Abstract: A facial structure estimating device 10 includes an acquiring unit 11 and a controller 13. The acquiring unit 11 acquires a facial image. The controller 13 functions as an identifier 15, an estimator 16, and an evaluator 17. The identifier 15 identifies an individual based on a facial image. The estimator 16 estimates a facial structure based on the facial image. The evaluator 17 calculates a validity of the facial structure estimated by the estimator 16. The evaluator 17 allows facial images and facial structures whose validity is greater than or equal to a threshold to be applied to training of the estimator 16. The controller 13 causes application of facial images and facial structures whose validity is greater than or equal to a threshold to training of the estimator 16 to be based on identification results of individuals produced by the identifier 15.

Abstract: A printing apparatus includes a printer with printing elements that print dots and a controller that controls the printer on the basis of input image data. The controller acquires a pre-correction printing density that is based on test pattern data, which includes a uniform array of pixels, and printing characteristics of a dot size of the printing elements. The controller calculates a target density by averaging the pre-correction printing density and offsets the target density so that the target density is equal to or greater than the pre-correction printing density. The controller calculates a correction gain of the printing elements on the basis of the ratio of the target density to the pre-correction printing density and controls the printer on the basis of the correction gain and the input image data.
