Adjustment for output image of image data

Abstract

If a memory card is inserted in a slot, a control circuit of a color printer acquires image output control information from the memory card and analyzes this information. A CPU modifies a brightness standard value Bstd corresponding to a brightness parameter by taking account of a preset exposure bias value when an exposure bias value other than zero is set. The CPU determines the brightness correction level Brev by correcting the brightness representative value Brep so as to bring it closer to the brightness standard value Bstd that has been modified, and adjusts the image quality of image data by taking account of the brightness correction level Brev. As a result, the image quality of image data can be automatically adjusted without degrading output conditions that have been set arbitrarily.

1 . An image data generation device for generating image data that has been associated with image processing conditions for image data in an output device, said image data generation device comprising:
 an image data generator that generates image data;   an exposure bias value information acquirer that acquires exposure bias value information;   an image quality parameter value acquirer that analyzes said generated image data so as to acquire a value of an image quality parameter indicating at least a characteristic relating to a brightness of said image data;   an image processing conditions generator that generates said image processing conditions based on a standard image quality parameter value that is determined in advance for said image quality parameter value relating to said brightness, said acquired image quality parameter value, and said exposure bias value information; and   an output that outputs said generated image processing conditions and said image data associated with each other.   
     
     
         2 . An image data generation device according to  claim 1 , wherein
 said image processing conditions generator generates said image processing conditions so as to reduce or eliminate deviations in said image quality parameter value from said standard image quality parameter value by taking account of said exposure bias value information.   
     
     
         3 . An image data generation device according to  claim 1 , wherein said image processing conditions generator generates said image processing conditions by computing the image quality adjustment quantity from said standard image quality parameter value and said image quality parameter value, modifying said image quality adjustment quantity by taking account of said exposure bias value information, and using said image quality adjustment quantity that has been modified. 
     
     
         4 . An image data generation device according to  claim 1 , which further comprises a standard image quality parameter value modifier for modifying said standard image quality parameter value based on said exposure bias value information, and wherein
 said image processing conditions generator generates said image processing conditions based on said modified standard image quality parameter value and said acquired image quality parameter value, instead of said standard image quality parameter value, said acquired image quality parameter value, and said exposure bias value information.   
     
     
         5 . An image data generation device according to  claim 4 , wherein
 said standard image quality parameter value modifier does not conduct modification of said standard image quality parameter value when said acquired exposure bias value is zero.   
     
     
         6 . An image data generation device according to  claim 1 , wherein said image data are output after having been stored in the same file as said image processing conditions. 
     
     
         7 . An image data generation device according to  claim 2 , wherein said image data are output after having been stored in the same file as said image processing conditions. 
     
     
         8 . An image data generation device according to  claim 3 , wherein said image data are output after having been stored in the same file as said image processing conditions. 
     
     
         9 . An image data generation device according to  claim 4 , wherein said image data are output after having been stored in the same file as said image processing conditions. 
     
     
         10 . An image data generation device according to  claim 5 , wherein said image data are output after having been stored in the same file as said image processing conditions.
