Abstract
A display control apparatus and method is disclosed wherein the amount of use of a memory to be used to store an image to be displayed can be reduced. The display control apparatus has an execution section, a first retaining section, an image processing section, a second retaining section and reflect section. The image processing section and the first and second retaining sections being controlled with an application program interface provided by the middleware and called by the application program. In addition, a display control method for a display control apparatus which causes an image corresponding to image data to be displayed on a display unit, including a first retaining step, an image processing step, and a reflection step.
Claims9
A display control apparatus for causing an image corresponding to image data to be displayed on a display unit, comprising:
- an execution section configured to execute an application program and middleware for controlling action of said display control apparatus;
- a first retaining section configured to retain inputted image data having a first width and height;
- a second retaining section configured to retain image data having a second width and height different from the first width and height;
- an image processing section configured to perform an expansion process or a reduction process for image data read out from the first retaining section having the first width and height, the resulting image data having the second width and height and being stored to the second retaining section;
- and
- a reflection section configured to reflect the image data retained in said second retaining section on a display of the display unit;
- said image processing section and said first and second retaining sections being controlled with an application program interface provided by the middleware and called by the application program.
A display control method for a display control apparatus which causes an image corresponding to image data to be displayed on a display unit, comprising the steps of:
- receiving and retaining, by the display control apparatus, inputted image data in a first retaining section configured to retain inputted image data having a first width and height;
- reading out the image data retained by the first retaining section and performing an image process including an expansion process or a reduction process for the image data;
- secondly retaining image data of a result of the image process by the process at the image processing step in a second retaining section configured to retain image data outputted by the image process having a second width and height different from the first width and height;
- and
- reflecting the image data retained by the second retaining section on a display unit of the display apparatus;
- the image processing step and the first and second retaining sections being controlled with an application program interface provided by middleware and called by an application program.
