Abstract: Ejection of ink is prohibited when a count value of an amount of ink supplied from an ink tank to an ejection head reaches a value limit. An image is displayed to prompt an operator of the printing apparatus to confirm the amount of ink in the ink tank. When the ink remains, the count value of the amount of ink is returned only by a given amount by the selection of the operator. Thus, since the ink in the ink tank is sufficiently consumed and then the ink can be supplemented, all of the ink in an ink bottle can be supplemented. As a consequence, it is possible to prevent the ink remaining in the ink bottle from deteriorating and prevent the remaining ink from being supplemented.

Abstract: In a radiation image capturing system, prior to radiation image capturing operation, the radiation image capturing apparatus repeats on an alternate basis, a step of reading leak data and a step of resetting each of the radiation detection elements, wherein the step of reading leak data is performed by turning off all switch units, allowing a reading circuit to perform cyclic reading operations under this condition and converting electric charge leaking out of radiation detection elements through the switch units into the leak data, thereby detecting a start of irradiation based on the leak data having been read out. The image processing apparatus analyzes a profile of image data along the extension of signal lines of the radiation image capturing apparatus, and identifies a range of the image data where a defect has occurred, whereby the image data in the identified range is corrected.

Abstract: If an ink amount supplied from an ink tank to an ejection head reaches a predetermined limit value, ink ejection is not permitted. If initialization data are input and the input initialization data are appropriate, a count value of the ink amount is initialized, and the ink ejection is started again. In addition, the initialization data which is input once and determined to be appropriate is determined to be inappropriate thereafter. By doing so, although ink of which the property and state are inappropriate is used for the refilling, since appropriate initialization data may not be input, it is possible to avoid the inappropriate ink from being used for the refilling.

Abstract: Provided is an apparatus capable of mounting an expendable cartridge thereon, including: a consumption amount counting unit that counts up the consumption amount of expendable cartridges in the apparatus when a change is detected for the first time during the continuous operation or the apparatus. The detected change is a residual expendable amount of the expendable cartridge decreasing from a value higher than a predetermined low residual level to a value lower than or equal to the low residual level. The consumption amount of the expendable cartridges is counted up and is detected in a number of different manners, depending on the circumstances surrounding the measured values of the residual expendable amounts and the replacement of the cartridges.

Abstract: A digital camera including a lens, first and second sensors, a shutoff member, a display, a detector, an exposure amount determiner, and a still image generator. The first sensor receives light through the lens and the second sensor also receives light through the lens, but is different from the first sensor. The shutoff member performs a first shutoff of the light received by the first sensor through the lens and also ends the first shutoff. The display displays a moving image based on the light received by the first sensor, and while the moving image is displayed, the detector detects a shutter operation. The exposure amount determiner determines, in response to the detected shutter operation, an exposure amount based on the light received by the second sensor when the first sensor does not receive light through the lens. The still image generator generates a still image based on the light received by the first sensor and the exposure amount determined by the exposure amount determiner.
