Problems solved by technology

[0012] The flash can also be used as a means of solving the problem in the case of still images, but it cannot be used for video
In addition, some digital cameras, especially mobile terminals equipped with digital cameras, do not have a flash light at all due to space / price / energy consumption considerations

Abstract

The present invention relates to an electronic equipment (10) for imaging which includes the following component: a camera device (CAM) which uses the preset exposure parameter (ET, AG, DG) to form the picture frame (FRp, FRc), a device (11) which confirms the total exposure amount (EV) according to at least some picture frames, and an exposure parameter adjusting device (12) which adjusts the exposure parameter basing on the confirmed exposed total exposure amount. Otherwise, the equipment (10) also includes a motion detecting device (13) for detecting movement from at least some picture frames. In the equipment the exposure parameter is collocated that the exposure parameter is adjusted according to the exposed total exposure amount and the detected movement.

Description

technical field [0001] The invention relates to electronic equipment for performing imaging, comprising: [0002] - a camera device forming an image frame using the set exposure parameters, [0003] - means for determining a total exposure to determine a total exposure of exposures from at least some of said image frames, and [0004] - Exposure parameter adjustment means for adjusting said exposure parameters based on said determined total exposure of exposures. [0005] In addition, the present invention also relates to corresponding methods, systems and program products. Background technique [0006] When achieving still or video imaging of moving objects, for example, in low-light situations (for example, when taking indoor photos of children), images are often distorted due to motion and blur caused by long exposure times. Figure 8d shows an example of a capture according to the prior art, where a stationary object is imaged by moving the camera vertically. [0007]...
