の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a color printer adapted to print on a photographic paper from a negative film, and in particular, a color step and a density step are designated by a push button or a rotary switch. The present invention relates to an improvement of a color printer which prints and prints.

ステップの変化率は必然的に大きくなる。Generally, a color printer is provided with a push button or rotary switch, and by setting it, the color step that determines the exposure time of the B, G, and R color light and the density step that determines the overall exposure time are determined, and the negative film is printed on photographic paper. Is being printed on. Negative film has a wide range of negative densities for each frame taken due to differences in light exposure and the amount of exposure during shooting, while good for printed images on photographic printing paper. Color tone and density are required. Therefore, printing is performed by setting the above-mentioned color step and density step under various conditions. However, the number of color steps and density steps is limited in terms of operation, and on the other hand, the maximum rate of change is increased to cover variations in negative density.
The rate of change of steps will inevitably increase.
第２図(a)に従来のカラープリンタでの焼付条件設定用
のキーボードスイッチの１例を示す。B、G、R色光の補正
を行なうＢキー、Ｇキー、Ｒキーと、全体光の補正を行
なうＤキーよりなる。FIG. 2 (a) shows an example of a keyboard switch for setting a printing condition in a conventional color printer. It comprises a B key, a G key, and an R key for correcting B, G, and R color lights, and a D key for correcting the total light.
プリンタに設けた測光素子で焼付を行なうネガ部分の透
過光を側光し、LATD法により算出された露光時間に対し
何等補正を要しないときは、(B5、G5、R5、N)とステップキ
ーを押すことで補正がなされないでそのままの焼付がな
される。When the exposure light calculated by the LATD method does not need to be corrected by sidelighting the transmitted light of the negative part for printing with the photometric element provided in the printer, press (B5, G5, R5, N) and the step key. By pressing, the image is printed as it is without any correction.
隣り合うステップキー間での補正量の差異（１ステップ
の変化率）は前記の(B5、G5、R5、N)に対し右＋、左−と
し、一般に10％ないし15％に等比的あるいは等差的に設
定される。一般には等比的な変化率の設定（１ステップ
の変化率10％としたとき、B5＝±０％、B6＝＋10％、B7
＝＋21％、B8＝＋33％、B9＝＋46％）が多いが以下の例
示については等差的な変化率の設定（１ステップの変化
率10％としたとき、B5＝±０％、B6＝＋10％、B7＝＋20
％、B8＝＋30％、B9＝＋40％）について説明する。The difference in the correction amount between adjacent step keys (change rate of one step) is set to the right + and the left − with respect to the above (B5, G5, R5, N), and is generally proportional to 10% to 15% or It is set to be equal. Generally, setting of proportional change rate (when the change rate of 1 step is 10%, B5 = ± 0%, B6 = + 10%, B7
= + 21%, B8 = + 33%, B9 = + 46%), but in the following examples, setting the differential rate of change (when the rate of change in one step is 10%, B5 = ± 0%, B6 = ＋ 10%, B7 ＝ ＋ 20
%, B8 = + 30%, B9 = + 40%).
いま１ステップの補正量をB、G、R、D共に10％とした場
合、例えば第２図(b)に示すような(B5、G7、R3、Ｄ＋１）
の入力を行なうと（Ｂ＝±０％、Ｇ＝＋20％、Ｒ＝−20
％、Ｄ＝＋10％）の補正がなされた露光量で焼付がなさ
れる。If the correction amount for one step is 10% for each of B, G, R, and D, for example, as shown in FIG. 2B, (B5, G7, R3, D + 1)
Is input (B = ± 0%, G = + 20%, R = −20%)
%, D = + 10%), and printing is performed with the exposure amount corrected.
之に対して微調がなされた露光量の補正が行なえるカラ
ープリンタの要望もあり、このことを可能とするため、
別に10キーを設けて之によって微調補正を行なうように
したり、或いは特別なキーを設け、この特別なキーを作
動したときは＋1/2あるいは−1/2の変化率を加えること
がなされてきた。之等の方法は、操作性が極めて悪く微
調にまでは至らなかった。On the other hand, there is a demand for a color printer that can make fine adjustments to the exposure amount, and in order to make this possible,
Separately, 10 keys are provided for fine adjustment, or a special key is provided, and when this special key is operated, a change rate of +1/2 or -1/2 has been added. . These methods were extremely inferior in operability and did not lead to fine adjustment.
本発明は徒らにステップキーの数を増やすことなく、操
作性がよくて、露光量の微調補正を可能とするカラープ
リンタを提供しようとするものである。The present invention is intended to provide a color printer which has good operability and enables fine adjustment of the exposure amount without increasing the number of step keys.

プリンタにより達成される。The above-mentioned object is to provide a fine adjustment key on a color printer provided with a color step and a density step, and when the fine adjustment key is inoperative, the coarse printing condition with a change rate of the coarse adjustment is set by one input of the step. When the fine adjustment key is operated, the step is input twice, and in addition to the coarse printing condition having the change rate of the rough adjustment by the first input, the change rate of the fine adjustment by the second input is added. This is achieved by a color printer characterized in that fine adjustment with
本発明は新たに微調キーを１個だけ余分に設けたもの
で、キーボードは外形的には同じであるが、各ステップ
キーは粗調の変化率と微調の変化率の２段の変化率をも
たすようにしてある。In the present invention, only one extra fine adjustment key is newly provided, and although the keyboard has the same external shape, each step key has a two-step change rate of a coarse adjustment rate and a fine adjustment rate. I am trying to help.
そして特に微調を必要しないときは、微調キーを作動さ
せないことで、例えば第２図に示したような従来と同じ
粗調の変化率による露光補正で焼付がなされる。When fine adjustment is not particularly required, the fine adjustment key is not operated, so that printing is performed by exposure correction with the same coarse adjustment rate as in the conventional case as shown in FIG.

る。When fine adjustment is required, the fine adjustment key is first activated, which causes the keyboard to first enter the (I) mode with a coarse adjustment rate. Therefore, first, the exposure amount is corrected by the rough adjustment by the first operation. However, this is a tentative correction, and printing is not performed under this condition. When this provisional correction was completed, there was a change rate of fine adjustment in circuit or software (II)
Switch to mode. Therefore, in the fine adjustment correction by the second operation with the same keyboard, the fine adjustment with respect to the previous provisional correction is performed, and the corrected exposure amount subjected to the fine adjustment correction is determined accordingly.

%, D = + 10%) [(I) mode] For the above temporary correction, for example, 2 as shown in FIG. 1 (c).
When the (B5, G3, R9, D-1) is input a second time, (B = ± 0%, G = -4%, R = + 8%, D
= -2%) fine adjustment is performed, and [(II) mode] B = (± 0) + (± 0) = 0 G = (+ 20%) + (-4%) = 16% R = (-20 %) + (+ 8%) =-12% D = (+ 10%) + (-2%) = + 8% Printing is performed by the finely adjusted correction exposure described above.
