• and
• a display control device that controls the display device so as to simultaneously display at display positions different from each other:
• (i) the recording image quality and the number of pixels of a recorded image changed through an operation of the setting change operation member, and (ii) the predetermined information represented either by a first style that uses only an indication on the display element or by a second style that combines indications on the display element and the auxiliary display element, and affected by a change of one of the recording image quality and the number of pixels of the recorded image, one of the first style and the second style being selected based upon the change.

An electronic camera comprising:

• a numeral display element that displays a numeral representing predetermined information;
• an auxiliary display element that displays a mark representing the predetermined information of a predetermined numeral;
• a decision making device that decides whether or not the numeral representing the predetermined information is equal to or greater than the predetermined number of digits;
• an arithmetic operation device that executes an arithmetic operation for a number of remaining frames by using the predetermined numeral if the decision making device decides that the numerical value information is equal to or greater than the predetermined numeral;
• and
• a display control device that implements control so as to, if the number of remaining frames is smaller than the predetermined number of digits, without the arithmetic operation executed by the arithmetic operation device, display a representation of the number itself of remaining frames by indication on only the numeral display element and no indication on the auxiliary display element, and so as to, if the number of remaining frames is equal to or greater than the predetermined number of digits, with the arithmetic operation executed by the arithmetic operation device, display the representation of the number itself of remaining frames by combining indications on the numeral display element and the auxiliary display element.

An image data processing device, comprising:

• a first display element that displays a numeral;
• a second display element that displays a single mark representing a predetermined number of digits;
• an arithmetic operation device that executes an arithmetic operation for numerical value information by using the predetermined number of digits if the numerical value information is equal to or greater than the predetermined number of digits;
• and
• a display control device that controls the first and second display elements so as to display one representation of numerical value information by using only the first display element without using the second display element when the arithmetic operation device executes no arithmetic operation, and by simultaneously using the first and second display elements when the arithmetic operation device executes the arithmetic operation;
• wherein
• the image data processing device is an electronic camera that records a shooting image on a recording medium,
• the first display element displays a three-digits numerical display,
• the second display element displays a mark showing a unit of 1,000 and
• the display control device displays a number of remaining frames of the recording medium by using only the first element when the number of remaining frames that can be recorded on the recording medium is equal to or smaller than 999, and the number of remaining frames is displayed by using the first and second display elements when the number of remaining frames is equal to or greater than 1,000.

An image data processing device, wherein the image data processing device is an electronic camera that records a captured image on a recording medium, comprising:

• a display device that can display numerical value information in a plurality of display forms different from each other, one display form of the plurality of the display forms including a display form that displays the numerical value information by using a single mark indicating a predetermined number of digits;
• and
• a display control device that selects a display form of one of the plurality of display forms according to the number of digits of the numerical value information and displays the numerical value information in the selected display form, wherein:
• the display device includes a first display element that displays three digits of a numeral display and a second display element that displays a mark showing a unit of 1,000, and
• the display control device displays the number of remaining frames of the recording medium by using only the first display element when the number of remaining frames that can be recorded on the recording medium is equal to or smaller than 999, and the number of remaining frames is displayed by using the first and second display elements when the number of remaining frames is equal to or greater than 1,000.

An image data processing device, comprising:

• a display device that displays numerical value information representing predetermined information;
• a decision making device that decides whether or not the numerical value information representing the predetermined information is equal to or greater than a predetermined number of digits;
• and
• an arithmetic operation device that simplifies the numerical value information by executing an arithmetic operation for the numerical value information by using the predetermined number of digits if the decision making device decides that a number of digits of the numerical value information is equal to or greater than the predetermined number of digits, and displays the simplified numerical value information on the display device, the simplified numerical value information including a display form that displays the numerical value information by using a single mark indicating the predetermined number of digits, wherein:
• the display device simplifies no numerical value information and displays the numerical value information by using no single mark on the display device if the decision making device decides that the number of digits of the numerical value information is smaller than the predetermined number of digits.

An image data processing device, comprising:

• a display device that includes a display element displaying a numeral and an auxiliary display element displaying a mark representing a predetermined number of digits;
• and
• a display control device that simultaneously executes a display showing a recording image quality and a number of pixels of a recorded image, and a display showing a numerical value that is represented either by a first style that uses only an indication on the display element or by a second style that combines indications on the display element and the auxiliary display element and is affected by a change of one of the recording image quality and the number of pixels of the recorded image at display positions different from each other in a state when a change of one of the recording image quality and the number of pixels of the recorded image currently set is allowed, one of the first style and the second style being selected based upon the change;
• wherein
• the display control device implements control so as to display setting elements including the recording image quality and the number of pixels of the recorded image, and to display the numerical value when the recording image quality and the number of pixels of the recorded image are not changed, and keeps displaying only the recording image quality, the number of pixels of the recorded image and the numerical value, when a change of one of the recording image quality and the number of pixels of the recorded image is allowed.
