Disclosed are a face image and iris image acquisition method and device, a computer-readable readable storage medium and an apparatus. The method includes rotating the first tripod head to force the face lens and the iris lens to be in acquisition positions; capturing a first face image and a first iris image simultaneously by the face lens and the iris lens; and locating the iris in the first iris image, and if no iris is located, determining whether a condition of light-avoiding rotation is satisfied, and if the condition is satisfied, rotating the second tripod head to adjust an angle or a position of the supplementary light source to enable a light spot region to avoid an iris region.

The image processing unit selects multiple subject areas from strobe-ON image data to be corrected, and, from the selected multiple subject areas, the image processing unit acquires a feature amount such as gloss information corresponding to each subject. Subsequently, from each subject area, the image processing unit selects a part of the subject area, based on the acquired feature amount. Then, regarding the partial area of each subject area, which is selected based on the feature amount, the image processing unit estimates the auxiliary light arrival rate corresponding to each subject, based on a pixel value of the strobe-ON image data and a pixel value of strobe-OFF image data. Thereafter, based on the estimated auxiliary light arrival rate, the image processing unit corrects the brightness of each subject area of the strobe-ON image data, in order to generate corrected image data.

An arrangement for determining an amount of light reaching an image sensor of a video camera is disclosed. The video camera comprises an imaging lens system guiding a beam path towards an image sensor and has an aperture plane where a variable aperture is arranged. The inventive arrangement comprises a light sensor arranged to probe light intensity continuously from a portion of the beam path, which portion is located in or near the aperture plane of the imaging lens system.

Methods, systems, and apparatus, including computer programs encoded on computer storage media relate to a handheld wireless endoscope image streaming apparatus. The apparatus may establish a wireless connection to a computer system. The apparatus may obtain, via a digital camera, video imagery via an endoscope, the video imagery including multiple frames. The apparatus may stream to a computer system video data.

An electronic device includes a UDC and a UDC controller configured to determine an optimal number of frames required to be captured for a scene to compensate at least one parameter to optimize an output media using the UDC, obtain a multi-frame fusion media by performing at least one multi-frame fusion on the determined optimal number of frames, perform a light source spread correction on the multi-frame fusion media, and optimize the output media based on the light source spread correction on the multi-frame fusion media.

The imaging apparatus includes: a processor; and an imaging element that has column signal lines, which are for reading out signals and extend in a first direction, and that has a first pixel group and a second pixel group arranged in the first direction, the first pixel group including phase difference pixels and imaging pixels arranged in a second direction intersecting the first direction and the second pixel group including imaging pixels arranged in the second direction. The processor is configured to set one of a first exposure time, during which the first pixel group is exposed, and a second exposure time, during which the second pixel group is exposed, shorter than the other, and determine which of the first exposure time and the second exposure time is made shorter than the other on the basis of information of a subject image.

The technical problem of enhancing the quality of an image captured by a front facing camera in low light conditions is addressed by displaying the viewfinder of a front facing camera with an illuminating border, termed a viewfinder ring flash. A viewfinder ring flash acts as a ring flash in low light conditions. A viewfinder ring flash may be automatically generated and presented in the camera view user interface (UI) when the digital sensor of a front facing camera detects a low light indication based on intensity of incident light detected by the digital image sensor of the camera.
