However, if the point where the user intends to set an appropriate exposure value corresponds not to the trees TR1 and TR2 but to the house HO, then as Figure 14C As shown, the exposure value had to be corrected to set the proper exposure value for the house HO, and the image had to be taken again

[0026] figure 1 is a schematic diagram showing the configuration of the imaging system 1 according to the embodiment of the present invention. The imaging system 1 includes an imaging device 100 , and a lens 200 and a flash device (light emitting device) 300 mounted on the imaging device 100 .

[0027] The imaging apparatus 100 includes a main controller 101, an image sensor 102, a shutter 103, a main mirror 104, a focus plate 105, a detector 106, a focus detector 107, a gain setting unit 108, an A / D converter 109, and a timing generator (TG )110. Furthermore, the imaging apparatus 100 includes an image processor 111 , an operation unit 112 , a display unit 113 , a pentaprism 114 , and a sub mirror 115 .

[0028] The main controller 101 controls the overall operation of the imaging apparatus 100 (ie, each unit of the imaging apparatus 100 ). The main controller 101 is constituted by, for example, a one-chip IC circuit having a built-in microcomputer, wherein the one-chip I...

[0113] In the first embodiment, the flash device 300 selects an area to be set to have an appropriate luminance value among a plurality of areas obtained by dividing the imaging area of ​​the image sensor 102 . However, the imaging apparatus 100 may select an area to be set to have an appropriate luminance value among a plurality of areas obtained by dividing the imaging area of ​​the image sensor 102 .

[0114] Figure 8 is a flowchart for explaining the FEL operation when the imaging apparatus 100 selects an area to be set to have an appropriate luminance value among a plurality of areas obtained by dividing the imaging area of ​​the image sensor 102 . Note that steps S802-S810, S816, and S818 are the same as steps S402-S410, S420, and S422, and descriptions of these steps are not repeated.

[0115] In step S812 , the main controller 101 displays on the display unit 113 the difference between the luminance values ​​on each of the plurality of areas obtained by dividing the ...

[0123] In the first embodiment, after the FEL processing, the strobe device 300 selects an area to be set to have an appropriate luminance value among a plurality of areas obtained by dividing the imaging area of ​​the image sensor 102 . However, in the flash device 300, a plurality of areas obtained by dividing the imaging area of ​​the image sensor 102 can be displayed on the display unit 318, and the input unit 317 can be used to set (select) in advance the area to be set to have an appropriate brightness value. area, and the set area can be set to have an appropriate brightness value.

[0124] In this way, in the strobe device 300, an area to be set to have an appropriate luminance value can be set in advance among a plurality of areas obtained by dividing the imaging area of ​​the image sensor 102, and preliminary lighting can be performed to calculate the actual image pickup time of the strobe device 300. of luminescence. Even in a composition including a plurality of s...

Abstract

The present invention concerns an image capturing apparatus, a light-emitting device and an image capturing system. The image capturing apparatus, which is configured to capture an image using a light-emitting device, includes a photometry unit configured to perform photometry on a plurality of regions, a calculation unit configured to calculate an emission amount of the light-emitting device based on photometry results of the photometry unit, and a display unit configured to display information associated with differences between proper emission amounts respectively for the plurality of regions and the emission amount calculated by the calculation unit.

Description

technical field [0001] The present invention relates to an imaging device, a light emitting device and an imaging system. Background technique [0002] In an imaging device such as a digital camera, etc., there is known a technique of performing dimming control by setting a dimming area based on information (accessory information) of a lens and a flash mounted to the imaging device (see Japanese Patent Application Laid-Open 2007- 212866). [0003] However, even when the dimming area is set based on accessory information as in the related art, in a composition including a plurality of subjects, an appropriate exposure value cannot often be set for a point (area) desired by the user (photographer) (amount of light). The above-mentioned problem also occurs in the following cases: the flash is controlled to emit preliminary light, the light receiving unit of the camera receives the reflected light from the subject, and the light emission of the flash at the time of actual shoo...
