no. 2 Embodiment approach

[0114] then use Figure 10 ~ Figure 22 A camera, which is an imaging device according to a second embodiment of the present invention, will be described below.

[0115] The basic configuration of the camera of this embodiment is completely the same as that of the above-mentioned first embodiment, and there are only a few differences in the processing sequence.

[0116] In the camera of the above-mentioned first embodiment, the reference exposure image is obtained by normal photometry and exposure setting means, and the image data of different exposures are obtained by an instruction issued by the user's touch operation, and the two images are added. (synthesis) processing to obtain HDR images.

[0117] On the other hand, the camera of this embodiment has the following three different functions.

[0118] (1) In addition to the standard exposure image, three (or more) images are obtained through multiple touch operations by the user, and the same addition (synthesis) process i...

Abstract

The invention provides a photographic device, which can easily realize an HDR (High Dynamic range) image in a photographic action. The photographic device is provided with: a camera shooting part (12) shooting an object; a display part (23) displaying an image of image data acquired by the camera shooting part; a touch panel (25) disposed on the display part and designating coordinates corresponding to an input operation; a control part (11) setting a designated region comprising coordinates in the image corresponding to the coordinates designated by the touch panel; an exposure control part (14) performing light measurement of shot object light and setting a proper exposure value according to the image data acquired by the camera shooting part, and generating an image based on the set proper exposure value; and an image processing part (15) performing image synthesis processing according to a plurality of image data acquired by the camera shooting part, wherein the exposure control part generates a reference image based on the proper exposure value set according to the image data and an image based on the proper exposure value set according to the image data in the designated region, and the image processing part performs synthesis processing of a plurality of images generated by the exposure control part.

Description

technical field [0001] The present invention relates to a photographic device, and more particularly to a photographic device capable of performing high dynamic range (HDR) image composition processing within the device. Background technique [0002] Conventionally, in imaging devices such as digital cameras to which imaging elements are applied, various types of image processing are performed on image data acquired through imaging operations, thereby obtaining images in various formats. Especially in recent years, due to the influence of the improvement of the processing speed of the image processing circuit, it is possible to check in advance the situation when various image processing is performed while performing the so-called live view display at the stage before shooting and recording. An image of the processing result. [0003] In addition, in photographing equipment in recent years, an operation member such as a touch panel is arranged on the display portion of a di...
