Electronic still video cameras of the type employing a solid-state imager device are known in the art, and examples are shown in U.S. Pat. Nos. 4,442,519, 4,446,265, 4,545,670, 4,550,484, 4,551,853, 4,555,621, 4,573,273 and 4,576,890. Typically, such cameras record and store image data on a two-dimensional array of picture elements (pixels) that form a video frame of the image. Each pixel is typically defined by a plurality of channels of data. In one such arrangement, the pixel is formed of a plurality of color-specific photodiodes arranged in a two-dimensional matrix for storing data corresponding to the amount of incident light of a selected color. For example, the pixel may comprise a matrix of photodiodes which each store a pair of color-specific photogenerated voltage signals for converting incident light of a first color into a first pair of voltage signals, and which further store a second pair of voltage signals corresponding to incident light of a second color. The stored first and second pairs of voltage signals are used to develop and store data corresponding to the image in the matrix of pixels. Such cameras are sometimes called "electronic film cameras", although they are capable of storing video image data directly on a solid-state imager device. The development of a video frame of data can be accomplished by sequential scanning of the frame, with the data stored in the imager array being read out of the imager and processed to produce a corresponding still image.
In many cases, it is desirable to optimize the color balance of the camera to provide pleasing image reproduction. This is often accomplished by setting the red, green and blue color gains or "gammas" at predefined optimum values. The green color gain is usually set at the largest value for the brightest image areas. The red and blue color gains are usually set at values which, in combination, achieve a pleasing color balance.
With the above prior art cameras, a problem has arisen in the setting of the color gains in that, for each color be359ba680
