A CMOS image sensor for a camera assembly is provided, having a sensor die with opposing faces, an upper face, and a lower face. On the upper face, the sensor die is provided with a sensor array, an analog-to-digital conversion module, a digital logic circuit, and a timing and clock control circuit. The sensor array is substantially centered on the sensor die. The analog-to-digital conversion module is split into two submodules. Each submodule is disposed adjacent to the sensor array and positioned on opposing sides of the sensor array. The digital logic circuit forms a first row. The timing and clock control circuit and the analog signal processing circuit are adjacent and form a second row. The first and second rows have similar dimensions and are disposed on opposite sides of the sensor array.

There is provided in one embodiment an apparatus having an image sensor array. In one embodiment, the image sensor array can include monochrome pixels and color sensitive pixels. The monochrome pixels can be pixels without wavelength selective color filter elements. The color sensitive pixels can include wavelength selective color filter elements.

An imaging apparatus includes: an imaging sensor; a lens mount to which a lens is attached; and a processor is configured to read out an imaging signal from the imaging sensor and generate a raw image. The processor is configured to determine a length of a second focal length in a second direction which intersects with an extending direction of an optical axis of the lens and a first direction which intersects with the extending direction, relative to a first focal length in the first direction, and make a resolution ratio, which is a ratio of a resolution of the raw image in the first direction to a resolution of the raw image in the second direction, higher than a resolution ratio of the imaging sensor in a case where the second focal length is longer than the first focal length.

An imaging apparatus according to the present invention includes an imaging unit configured to capture an image of an arbitrary object and output a plurality of image signals with different exposures and a focus detection signal, and a composition unit configured to compose the plurality of image signals with different exposures output from the imaging unit and output the composed image signal. In a case of time-sequentially capturing images in succession, the imaging unit outputs the focus detection signal instead of the plurality of image signals at a predetermined timing. The composition unit composes image signals by using image signals in a time-sequentially adjacent different timing instead of image signals missing at the predetermined timing.

A vehicle occupant monitoring system, OMS, comprises: an image acquisition device comprising an image sensor and a lens assembly having a varying transmissivity across a field of view of the image sensor; at least one infra-red, IR, light source disposed within a cabin of the vehicle and being configured to illuminate at least one occupant of the vehicle with varying illumination across the field of view of the image sensor; and an image processing pipeline configured to obtain and pre-process an image acquired from the image sensor in accordance with a lens shading map and a cabin illumination map in order to compensate for both the varying transmissivity and the varying illumination in order to provide a more uniformly illuminated image to a controller for further analysis.
