  • Patent number: 11006038
    Abstract: An image capture device obtains first image data from a front facing camera on a front face of the device including a display. The first image data represents a subject within a field of view of the image capture device. Facial recognition is performed in response to the first image data from the front facing camera. The front image data is used for determining whether any subject is a priority subject, of whom at least one priority subject image-indicative data is accessible by the image capture device. A region of interest is selected, corresponding to the subject determined to be a priority subject. Automatic focus, automatic exposure, or automatic white balance is performed using the selected region of interest. Second image data from the front facing camera are captured based on the automatic focus, automatic exposure, or automatic white balance using the selected region of interest.

  • Patent number: 10897558
    Abstract: This disclosure relates to the lightweight and efficient synthesis of shallow depth of field (SDOF) renderings. According to some embodiments, coarse focus information and semantic segmentation information may be leveraged to generate SDOF renderings in a “live preview” or “streaming” mode. Semantic segmentation may be defined as a process of creating a mask over an image, wherein pixels are segmented into a predefined set of semantic classes. Segmentations may include as many classes as are desired by a given implementation (e.g., a ‘foreground’ class and a ‘background’ class). In some embodiments, the rendering of synthetic SDOF images according to the techniques described herein may be completed using only a single camera of a device and without the use of dedicated depth-sensing technology (e.g., structured light cameras, stereo cameras, time-of-flight cameras, etc.), thereby allowing the SDOF rendering process to operate in a fashion that is not unduly time-, processing-, and/or power-intensive.

In a case where an observation target is imaged multiple times, a focusing position of an observation region within a culture vessel is detected by auto-focus control during first imaging, and the first imaging of each observation region is performed using the focusing position. Next, the focusing position of a reference position is detected by auto-focus control during second imaging subsequent to the first imaging, and the focusing position of each observation region detected in the first imaging is corrected on the basis of the detected focusing position and the focusing position of the reference position in the first imaging.

  • Patent number: 10757312
    Abstract: A method for image processing and a mobile terminal, and a computer readable medium are disclosed. In one method, n number of first images and m number of second images are acquired. The first images and the second images are captured by a primary camera and a secondary camera respectively, and both the n and the m are integers greater than 2. A synthesizing-denoising process is performed on the n number of first images and the m number of second images respectively to obtain a primary image and a secondary image respectively. Depth information of the primary image is obtained based on the primary image and the secondary image. A blurring process for the primary image is then performed based on the depth information of the primary image to obtain a target image.

  • Patent number: 10698182
    Abstract: The imaging lens consists of, in order from an object side: a first lens group that has a positive refractive power; a stop; a second lens group that has a refractive power; a third lens group that has a negative refractive power; and a fourth lens group that has a positive refractive power. The first lens group has, successively in order from a position closest to the object side, a negative meniscus lens that is convex toward the object side, a lens that is convex toward the object side, and a lens that is concave toward the object side. The third lens group consists of a negative lens. During focusing from an object at infinity to an object at a shortest distance, only the third lens group moves to an image side along an optical axis. The imaging lens satisfies a predetermined conditional expression relating to a focal length of the first lens group and a radius of curvature of an image side surface of a lens closest to the image side in the first lens group.
