摘要： Aspects of the present disclosure involve a system for capturing infrared (IR) images using an RGB camera. The system captures, by a camera of a client device, a first image comprising a visible light representing a real-world environment. The system receives a strobe signal for capturing an infrared (IR) image by the camera. In response to receiving the strobe signal, the system switches a filter associated with a lens of the camera to pass IR light to an image sensor of the camera, captures a second image comprising IR illumination of the real-world environment, and switches the filter after the second image is captured to allow visible light to pass through to the image sensor of the camera.

摘要： In various embodiments a computer-implemented method comprises generating, for a current video frame, a set of face motion data indicating whether a set of one or more faces detected in the current video frame has moved since a preceding video frame, generating a set of device motion data associated with one or more movements of an image capture device when capturing the current video frame, and generating a set of global motion data based on the set of face motion data and the set of device motion data, where the set of global motion data identifies a unique face motion when the set of face motion data indicates at least one face in the set of one or more faces has moved, and the set of device motion data indicates less than a threshold amount of motion of the image capture device when capturing the current video frame.

摘要： Tone mapping for image capture may include accessing a first image detected using an image sensor; accessing an exposure parameter (exposure duration, or time, multiplied by ISO or gain) used to detect the first image; scaling pixel values of the first image by a scale factor inversely proportional to the exposure parameter to obtain a scaled image; determining a scene luminance based on an average of pixel values of the scaled image; determining a target luminance based on the scene luminance; determining a target histogram based on the target luminance; determining a first histogram of luminance values of the first image; determining a transfer function based on the first histogram and the target histogram; applying the transfer function to pixel values of the first image to produce a tone mapped image; and storing or transmitting an output image based on the tone mapped image.

摘要： To reduce increased consumption of the recording capacity of a recording medium to record generated image data, an imaging device includes an imaging element and an image processor that receive subject light through an opening in a housing and generate image data, a recording controller that records the image data generated by the imaging processor onto a memory card, a lens cover movable to a position at which the lens cover covers the opening to restrict the subject light from entering the imaging element, and a determiner that detects a position of the lens cover based on the image data generated by the imaging processor and determines whether the lens cover covers the opening. The recording controller stops recording the image data onto the memory card when the determiner determines that the lens cover covers the opening.

摘要： To satisfactorily detect an edge detection signal of a high frequency band from a captured image signal at all times.
A filtering unit extracts an edge detection signal of a high frequency band from an image signal obtained from imaging, and a band control unit controls the high frequency band on the basis of lens information. For example, the filtering unit includes a first high-pass filter with a first cutoff frequency, a second high-pass filter with a second cutoff frequency that is lower than the first cutoff frequency, and an α blending unit that performs α blending on output of the first high-pass filter and output of the second high-pass filter. Even if the frequency of the edge detection signal included in the captured image signal varies due to a change in a zoom position, a lens model number, an F value or the like, the edge detection signal can be satisfactorily detected at all times.-

摘要： Systems and methods for controlling camera settings of a camera to improve detection of faces in an uncontrolled environment are described. A first image is received from the camera, where the first image is captured by the camera at a first set of camera settings. A face is detected in the first image. The camera is adjusted to a second set of camera settings based on the detected face, where the second set of camera settings different from the first set of camera settings. A second image is received from the camera, where the second image is captured by the camera at the second set of camera settings. The face is detected in the second image. A quality metric of the face in the second image is determined where the quality metric is indicative of an image quality of the face in the second image. The camera is adjusted to a new set of camera settings to increase the quality metric of the face in subsequent images, the new set of camera settings different from both the first set of camera settings and the second set of camera settings. Once a sufficient quality metric of the face is achieved, the face is acquired, or otherwise captured, by the camera or other sensors.
