Remote-controlled camera-picture broadcast system

A remote-controlled camera-picture broadcast system is provided, which decreases the cost of hardware and network for the use of a lot of unspecified users. This system is comprised of a camera apparatus, a camera controller, a camera server connected to the camera controller through a first network, and clients connected to the camera server through a second network. Each of the clients transmits an operation demand for the camera apparatus to the camera server through the second network according to an input of a user. The camera server receives the operation demand from the client into which the input of the user is applied, and transmits an operation command corresponding to the operation demand to the camera controller through the first network. The camera controller controls the camera apparatus according to the operation command from the camera server so that the camera apparatus acquires a picture and produces a video signal of the picture. The camera controller receives the video signal of the picture produced by the camera apparatus, converts the video signal to a picture data, and transmits the picture data to the camera server through the first network. The camera server transmits the picture data through the second network to the client from which the operation demand has been transmitted, thereby displaying the picture of the picture data on a screen.

Linkable digital cameras for an image capture system

A system of linked digital cameras for an image capture system is disclosed. A first and second digital camera can be linked to capture a first images and a second image that are used to form a stereo image. A first data port on the first digital camera and a second data port on the second digital camera intercommunicate data between each other when the cameras are linked. The data can include the first and second image data, camera control data, and camera synchronization data. After capturing the first and second images, the image from one of the cameras can be transferred to the other camera so that both the first and second images reside in the other camera. The system allows a user who wishes to capture stereo images the ability to do so with out having to purchase two digital cameras. A compatible digital camera can be borrowed from another user for the purpose of stereo image capture. After the stereo image is captured, the user transfers both images to his camera and returns the borrowed camera. The cameras can be equipped with viewfinders that allow a user of the cameras to view the image being captured in stereo. The viewfinders can be adjustable to accommodate variations in user interpupillary distance. A digital camera operating system (OS) can be customized to enable stereo image capture, image data handling, image processing, and camera control for the linked digital cameras.

Handheld imaging device employing planar light illumination and linear imaging with image-based velocity detection and aspect ratio compensation

A hand-held imaging device includes a plurality of linear imaging arrays, image formation optics, at least one illumination module and image processing circuitry that are embodied within a hand-holdable housing that is moved by hand movement past a target object to capture images of the target object. The plurality of linear imaging arrays and image formation optics provide field of views corresponding to the plurality of linear image arrays. The at least one illumination module produces planar light illumination that substantially overlaps the field of views corresponding to the plurality of linear imaging arrays. The image processing circuitry performs image-based velocity estimation operations, which analyzes pixel data values of a plurality of composite 2D images each derived from sequential image capture operations of a corresponding one linear imaging array to derive velocity data that represents an estimated velocity of the imaging device with respect to target object. The image processing circuitry produces a first image of portions of the target object, the first image having substantially constant aspect ratio, utilizing image transformation operations (or camera control operations) that are based upon the velocity data, to thereby compensate for aspect ratio distortions that would otherwise result from variations in velocity of the imaging device with respect to the target object(s). In addition, the image processing circuitry preferably carries out image-based horizontal jitter estimation and compensation operations, which estimate the horizontal jitter of the imaging device relative to the target object over the image capture operations from which the first image is derived, and transform the first image utilizing shift operations that are based upon such estimated horizontal jitter to produce a second image of portions of the target object which compensates for horizontal jitter distortion that would otherwise result therefrom. The first image, second image (or image derived from sharpening the first or second images) is preferably subject to image-based bar code detection operations and/or OCR operations carried out by the image processing circuitry, or output for display to a display device.

Embedded imaging and control system

A stand alone imaging system is disclosed that captures undistorted, high resolution, stop-action images of objects (e.g., medicine pills) moving at automation speeds, processes the images in real time, and then performs real-time I/O based control that is a function of the image processing results. The imaging system has a form factor that enables it to be embedded inside a product (e.g., a pill dispenser). The imaging system also has a flexible I/O system so that a variety of different applications can be handled by changing only the programming and the external hardware connected to the device in which the imaging system is embedded. In the case of pill dispensing and quality control, a miniature, low cost imaging system can be embedded in a pill dispenser to obtain a pill image and then process the image in real time as the pill moves through a counting system. The embedded imaging system processes the images fast enough and with sufficient quality and resolution so as to command a pill counting mechanism to dispense or reject the pill based on the image processing results. Images of the pills can also be sent to a remote location or an archive. The embedded imaging system has sufficient processing power and I/O to control the entire pill counting mechanism. Lighting may be provided by a separate solid state lighting source which may be controlled by the embedded imaging system's camera or operated independently. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
