Embodiment Construction

[0036]Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall block diagram showing a digital camera to which the display control device of the present invention is applied. It has an optical system 10 for capturing the image of the subject, an imaging element 11 composed of a CCD that converts the captured image of the subject into an electrical signal, that is, image data, an imaging circuit 12 that controls the imaging operation, and a camera for capturing the captured image. Image processing circuit 13 for performing image processing such as color correction and gamma correction on data, RAM 19 for temporarily storing captured image data, etc., ROM 20 for storing gain data described later, and color tone An interface (I / F) 21 that acts as a bridge between the ROM 18 of color palette data and OSD (On Screen Display) data, and a storage medium 22 such as a memory card that stores the captured image da...

Abstract

A display control apparatus displays image data expressed under a plurality of different color spaces. A discriminating section discriminates color space information on image data to be displayed. A gain switching section switches between gains in accordance with a result of the discrimination and sets a gain adapted for the image data to be displayed. An amplifying section amplifies an image signal, generated based on the image data and relating to at least a color difference, in accordance with the gain set by the gain switching section.

Description

technical field [0001] The present invention relates to a display control device and a display control method. Background technique [0002] Currently, various definitions are known in the RGB color space expressing colors. For example, in digital cameras, Exif (Exchangeable image format for digital cameras: Exchangeable image format for digital cameras) is stipulated as a standard specification for recording image file formats. RGB color space for sRGB. [0003] On the one hand, the current situation in the field of commercial printing is that a color space called Adobe (registered trademark) RGB having a color space wider than sRGB is mainly used as a substantially standard color space, and a color space suitable for different color spaces is also actively proposed. Other color spaces for use. Based on this situation, it is hoped that digital cameras can also use other color spaces than sRGB according to different purposes. [0004] However, when images based on RGB co...
