Abstract: Provided is an apparatus and method that enable capturing of an image according to a timing of image-capturing operation by making a release time lag constant. The apparatus includes an imaging element and a control unit that performs output control of a synchronization signal that defines processing timing of the imaging element, in which the control unit outputs a first additional synchronization signal to the imaging element at an end timing of exposure preparation processing started in response to image-capturing operation. The imaging element starts exposure processing of a captured image corresponding to the image-capturing operation in response to input of the first additional synchronization signal.

Abstract: The present disclosure relates to a beam forming device, comprising a transmit unit comprising at least two transmit elements that transmit radiation towards a scene, a receiver unit comprising at least two receive elements that receive radiation from said scene and that generate receive signals from said received radiation, and a beam forming unit that performs beam forming to obtain beam formed output signals from said receive signals by use of beam forming weights, wherein said beam forming weights are adapted to a distance between the scene and one or more transmit elements and/or receive elements, said distance being indicated by a distance indicator, and wherein said beam forming weights are changed if said distance changes.

Abstract: An image processing apparatus includes a generation unit for generating a plurality of different values for one parameter of a processing applied on an image, a presentation unit for presenting a plurality of processing images obtained by performing a processing on the image with the plurality of different values for the parameter, and a selection unit for selecting an optimal one of the plurality of presented processing images, in which a final value for the parameter is decided by repeatedly performing such a procedure that the generation unit further generates different values for the parameter on the basis of a value for the parameter corresponding to the selected processing image, the presentation unit presents processing images obtained by performing a processing on the image with the generated different values for the parameter, and the selection unit selects an optimal one of the presented processing images.
