[0002] Currently, projectors, as modern electronic devices, are widely used in various occasions and fields. However, the color of the projection wall or screen often affects the display of the projected image, resulting in abnormal color of the projected image.

[0003] Related technology discloses a projector that obtains the color of the projection wall or screen, and then adjusts the color of the projection image through a built-in image quality algorithm to prevent the color of the projection wall or screen from affecting the normal display of the projection image.

The tones of the main lighting sources in a home vary, and light strips also increase the complexity of the ambient light. Complex ambient light often causes the same projected color to appear different when projected onto the same background wall, resulting in abnormal projected image colors.

[0048] An embodiment of the present disclosure provides a projector, including a light sensor for detecting ambient light illumination and a camera for acquiring background wall color data.

[0049] Combine Figure 1 As shown, an embodiment of the present disclosure provides a method for improving image quality of a projector, comprising:

[0050] S101: The projector determines the ambient light illumination and background wall color data.

[0051] S102 : The projector performs color correction and brightness adjustment on the projection picture data of the projector according to the ambient light illumination and the background wall color data, so that the projection picture data of the projector becomes the final projection picture data.

[0052] The method for improving projector image quality provided by the disclosed embodiments performs intelligent color correction and brightness adjustment on the projected image data based on ambient light illumination and background wall color data, automatically adjusting both brightness and color of the projected image. This allows the projected image to display normally even when the projector's ambient light changes, eliminating the need for manual adjustments to the projected image data. This intelligently improves projection image quality.

[0053] Optionally, the projector performs color correction and brightness adjustment on the projected image data based on the ambient light illumination and background wall color data, including: the projector performs color correction on the projected image data based on the background wall color data and the source image data to obtain intermediate projected image data. The projector performs brightness adjustment on the intermediate projected image data based on the ambient light illumination and projection brightness to obtain final projected image data. The projector adjusts the projected image data to the final projected image data.

[0054] In this way, the projected image data is first color-corrected based on the background wall color data and the source image data. This helps correct the color of the projected image and prevents the color of the projection wall or screen from affecting the normal display of the projected image. Then, based on the ambient light and projection brightness, the intermediate projected image data obtained through color correction is brightness-adjusted to obtain and display the final projected image data. This helps adjust the brightness of the projected image, ensures normal display, and intelligently improves the projection image quality.

[0055] Optionally, the projector performs color correction on the projected screen data of the projector based on the background wall color data and the film source image data to obtain intermediate projected screen data, including: the projector selects the i-th pixel in the projected screen data as the i-th primary pixel to be corrected. The projector performs color correction on the i-th projection RGB value based on the i-th background wall RGB value and the i-th film source RGB value to obtain the i-th intermediate projected RGB value. The i-th background wall RGB value is the RGB value corresponding to the i-th primary pixel to be corrected in the background wall color data, the i-th film source RGB value is the RGB value corresponding to the i-th primary pixel to be corrected in the film source image data, the i-th projection RGB value is the RGB value corresponding to the i-th primary pixel to be corrected in the projector's projected screen data, and the i-th intermediate projected RGB value is the RGB value corresponding to the i-th primary pixel to be corrected in the intermediate projected screen data; i is a natural number, i=1, 2, ..., N; and N is the total number of pixels in the projected screen data.

[0056] In this way, the corresponding projection RGB value is first color corrected according to the background wall RGB value of each pixel and the corresponding source RGB value, which is beneficial to color correct each pixel of the projection image to avoid the color of the projection wall or screen affecting the normal display of the projection image.

[0057] Optionally, the projector performs color correction on the i-th projection RGB value based on the i-th background wall RGB value and the i-th film source RGB value to obtain the i-th intermediate projection RGB value, including: when the first channel value of the i-th film source RGB value is greater than or equal to the first channel value of the i-th background wall RGB value, the projector determines the first channel value of the i-th intermediate projection RGB value to be the difference between the i-th film source RGB value and the first channel value of the i-th background wall RGB value. Alternatively, when the first channel value of the i-th film source RGB value is less than the first channel value of the i-th background wall RGB value, the projector performs inverted color compensation on the first channel value of the i-th film source RGB value to obtain the first channel value of the i-th intermediate projection RGB value.

[0058] Specifically, the first channel value may be an R value, and / or a G value, and / or a B value.

