[0029] figure 1 It is a block diagram showing the configuration of an example of the electronic imaging device according to the first embodiment of the present invention. figure 1 The example in is a single-lens reflex type digital still camera 301 constituted by a lens unit 100 and a camera body 200 which are detachably connected to each other.

[0030] A lens unit 100 serving as an optical lens is provided with an optical system 101 including a focus lens, a diaphragm, a zoom lens, etc., and focuses light from an unillustrated subject onto an imaging element 201 a in the camera body 200 . here, in figure 1 The illustration is omitted in , and each lens constituting the optical system 101 is driven by a not-shown lens driving mechanism, and the diaphragm is driven by an not-shown diaphragm driving mechanism.

[0031] Also, a microcomputer 102 and a flash memory 103 are provided in the lens unit 100 . The microcomputer 102 controls each part in the lens unit 100 according t...

[0075] Next, a second embodiment of the present invention will be described. Figure 8 It is a block diagram showing the configuration of an example of an electronic imaging device according to a second embodiment of the present invention. here, in Figure 8 in, endowed with figure 1 The structure of the same label as the figure 1 The same, so the description is omitted. exist Figure 8 The camera body 200 of the shown camera 301 is provided with an optical path branching prism 401 . The optical path branching prism 401 branches the light converged by the optical system 101 , makes one of the branched lights enter the camera module 402 , and makes the other light enter the camera module 403 . With such a configuration, the light from the subject can be incident on the two imaging modules at the same time.

[0076] The camera module 402 is a camera module for live view display, and is composed of an image sensor 402a, an I / F circuit 402b, and a flash memory 402c. In addi...

Abstract

An electronic imaging apparatus includes a color imaging device having several drive modes including at least first and second drive modes. A simultaneous shooting unit simultaneously or continuouslyexecutes an operation of acquiring a first image data by driving the color imaging device in the first drive mode and an operation of acquiring a second image data by driving the color imaging devicein the second drive mode. A color conversion parameter calculator calculates color conversion parameters so that color reproduction of the first and second image data acquired by the simultaneous shooting unit becomes the same.

Description

technical field [0001] The present invention relates to an electronic imaging device and an electronic imaging method using a color imaging element, and in particular to an electronic imaging device and an electronic imaging method that can use a color imaging element to perform still image photography and live view display. Background technique [0002] Among electronic imaging devices such as digital still cameras (hereinafter appropriately referred to as cameras), there are electronic imaging devices provided with a plurality of color imaging elements having different drive modes. For example, among digital still cameras, a digital still camera having a drive mode for still image shooting and a drive mode for live view display has been proposed. In the drive mode for still image shooting, all outputs of the imaging elements are read in order to give priority to the quality of still images to be recorded. On the other hand, in the so-called live view display drive mode in...
