Abstract

A projection device including a projecting unit, an input unit and a processor and an image adjusting method of the projection device are provided. The projecting unit projects a first image to a projection surface. The input unit receives an input operation. The processor is electrically connected to the projecting unit and the input unit. The processor divides the first image into at least one block according to the input operation, selects one block from the at least one block to serve as a to-be-adjusted block, defines at least one control point within the to-be-adjusted block, and adjusts a position of the at least one control point so as to adjust a part of the first image. With the device and method provided, a user may independently adjust one block of the image without adjusting other blocks, so as to improve image authenticity and user satisfaction.

Claims22

Dependent claims

A projection device, comprising:

a projecting unit, projecting a first image to a projection surface;
an input unit, receiving an input operation;
a processor, electrically connected to the projecting unit and the input unit, wherein the projecting unit, the input unit and the processor are respectively configured to perform the following operations:
the processor selecting a block-number option from a first group according to the input operation received by the input unit, wherein the first group includes a plurality of block-number options, such that the first image is divided into at least one block;
the processor selecting one block from the at least one block according to the input operation received by the input unit, wherein the block serves as a to-be-adjusted block and the other blocks of the at least one block serve as not-adjusting blocks,
for the to-be-adjusted block, the processor selecting a control-point-number option from a second group according to the input operation received by the input unit, wherein the second group includes a plurality of control-point-number options, so as to define at least one control point within the to-be-adjusted block,
the processor adjusting a position of the at least one control point so as to adjust a part of the first image.