[0059] In this way, at the same pixel location, if the channel value in the source RGB value is higher than or equal to the corresponding channel value in the background wall RGB value, the corresponding channel value of the corresponding intermediate projected RGB value only needs to be set to the difference between the corresponding channel values ​​of the source RGB value and the background wall RGB value. This ensures that the corresponding intermediate projected RGB value will be consistent with the source RGB value when projected onto the wall or screen, regardless of ambient light. This helps prevent the color of the projection wall or screen from affecting the normal display of the projected image.

[0060] Optionally, the projector performs inverse color compensation on the first channel value of the i-th source RGB value to obtain the first channel value of the i-th intermediate projection RGB value, including: the projector determines that the first channel value of the i-th intermediate projection RGB value is the inverse channel value of the first channel value of the i-th source RGB value.

[0061] In this way, at the same pixel location, if a channel value in the source RGB value is lower than the corresponding channel value in the background wall RGB value, the corresponding channel value in the source RGB value is inverted and used as the corresponding channel value in the intermediate projected RGB value. Regardless of ambient light levels, this ensures that the corresponding intermediate projected RGB value will be consistent with the source RGB value when projected onto the wall or screen. This helps prevent the color of the projection wall or screen from affecting the normal display of the projected image.

[0062] Optionally, the projector adjusts the brightness of the intermediate projection screen data based on the ambient light illumination and the projection brightness to obtain the final projection screen data, including: the projector selects the jth pixel in the intermediate projection screen data as the jth final pixel to be corrected. The projector determines the jth final projection RGB value based on the ambient light illumination impact value, the projection brightness impact value, and the jth intermediate projection RGB value. The ambient light illumination impact value is determined based on the change in ambient light illumination; the projection brightness impact value is determined based on the change in projection brightness. The jth final projection RGB value is the RGB value corresponding to the jth final pixel to be corrected in the final projection screen data. j is a natural number, j = 1, 2, ..., N; N is the total number of pixels in the projection screen data.

[0063] In this way, the projected image data is first brightness-adjusted based on the ambient light and projection brightness values ​​to obtain the corresponding final projection RGB values. Color correction of these projection RGB values ​​allows for more accurate color correction of each pixel in the projected image, preventing the color of the projection wall or screen from affecting the normal display of the projected image.

[0064] According to the intermediate projection RGB value of each pixel in the intermediate projection picture data, the ambient light illumination and the projection brightness, the brightness of the intermediate projection RGB value of each pixel is adjusted to obtain the corresponding final projection RGB value. This is conducive to adjusting the brightness of the projection picture after color correction, so that the projection picture displays normally, and is conducive to intelligently improving the projection image quality.

[0065] Optionally, the projector determines the jth final projection RGB value based on the ambient light illumination impact value, the projection brightness impact value and the jth intermediate projection RGB value, including: the projector calculates the product of the ambient light illumination impact value, the projection brightness impact value and the jth intermediate projection RGB value to obtain the jth final projection RGB value.

[0066] In this way, considering the impact of ambient light and projection brightness on the projected image, the final projected RGB value of each pixel is calculated by multiplying the ambient light impact value, the projection brightness impact value, and the intermediate projected RGB value. This facilitates more precise brightness adjustment of the color-corrected projected image, ensuring normal display and intelligently improving projection image quality.

[0067] Optionally, the projector determines the ambient light illumination impact value according to the ambient light illumination change value, including:

[0068]

[0069] Where x is the change in ambient light intensity, and f(x) is the impact value of ambient light intensity.

[0070] Specifically, the value of the ambient light illumination may be [0, 100].

[0071] This helps to better determine the degree of influence of ambient light on the projected image based on the change in ambient light, thereby more accurately adjusting the brightness of the projected image after color correction, so that the projected image displays normally, thereby intelligently improving the projection image quality.

[0072] Optionally, the projector determines the projection brightness impact value according to the change value of the projection brightness, including:

[0073]

[0074] Where y is the change in projection brightness, and f(y) is the impact value of projection brightness.

[0075] Specifically, the value of the projection brightness can be [0, 100].

[0076] This helps to better determine the degree of impact of the projection brightness on the projection image based on the change in projection brightness, thereby more accurately adjusting the brightness of the projection image after color correction, making the projection image display normal, and thus intelligently improving the projection image quality.

