Digital imaging as a detector for generic analytical measurements

Abstract: Digital imaging was investigated as a potential means of processing high density dot arrays for analytical purposes. Using a high resolution digital camera, a colour image of the dot array was taken and subsequently processed using in-house developed National Instruments LabVIEW® software to return numerical values for the red, green and blue components of the colour of each dot.

Method and system for creating a temporary group of images on a digital camera

Abstract: A method and system for grouping a series of images stored in a digital camera. The digital camera includes a view finder for displaying a plurality of the image cells, where each of the image cells corresponds to one of the stored images. The digital camera also includes a navigation control button for positioning a highlight area around one of the plurality of image cells, and one or more function keys. The method and system includes assigning a mark function to one of the function keys, such that in response to the user pressing the assigned mark function key, the image cell currently highlighted is marked to provide a marked image. In response to the user repeating the above step, a group of marked images is created. The method and system further includes assigning at least one group function to one of the function keys, such that in response to a user pressing the assigned group function key, the group of marked images is collectively manipulated by the user.

Toward Real-World Single Image Super-Resolution: A New Benchmark and A New Model

Abstract: Most of the existing learning-based single image superresolution (SISR) methods are trained and evaluated on simulated datasets, where the low-resolution (LR) images are generated by applying a simple and uniform degradation (i.e., bicubic downsampling) to their high-resolution (HR) counterparts. However, the degradations in real-world LR images are far more complicated. As a consequence, the SISR models trained on simulated data become less effective when applied to practical scenarios. In this paper, we build a real-world super-resolution (RealSR) dataset where paired LR-HR images on the same scene are captured by adjusting the focal length of a digital camera. An image registration algorithm is developed to progressively align the image pairs at different resolutions. Considering that the degradation kernels are naturally non-uniform in our dataset, we present a Laplacian pyramid based kernel prediction network (LP-KPN), which efficiently learns per-pixel kernels to recover the HR image. Our extensive experiments demonstrate that SISR models trained on our RealSR dataset deliver better visual quality with sharper edges and finer textures on real-world scenes than those trained on simulated datasets. Though our RealSR dataset is built by using only two cameras (Canon 5D3 and Nikon D810), the trained model generalizes well to other camera devices such as Sony a7II and mobile phones.

Two dimensional/three dimensional digital information acquisition and display device

Abstract: A two dimensional/three dimensional (2D/3D) digital acquisition and display device for enabling users to capture 3D information using a single device. In an embodiment, the device has a single movable lens with a sensor. In another embodiment, the device has a single lens with a beam splitter and multiple sensors. In another embodiment, the device has multiple lenses and multiple sensors. In yet another embodiment, the device is a standard digital camera with additional 3D software. In some embodiments, 3D information is generated from 2D information using a depth map generated from the 2D information. In some embodiments, 3D information is acquired directly using the hardware configuration of the camera. The 3D information is then able to be displayed on the device, sent to another device to be displayed or printed.

Digital camera system and method capable of performing document scans

Abstract: A digital camera system is provided for capturing pictures of scenery or scanning the text of a document. A lens of the digital camera system receives light from a scene, and a conversion device defines a first set of digital data based on this light. A scanning mechanism included within the digital camera system scans a document as the system is passed over the surface of the document and produces a second set of data that defines an image of the document. An audio signal interface included within the digital camera system receives an audio message and defines a third set of digital data based on the audio message. A system controller stores the first, second, and third sets of data into a storage device. If desired, the first and second sets of data may be merged together to define a combined image depicting at least a portion of the scene defined by the first set of digital data and depicting at least a portion of the document defined by the second set of digital data.
