  • Patent number: 11397417
    Abstract: A robotic system automatically aligns, and/or tests alignment of, a lens to a digital camera or other workpiece. The system includes an optical target, an intermediate lens and a plurality of collimators peripheral to the intermediate lens to accommodate a wide range of fields of view of the workpieces, without requiring changes in equipment hardware. When manufacturing or testing a workpiece with a relatively narrow field of view, the entire field of view of the workpiece can be filled with a view of the target through the intermediate lens, and the collimators need not be used. However, when manufacturing or testing a camera having a relatively large field of view, the intermediate lens is used to fill a central portion of the field of view with an image of the target, and the collimators are used to fill a remaining portion of the field of view with images of reticles.

  • Patent number: 11190744
    Abstract: An image processing device is described. The circuitry of the image processing device obtains an image that is generated on a basis of an incident light and a transfer function related to a conversion between the incident light and the image, and determines a cost function for prediction mode selection according to the transfer function. The cost function calculates a cost value based on a first parameter corresponding to a prediction residual code amount and a second parameter corresponding to a prediction mode code amount. The cost function is determined in a manner in favor of increasing the prediction residual code amount or decreasing the prediction mode code amount as a dynamic range of the transfer function increases. The circuitry determines a prediction mode for coding a coding unit of the image according to the determined cost function, and encodes the coding unit according to the determined prediction mode.

  • Patent number: 11190774
    Abstract: Techniques are described for efficiently encoding video data by skipping evaluation of certain encoding modes based on various evaluation criteria. In some solutions, intra-block evaluation is performed in a specific order during encoding, and depending on encoding cost calculations of potential intra-block encoding modes, evaluation of some of the potential modes can be skipped. In some solutions, some encoding modes can be skipped depending on whether blocks are simple (e.g., simple vertical, simple horizontal, or both) or non-simple. In some solutions, various criteria are applied to determine whether chroma-from-luma mode evaluation can be skipped. The various solutions can be used independently and/or in combination.
