摘要： A system and method for efficiently performing a depth map recovery procedure includes an imaging device that is implemented in a single-lens stereo-shutter configuration for simultaneously capturing overlaid images corresponding to a photographic target. A depth map generator is configured to analyze the overlaid images to determine disparity values corresponding to separation distances between matching points in the overlaid images. The depth map generator then utilizes the disparity values to calculate depth values that correspond to locations in the photographic target. The depth map generator may then utilize the foregoing depth values for creating a depth map corresponding to the photographic target.

摘要： A display panel image stabilization method and apparatus includes enabling a user to adjust both the pixel clock pulses and the synchronization for the display panel simultaneously by a single control. The synchronization is adjusted in a stepwise manner through a given number of steps for a particular number of clock pulses. The image is observed by the user to determine whether or not the noise stripes are being eliminated. The stepwise adjustment of the synchronization is repeated for another particular number of clock pulses if the noise stripes are not being eliminated. Once all of the stripes have been eliminated from the image, both the synchronization and the pixel clock pulses are properly adjusted to stabilize the image.

摘要： A two picture matching curve information is able to be used to determine precise object distance or relative object distance in a scene. Acquiring two images with different blur information in addition to the curve information enables a device to determine distance information of objects in a scene. The distance information is able to be used in image processing including generating a depth map which is then able to be used in many imaging applications.

摘要： Apparatus and method for electronically estimating focusing distance between a camera (still and/or video camera) and a subject. Images at different focal positions of a calibration target are collected with distances between subject positions. In one aspect, histogram matching is performed to reduce noise error. A focus matching model is then generated in response to detected blur differences between successive images of the calibration target. The focus matching model is preferably converted to a polynomial equation of a desired order to smooth out image collection noise. The focus matching model is stored for access during operation. In use, the distance to subject is estimated in response to capturing images, detecting blur differences between the images and entering the blur difference information into the matching model.
