摘要： The gamma curve generation method of the invention selects each set of three consecutive control points among multiple consecutive control points, forms a cubic curve passing through the selected three consecutive control points, and combines all formed cubic curves to generate a gamma curve. The selected three consecutive control points are set to a first control point, a second control point, and a third control point in a sequential order. Each cubic curve is formed to pass through the first control point, the second control point, and the third control point and have a tangent of a certain gradient at the second control point, which is internal division at an inverse ratio of a gradient of a straight line connecting the first control point with the second control point and a gradient of a straight line connecting the second control point with the third control point. This arrangement of the invention demands the less amount of computation and desirably reduces the required circuit scale.

摘要： There is provided a gamma curve adjustment device for use in a gamma correction circuit that performs gamma correction of an image signal, wherein the device is used to adjust the gamma curve indicating the relationship of input tone values to output tone values. The gamma curve adjustment device comprises a user interface module configured to permit a user to specify, desired output tone values for a plurality of pre-established adjustment points on the gamma curve; and an adjustment module configured to adjust the gamma curve such that the output tone value at each adjustment point assumes the value specified through the user interface module. The plurality of adjustment points are established such that a differential of input tone values between a first set of two adjustment points situated adjacently on the gamma curve differs from a differential of input tone values between a second set of two adjustment points situated adjacently on the gamma curve.
