A vehicle body area detection unit detects a vehicle body area of a vehicle from an image signal. A license plate area detection unit detects a license plate area of the vehicle from the image signal. A vehicle body area image processing unit performs processing of the image signal corresponding to the detected vehicle body area. A license plate area image processing unit performs processing different from the processing of the image signal corresponding to the vehicle body area on the image signal corresponding to the detected license plate area. A synthesis unit synthesizes the processed image signal corresponding to the vehicle body area and the processed image signal corresponding to the license plate area.

Pulsed fluorescence imaging in a light deficient environment is disclosed. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The system includes a controller configured to synchronize timing of the emitter and the image sensor. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises electromagnetic radiation having a wavelength from about 770 nm to about 790 nm or from about 795 nm to about 815 nm.

An image capturing apparatus including the following elements is disclosed. An optical bandpass filter causes visible light and near-infrared light to selectively pass through. An image capturing element outputs a first signal indicating light intensity of the visible light and the near-infrared light and a second signal indicating light intensity of the near-infrared light. A subtractor outputs a third signal by subtracting the second signal from the first signal. A multiplier outputs a fourth signal at a signal level not more than the signal level of the second signal by multiplying the second signal by a control value. An adder outputs an image signal by adding the fourth signal to the third signal. A luminance matrix circuit outputs luminance information on the visible region of the image signal. A luminance level determination circuit supplies the multiplier with the control value corresponding to a luminance level of the visible region.

A stereoscopic image capture device includes a first image sensor, a second image sensor, a first frame timer, and a second frame timer. The first and second frame timers are different frame timers. The first image sensor includes a first plurality of rows of pixels. The second image sensor includes a second plurality of rows of pixels. The first and second image sensors can be separate devices or different areas of a sensor region in an integrated circuit. The first frame timer is coupled to the first image sensor to provide image capture timing signals to the first image sensor. The second frame timer coupled to the second image sensor to provide image capture timing signals to the second image sensor.

Systems and techniques are described herein for capturing images. For instance, a process can include obtaining a first image associated with a first exposure setting and obtaining a second image associated with a second exposure setting that is different from the first exposure setting. The process can include obtaining motion information associated with at least one of the first image and the second image and determining, based on the motion information, that motion associated with a first pixel of the first image exceeds a threshold. The process can include generating, based on the motion information, a fused image including a first set of pixels from the first image and a second set of pixels from the second image. The first set of pixels from the first image includes the first pixel based on the determination that the motion associated with the first pixel exceeds the threshold.
