摘要： PROBLEM TO BE SOLVED: To provide a generation system of a signal conversion table, a generation method of the signal conversion table, and a generation program of the signal conversion table for generating a signal conversion table for use in adjustment of picture quality so that tone of the picture quality approximates tone of target picture quality. SOLUTION: A control part of a picture quality adjusting device measures input/output characteristics of a reference video display device 20 and an adjustment target video display device 10. When a region (a reference output signal space) defined by a reference output signal value is not included in a region defined by a value of a signal to be adjusted, the control part sets a virtual input signal obtained by expanding the input signal and calculates a virtual output signal corresponding to the virtual input signal. When the reference output signal space is not included in a region (a virtual output signal space) defined by a value of the virtual output signal, the control part resets the virtual input signal until the reference output signal space is included. When the reference output signal space is included in the virtual output signal space, the control part calculates a tentative LUT, clips a space expanded in the tentative LUT to generates a LUT.

摘要： PROBLEM TO BE SOLVED: To provide an image processing apparatus, image processing method and image processing program in which image data are compressed less than or equal to fixed capacitance while reducing the effect of image quality deterioration and data transfer or recording can be performed. SOLUTION: A compression data generating means 12 of a compression data processing unit 10 performs conversion processing on differential data, calculates a differential value and uses the differential value and group discrimination data to perform assignment processing of a Huffman code in accordance with generation frequency of data in each group. In a case where an average code length of 1 line does not become shorter than or equal to a target value because of the Huffman code, the compression data generating means 12 iteratively performs budgeting and quantization and specifies an SX value with which the average code length becomes shorter than or equal to the target value. The compression data generating means 12 converts values of pixels using the SX value at the time when the average code length becomes shorter than or equal to the target value, the Huffman code and positive and negative codes imparted to the groups.
