1. An imaging apparatus comprising: an optical finder to be supplied with an optical image of an object;a display configured to display image information as an electronic image;an optical path combining unit configured to optically combine the optical image supplied to the optical finder and the electronic image displayed by the display with each other in an optical path of the optical finder; andat least one processor or circuit configured to perform the operations of units comprising an image display processing unit configured to perform image display processing to the image information,wherein the optical path combining unit includes an optical element which has first transmissivity in a first wavelength range of a visible light wavelength range, and has second transmissivity lower than the first transmissivity in a second wavelength range on a longer wavelength side than the first wavelength range, andwherein, when the optical finder is not supplied with the optical image of the object, the image display processing unit reduces an intensity of a color of the second wavelength range to be lower than a first predetermined value and increases an intensity of a color of the first wavelength range to be higher than a second predetermined value, in regard to the electronic image. 2. The imaging apparatus according to claim 1, wherein, when the optical finder is not supplied with the optical image of the object, the image display processing unit reduces an intensity of a red color of the second wavelength range to be lower than the first predetermined value and increases an intensity of a blue color of the first wavelength range to be higher than the second predetermined value, in regard to the electronic image. 3. The imaging apparatus according to claim 1, wherein, when the optical finder is supplied with the optical image of the object, the image display processing unit does not change the intensities of the respective colors of the first and second wavelength ranges in regard to the electronic image. 4. A method of controlling an imaging apparatus which comprises (1) an optical finder, (2) a display, (3) an optical path combining unit, and (4) an image display processing unit, the method comprising: supplying an optical image of an object to the optical finder;displaying, by the display, image information as an electronic image;optically combining, by the optical path combining unit, the optical image supplied to the optical finder and the electronic image displayed by the display with each other in an optical path of the optical finder; andperforming, by the image display processing unit, image display processing to the image information,wherein an optical element is provided to serve as the optical path combining unit, has first transmissivity in a first wavelength range of a visible light wavelength range, and has second transmissivity lower than the first transmissivity in a second wavelength range on a longer wavelength side than the first wavelength range, andwherein, when the optical finder is not supplied with the optical image of the object, an intensity of a color of the second wavelength range is reduced by the image display processing unit to be lower than a first predetermined value and an intensity of a color of the first wavelength range is increased by the image display processing unit to be higher than a second predetermined value, in regard to the electronic image.
