In a high speed image capturing state, a camera signal processing circuit is not needed to perform a signal process at a high screen rate, but at a regular screen rate. In the high speed image capturing mode, raw data of 240 fps received from an image sensorare recorded on a recording devicethrough a conversion processing sectionand a recording device controlling circuit. Raw data that have been decimated and size-converted are supplied to a camera signal processing circuitthrough a pre-processing circuitand an image being captured is displayed on a display sectionwith a signal for which a camera process has been performed. In a reproducing state, raw data are read from the recording deviceat a low screen rate according to a display performance of the display sectionand the raw data that have been read are processed are processed by the pre-processing circuitand the camera signal processing circuitand a reproduced image is displayed by the display section

An image processing apparatus, method and non-transitory computer program storage device cooperate to process successive images. Respective frames are created and positioned within the successive images, where each frame has a border. When changes between the frame borders are detected, a controller triggers the capturing of an image. This approach results in the capturing of interesting moments, even if the subject is not a human subject. The change in frame boundaries may be categorized in a variety of ways, including change in aspect ratio, shape, orientation, and position, for example. By detecting the changes in this way, an imaging device can capture images of interesting events automatically.

A method of improving accuracy and reliability of motion estimation is described herein. In one aspect, a 2D neighborhood of phase correlation peak is approximated with an outer-product of two 1D vectors to eliminate the sub-pixel error. In another aspect, estimation of reliability is improved. In yet another aspect, two-pass phase correlation is implemented to eliminate sub-pel motion bias.

Method to improve accuracy and reliability of motion estimated with phase correlation

The present invention relates to an image processing device and method, and a program whereby a subject can be imaged in a simpler manner with a desired imaging range. A size ratio calculating unitcalculates a size ratio between a region of interest that is a region of a subject of interest, and a partial region that is the region of a portion of the subject included in the region of interest with an imaged image that has been imaged, and a lens driving control unitcontrols the zoom power of an imaged image according to a zoom operation by a user so that the size ratio calculated by the size ratio calculating unit, and a predetermined value match or generally match. The present invention may be applied to an imaging apparatus.

Image processing device and method, and program

A method and system to improve the performance of phase correlation motion estimation for low-bit-precision implementation are described herein. Phase correlation uses the Fast Fourier Transform (FFT) with operations with infinite-precision constants. Since physical implementations use finite-precision arithmetic, there is some loss in precision relative to the ideal infinite-precision case. In low-complexity implementations, it is desirable to use as few bits as possible, and if the precision is too low, the performance of traditional phase correlation suffers. A pre-processing technique is applied to the data prior to taking the FFT, which minimizes the negative effects of finite precision in the FFT and allows high quality results from phase correlation. The pre-processing step is a content-dependent contrast adjustment that maps the range of the input images' pixel values to the range of input values for the FFT. There is no post-processing required after the FFT to compensate for the pre-processing step.
