Claim:
An image-pickup apparatus comprising: a focus detecting part that detects focus information indicating a focus state of an image-pickup optical system; a color measuring part that detects color measurement information related to a color of an object; a controlling part that generates controlling information used in focus control using the focus information and the color measurement information; and a memory that stores the color measurement information, wherein, when the color measurement information stored in the memory is referred to as a first color measurement information, and color measurement information which is detected by the color measuring part after the first color measurement information is detected is referred to as a second color measurement information, the controlling part performs a determination related to a delay in the acquisition of the second color measurement information relative to the acquisition of the focus information, and, based on the determination result, switches the color measurement information used in generating the controlling information between the first color measurement information and the second color measurement information.
