Electronic device and control method therefor
An electronic device according to various embodiments of the present invention may comprise: a display; a processor for generating a frame image; and a display driving circuit for driving the display, the display driving circuit including an image processing module and a memory, wherein the display driving circuit is configured to acquire the frame image from the processor, generate a different frame image by applying a designated effect to at least a partial area of the frame image, and display the different frame image through the display.
1. An electronic device, comprising:
a display;
a display driver integrated circuit (IC) configured to drive the display; and
a processor configured to generate a frame image and provide the fame image to the display driver IC,
wherein the display driver IC is configured to:
obtain the frame image from the processor,
divide the frame image corresponding to a screen of the display into a plurality of regions vertically or horizontally, and
apply a privacy effect to the plurality of regions, and
wherein two adjacent regions of the plurality of regions to which the privacy effect is applied include different effect value each other.
2. The electronic device of claim 1 , wherein the display driver IC is configured to obtain, from the processor, at least partial control information of control information related to the frame image and control at least part of generating or displaying the frame image which the privacy effect is applied based on the at least partial control information.
3. The electronic device of claim 1 , further comprising another processor, wherein the display driver IC is configured to obtain, from the other processor, at least partial control information of control information related to the frame image and control at least part of generating or displaying the frame image to which the privacy effect is applied based on the at least partial control information.
4. The electronic device of claim 3 , further comprising at least one sensor, wherein the other processor forms at least part of a processor configured to control the at least one sensor.
5. The electronic device of claim 1 , wherein the display driver IC is configured to generate the frame image to which the privacy effect is applied when a first specified application is run on the electronic device and abstain from generating the frame image to which the privacy effect is applied when a second specified application is run on the electronic device.
6. The electronic device of claim 1 , wherein the display driver IC is configured to generate the frame image to which the privacy effect is applied when content included in the frame image is first specified content and abstain from generating the frame image to which the privacy effect is applied when the content included in the frame image is second specified content.
7. The electronic device of claim 1 , wherein the display driver IC is configured to generate the frame image to which the privacy effect is applied when a user input meets a specified condition and abstain from generating the frame image to which the privacy effect is applied when the user input does not meet the specified condition.
8. The electronic device of claim 7 , wherein the display driver IC is configured to vary a kind, strength, magnitude, or pattern of the specified effect when the user input meets a specified value.
9. The electronic device of claim 1 , wherein the display driver IC is configured to change the at least a portion of the frame image into a specified color using a Gaussian function.
10. The electronic device of claim 1 , wherein the display driver IC is configured to apply a gradation effect to the at least a portion of the frame image.
11. A method for controlling an electronic device, the method comprising:
obtaining, by a display driver integrated circuit (IC) of the electronic device, a frame image from a processor of the electronic device;
dividing, by the display driver IC, the frame image corresponding to a screen of a display of the electronic device into a plurality of regions vertically or horizontally; and
applying, by the display driver IC, a privacy effect to the plurality of regions,
wherein two adjacent regions of the plurality of regions to which the privacy effect is applied include different effect value each other.
12. The method of claim 11 , wherein the applying of the privacy effect includes obtaining at least partial control information of control information related to the frame image from an application processor that generates the frame image and controlling at least part of generating or displaying the frame image to which the privacy effect is applied based on the at least partial control information.
13. The method of claim 11 , wherein the applying of the privacy effect includes obtaining at least partial control information of control information related to the frame image from a processor different from an application processor that generates the frame image and controlling at least part of generating or displaying the frame image to which the privacy effect is applied based on the at least partial control information.
14. The method of claim 13 , wherein the applying of the privacy effect includes generating the other frame image when a first specified application is run and abstaining from generating the frame image to which the privacy effect is applied when a second specified application is run.
15. The method of claim 11 , wherein the applying of the privacy effect includes generating the other frame image when content included in the frame image is first specified content and abstaining from generating the frame image to which the privacy effect is applied when the content included in the frame image is second specified content.
