Abstract

PURPOSE:To easily specify plural set modes by providing a means instructing the modification of a white balance set mode and a means modifying the setting in the prescribed sequence when the modification of the set mode is instructed. CONSTITUTION:Whenever a UP switch 16 is depressed with a WB switch depressed, the pattern displays of pictures PA2-PA10 are sequentially switched. For setting a white balance, the operation is set to the white balance corresponding to the display pattern after the prescribed time passes if the depression of the switch 12 stops at a stage where a desired pattern is displayed. If the white balance set on the picture PA8 is modified to that on the picture PA2, displays are sequentially switched whenever a DOWN switch 15 is depressed by pressing the switch 12. Consequently, if the depressions of the switches 12 and 15 stop when the picture PA2 is displayed, the current white balance is set to the one corresponding to the pattern of the picture PA.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to various cameras such as video cameras and electronic cameras that display a set white balance pattern.

[Prior Art] Generally, in a camera that performs white balance adjustment, a camera user rotates a volume for adjusting white balance, and sets a white balance mode according to the amount of rotation. This volume is designed to have scales, symbols, or letters indicating the level of white balance so that the camera user can know the amount of volume rotation. However, in conventional cameras of this type, the scale or symbol indicating the white balance mode is engraved on the volume or displayed with paint, etc., so it is difficult to use the camera for a long time or in a poor environment. However, there is the problem that the paint peels off, making it difficult to see the letters and symbols.Also, since there are many white balance setting modes, and therefore the number of indicator symbols increases, there is a problem that not all display mode symbols can be displayed. There were also points.
