The example of the light emission amount for every color component for light color balance correction | amendment is shown.

  As shown in FIG. 1, the imaging device 1 has a horizontally long box-shaped casing 2, and a photographing lens storage unit 3 is arranged slightly left from the lower center when viewed from the front of the casing 2. A finder 4 is arranged in the upper right part. In addition, a light receiving unit 11 that detects ambient light is disposed slightly to the left of the center of the housing 2 and a light emitting unit 12 that emits illumination light is disposed to the right of the center.

  The imaging apparatus 1 also includes an ambient light color balance correction system 5 as shown in FIG. The ambient light color balance correction system 5 includes the light receiving unit 11, the light emitting unit 12, and the control unit 6 described above.

For example, three sensors for each color component may be combined, or one color sensor capable of detecting each of these three color components may be used, but is not limited thereto.

  The light emitting unit 12 can emit illumination light of a red component, a blue component, and a green component, respectively, and the light emission amount of each color can be independently controlled. For example, a red LED, a blue LED, and a green LED may be combined, or an RGB chip mounted chip LED in which these three-color chip LEDs are incorporated in one package may be used, but is not limited thereto. .

  The control unit 6 calculates the color balance of the ambient light based on the red, blue, and green components of the ambient light detected by the light receiving unit 11, and corrects the color balance to a color balance that allows natural shooting. Therefore, the light emission amount of each color of the light emitting unit 12 is determined, and the light emission of each color of the light emitting unit 12 is controlled based on the obtained light emission amount.

  For example, as shown in FIG. 3A, when the relative ratio for each light component of the ambient light detected by the light receiving unit 11 is 1.0 for the red component and 0.5 for both the blue and green components, It can be seen that the ambient light has a strong red component.