[0077] Optionally, after the projector performs color correction and brightness adjustment on the projected image data based on the ambient light illumination and background wall color data so that the projected image data is the final projected image data, the projector further includes: if the ambient light illumination does not change within a set time period, the projector sends a reminder message to the user to save the current image quality scene. Upon receiving the instruction from the user to save the current image quality scene, the projector saves the projected image data to the image quality scene list.

[0078] Specifically, the set duration may be set to 1 minute.

[0079] In this way, after the projector's projection screen is color corrected and the brightness adjusted, if the ambient light illumination tends to be stable and does not change within the set time, a reminder to save the current image quality scene is sent to the user, and the projector's projection screen is saved when instructed to do so by the user, thereby avoiding repeated color correction and repeated brightness adjustment of the projection screen when the ambient light illumination remains unchanged, thereby reducing the energy consumption of the projector.

[0080] Optionally, after the projector performs color correction and brightness adjustment on the projected image data according to the ambient light illumination and the background wall color data so that the projected image data is final projected image data, the method further includes: if the ambient light illumination changes within a set time period, the projector re-determines the ambient light illumination. The projector performs color correction and brightness adjustment on the projected image data according to the re-determined ambient light illumination and the background wall color data so that the projected image data is final projected image data.

[0081] In this way, after color correction and brightness adjustment of the projector's projection image, if the ambient light intensity is unstable and changes within a set period of time, the projector's projection image data will be color corrected and brightness adjusted again based on the ambient light intensity and background wall color data, so that the projected image automatically adjusts in both brightness and color. When the projector's ambient light changes, the projected image can be displayed normally without manual adjustment of the projection image data, which is conducive to intelligently improving projection image quality.

[0082] Optionally, the projector determines the ambient light illumination, including: the projector determines the ambient light illumination when the projector is turned on and / or the ambient light illumination changes within a set time period. The projector determines the background wall color data, including: the projector determines the background wall color data when the projector is turned on.

[0083] In this way, the background wall color data usually does not change, so it can be determined when the projector is turned on, while the ambient light illumination needs to be determined in real time when the projector is turned on and / or when the ambient light illumination changes within a set time period, which is conducive to timely color correction and brightness adjustment of the projector's projection picture data.

[0087] S203: When the ambient light illumination does not change within a set time period, the projector sends a reminder message to the user to save the current image quality scene.

[0088] S204 : When the projector receives the instruction to save the current image quality scene from the user, the projector saves the projected image data to the image quality scene list.

[0089] The method for improving the image quality of a projector provided by the embodiment of the present disclosure is adopted to perform intelligent color correction and brightness adjustment on the projected image data of the projector according to the ambient light illumination and background wall color data, so that the projected image is automatically adjusted in two dimensions: brightness and color. When the ambient light of the projector changes, the projected image can be displayed normally without manually adjusting the projected image data, which is conducive to intelligently improving the projection image quality. After the color correction and brightness adjustment of the projected image of the projector are performed, if the ambient light illumination tends to be stable and does not change within the set time period, a reminder to save the current image quality scene is sent to the user, and the projected image of the projector is saved when instructed to do so by the user, so as to avoid repeated color correction and repeated brightness adjustment of the projected image when the ambient light illumination remains unchanged, thereby reducing the energy consumption of the projector.

When the ambient light of the projector changes, the projection screen data can be displayed normally without manually adjusting the projection screen data, which is beneficial to the intelligent improvement of the projection image quality. After the projection screen of the projector is color corrected and the brightness is adjusted, if the ambient light illumination is unstable and changes within the set time, the projection screen data of the projector is color corrected and the brightness is adjusted again according to the ambient light illumination and the background wall color data, so that the projection screen is automatically adjusted in two dimensions: brightness and color. When the ambient light of the projector changes, the projection screen data can be displayed normally without manually adjusting the projection screen data, which is beneficial to the intelligent improvement of the projection image quality.

[0100] S404: The projector adjusts the projection image data of the projector to final projection image data.

[0101] The method for improving projector image quality provided by the disclosed embodiments first performs color correction on the projected image data based on background wall color data and source image data. This facilitates color correction of the projected image to prevent the color of the projection wall or screen from affecting the normal display of the projected image. The intermediate projected image data obtained through color correction is then brightness-adjusted based on ambient light and projection brightness to obtain and display the final projected image data. This facilitates brightness adjustment of the projected image, ensuring normal display and intelligently improving projection image quality.
