Digital imaging system and method in which user operation of a digital zoom selection switch to increase digital zoom of a portion of an evaluation image is interrupted for at least an interval of time as a warning to the user that the digital zoom selection has reached a digital zoom ratio that corresponds to a predetermined minimum image resolution quality level in an image of a given size to be rendered from the portion of the evaluation image. The user can then resume increasing digital zoom selection only by opening and re-closing the zoom selection switch. A graphical indicator is used to show changes in zoom settings and the appearance of the indicator is changed when one or more predetermined digital zoom settings are reached to reinforce the visual warning to the user.

The invention discloses a method for taking photos through different field angle cameras and a terminal to acquire high-quality photos. The method comprises the steps that the imaging amplifying multiple required by a user at present is judged, one camera in the different field angle cameras is started to carry out shooting according to the relation between the imaging amplifying multiple required by the user at present and the multiple threshold, and the taken photos are output after digital zoom is carried out. According to the method, one camera in the different field angle cameras is started to carry out shooting according to the relation between the imaging amplifying multiple required by the user at present and the multiple threshold, and then digital zoom is carried out on the taken photos. Due to the fact that the field angles of the cameras are different and the obtained photos are different in definition, when the different field angle cameras are selected to take photos according to the difference of the photo amplifying multiple of the user, the photos are good in photo quality, and the high-quality photos can be obtained.

A digital zoom rate of two-dimensional images zoomed by a digital zoom unit is obtained. When the obtained digital zoom rate is larger than 100%, at least one of the digitally zoomed two-dimensional images is modified based on an enlarged amount of parallax to provide an amount of parallax between the digitally zoomed two-dimensional images equal to the enlarged amount of parallax. The enlarged amount of parallax is obtained by enlarging, at a moderated digital zoom rate, an amount of parallax between the two-dimensional images before being digitally zoomed, and the moderated digital zoom rate is obtained by moderating the digital zoom rate at a moderation rate, where the moderation rate increases as the zoom rate increases. Then, a display unit is caused to carry out three-dimensional display based on the modified two-dimensional images.

The invention relates to an image processing system, containing an optical digital camera (1) having means (4) that produce information representative of a specified geometric distance within the image using laser light in the detection range of the optical digital camera (1), said information representative of the specified geometric distance being processed together with the image information. Separating means (8) are arranged downstream of the digital camera, said separating means separating the information representative of the specified geometric distance from the image information. Subsequent evaluating means produce a distance value therefrom. Image storage means (9) additionally arranged downstream of the separating means are used to store the recorded image information. Adjustment means (14) automatically change the image size on a display in the form of a digital zoom for the purpose of setting the reproduction size according to a specified scale factor in such a way that an object contained in the image content, the physical dimension of which object corresponds to the specified geometric distance, is reproduced in a corresponding dimension that is multiplied by the specified scale factor.

An image capturing device and a digital zooming method thereof are proposed in the invention. The method includes the following steps. A scene is captured by a primary lens and a secondary lens to generate a primary image and a secondary image. Image rectification is then performed on the primary and the secondary images to obtain two corresponding rectified images. Feature points detected and matched from the two rectified images are used to determine a corresponding overlapping region, respectively. Pixel displacement and depth map in the two overlapping regions could be calculated and estimated. Image zooming and warping techniques are performed on the two rectified images to obtain corresponding warped images using a recalculated homography matrix according to each specific zooming factor. Finally, the two overlapping regions in the warped image are fused by a weighted blending approach to generate a digital zoomed image.

A camera with a pair of lens/sensor combinations, the two lenses having different focal lengths, so that the image from one of the combinations has a field of view approximately two to three times greater than the image from the other combination. As a user of the camera requests a given amount of zoom, the zoomed image provided will come from the lens/sensor combination having the field of view that is next larger than the requested field of view. Thus, if the requested field of view is less than the smaller field of view combination, the zoomed image will be created from the image captured by that combination, using cropping and interpolation if necessary. Similarly, if the requested field of view is greater than the smaller field of view combination, the zoomed image will be created from the image captured by the other combination, using cropping and interpolation if necessary.
