    摘要： A color correcting circuit for thermal printer comprises a first circuit for obtaining a first degree correction operation result, a second circuit for obtaining a second degree correction operation result, and a difference limiting circuit for selectively outputting a correction data. The first degree correction operation makes the relationship between the density of an input image and the density of an output image linear for each primary color. The second degree correction operation reduces a difference between the density of the input image and the density of the output image by use of the method of least squares for each primary color. The difference limiting circuit selectively outputs as the correction data the second degree correction operation result when a difference between the first and second degree correction operation results falls within a predetermined range of a boundary value, and selectively outputs as the correction data a value which is deviated from the first degree correction operation result by the boundary value when the difference falls outside the predetermined range of the boundary value. The color correction of the input image is carried out based on the correction data outputted from the difference limiting circuit.

    摘要： A plurality of heat generating resistors (11a, 11b) arranged in line in a thermal head are driven such that two consecutive heat generating resistors (11a, 11b) are combined to cover a single picture element whose desired density is represented by each datum. A head drive circuit is provided so that only a first heat generating resistor (11a) is energized when the desired density is below a predetermined value, and that both the first and second heat generating resistors (11a, 11b) are energized when the desired density is equal to or above the predetermined value. The energizing duration of the second heat generating resistor (11b) is set to be within the energizing duration of the first heat generating resistor (11a) to reduce printing time, and the end of the energizing duration of the second heat generating resistor (11b) corresponds to the end of energizing duration of the first heat generating resistor (11a) so as to ensure linearity in tone value.
