coupled to the floating diffusion region, and a storage capacitor coupled to the dual conversion gain transistor. The capacitor may have a plate that receives a modulated control signal and the row control circuitry may be configured to modulate the control signal. To reduce image artifacts, the modulated control signal may be modulated low during the integration time of the pixel and may be modulated high during the high conversion gain readout time of the pixel.

Electrochromic filtering in a camera

This application is directed to controlling a camera that includes an electrochromic glass layer. The electrochromic glass layer is disposed in front of a sensor array of the camera and has optical transmission properties that are responsive to voltage applied to the electrochromic glass layer. In accordance with a determination to transition the camera mode to a Day mode, a camera controller generates a first voltage, which is then applied to the electrochromic glass layer to cause the lens assembly to enter a first transmission state. In response to the first voltage, the electrochromic glass layer removes a substantial portion of a predefined band of infrared wavelengths in ambient light incident on the camera, and simultaneously passes by the electrochromic glass layer a substantial portion of visible wavelengths in the ambient light, thereby exposing the sensor array to the substantial portion of the visible wavelengths of the ambient light.
