Abstract
An image processing apparatus is provided which is adapted to control image reading and recording operations in a balanced manner, thereby reducing power consumption includes image reading and recording portions; a power supply portion configured to supply power to the reading and recording portions in common; a detecting portion for detecting a recording density of image data to be recorded; and a controller configured to compare a detection result of the recording density with a predetermined threshold. Additionally, a control method and computer readable medium is provided for accomplishing the aforementioned in the apparatus.
Claims14
An image processing apparatus comprising:
- an image reading portion;
- an image recording portion;
- a power supply portion configured to supply power to the image reading portion and the image recording portion in common;
- a detecting portion configured to detect a recording density of image data to be recorded by the image recording portion;
- and
- a controller configured to compare a detection result of the recording density obtained by the detecting portion with a predetermined threshold, and control a recording,
- wherein when the detection result of the recording density is equal to or larger than the predetermined threshold, the controller causes the image recording portion to execute a processing of reducing recording power consumed by the image recording portion,
- wherein the predetermined threshold includes at least a first value and a second value smaller than the first value, and when no image reading is executed by the image reading portion during an image recording operation executed by the image recording portion, the controller compares the detection result with the first value, and
- wherein when image reading is concurrently executed by the image reading portion during the image recording operation executed by the image recording portion, the controller compares the detection result with the second value.
A control method for controlling an image processing apparatus including an image reading portion, an image recording portion, and a power supply portion for supplying power to the image reading portion and the image recording portion in common, the method comprising the steps of:
- detecting a recording density of image data to be recorded by the image recording portion;
- and
- executing a processing of reducing recording power consumed by the image recording portion when a detection result of the recording density is compared with a predetermined threshold and the detection result of the recording density is equal to or larger than the predetermined threshold;
- wherein the predetermined threshold includes at least a first value and a second value smaller than the first value, and when no image reading is executed by the image reading portion during an image recording operation executed by the image recording portion, the detection result of the recording density is compared with the first value, and
- wherein when image reading is concurrently executed by the image reading portion during the image recording operation executed by the image recording portion, the detection result of the recording density is compared with the second value.
A computer readable medium containing computer-executable instructions for controlling an image processing apparatus including an image reading portion, an image recording portion, and a power supply portion for supplying power to the image reading portion and the image recording portion in common, the computer readable medium comprising:
- computer-executable instructions for detecting a recording density of image data to be recorded by the image recording portion;
- and
- computer-executable instructions for executing a processing of reducing recording power consumed by the image recording portion when a detection result of the recording density is compared with a predetermined threshold and the detection result of the recording density is equal to or larger than the predetermined threshold,
- wherein the predetermined threshold includes at least a first value and a second value smaller than the first value, and when no image reading is executed by the image reading portion during an image recording operation executed by the image recording portion, the detection result of the recording density is compared with the first value, and
- wherein when image reading is concurrently executed by the image reading portion during the image recording operation executed by the image recording portion, the detection result of the recording density is compared with the second value.
