As shown in fig. 1, an embodiment of the present invention provides a method for managing power of a multi-partition platform, where the method may include the following steps:
step S101: acquiring first power of a power supply of a multi-partition platform and second power born by a light source, and determining the maximum brightness partition number which can be covered by the light source based on the first power and the second power; and re-determining the minimum partition number reaching the maximum brightness value according to the maximum brightness value corresponding to the maximum brightness partition number.
Specifically, the multi-partition platform may be a local dimming (local dimming) -based multi-partition platform, and may be integrated in a television, a computer, or a like; further, the maximum power of the power supply (i.e. the first power) of the multi-partition platform, and the maximum power that the light source can bear are obtained, for example: the maximum power of the power supply is P _ max, the maximum power which can be borne by each light source of the multi-partition platform is P _ imax, N is obtained through N = P _ max/P _ imax, and N is the maximum brightness partition number and represents the partition number which can be lightened under the condition that the brightness of the light source is determined to reach the maximum value; that is, the maximum number of luminance bins that can be covered by the light source is determined based on the first power and the second power.
Further, according to the maximum brightness value corresponding to the maximum brightness partition number, re-determining the minimum partition number reaching the maximum brightness value; since there is a superposition factor in the light source, it is preferable to further calculate the minimum number of divisions N at which the same luminance value is reached based on the maximum number of luminance divisions N. After determining N, measuring and acquiring the maximum brightness corresponding to the maximum brightness partition number N, and further, executing in a loop: acquiring N-1, N-2, \8230Onbrightness (namely measuring a first brightness value of a first partition), and taking N as the minimum partition number according to the acquired brightness which can reach the same brightness; namely, the method for determining the minimum partition number n is to re-determine the minimum partition number reaching the maximum brightness value according to the maximum brightness value corresponding to the maximum brightness partition number, and includes: taking the area corresponding to the maximum brightness partition number as a first partition, and circularly executing N1-N2: n1: measuring a first brightness value of a first partition, and judging whether the first brightness value is smaller than a maximum brightness value; if the number of the partitions corresponding to the first partition is determined as the minimum number of the partitions, ending the circulation; otherwise, executing the step N2; n2: and reducing the number of the partitions corresponding to the first partition, taking the reduced partitions as the first partition, and executing N1. The minimum number of partitions is determined by looping.
Step S102: and respectively comparing the minimum partition number with the partition numbers corresponding to the maximum brightness windows of the various signals, and determining the partition power corresponding to the maximum brightness windows of the various signals according to the comparison result.
Specifically, after the minimum partition number is determined, the unit power of each partition is determined, and then the partition power of the maximum brightness window of the multiple signals corresponding to the maximum window of the multi-partition platform is determined. The signal maximum brightness window may be a white window, and various signal maximum brightness windows may be set based on the percentage of the white window in the maximum window, for example, as shown in fig. 2: the maximum brightness window of signal occupies 10% of the maximum window and is a maximum brightness window of signal, the maximum brightness window of signal occupies 20% of the maximum window and is another maximum brightness window of signal, and so on, until 100% (i.e. maximum window). Preferably, when determining the maximum brightness windows of the various signals, the maximum brightness window of the signals is set to be a white window, and the other parts of the maximum window except the white window are black. It is understood that in fig. 2, the name "maximum white window" represents the maximum luminance window of each signal, and the percentage values 10%, 20%, \ 8230, 100% correspondingly represent the maximum luminance window of a signal.
Specifically, in an embodiment of the present invention, the method for determining the unit power of each partition, and then determining the partition power of the different signal maximum luminance windows, includes:
1) When the set number of segments to be lit is smaller than the minimum number of segments n that can be lit at the time of the maximum lighting, the unit power of each segment is arranged at the maximum power (i.e., the second power) P _ imax of the light source, and the segment power P corresponding to the set number of segments can be obtained by P = P _ imax n.
2) The set number of segments that need to be lit is greater than the minimum number of segments n that can be lit at the time of the maximum lighting, and the unit power Pi _ max = P _ max/segment number m (which can be determined from the number of lit light sources) for each segment, where P _ max is the first power of the power supply.
3) The unit power Pi _ max of the partition corresponding to the maximum luminance window of each signal corresponding to 10%, 20%. 100% of the entire window can be determined according to the method of 1) or 2), respectively; that is, the comparing the minimum partition number with the partition numbers corresponding to the maximum brightness windows of the various signals, and determining the partition powers corresponding to the maximum brightness windows of the various signals according to the comparison result includes: for each kind of signal maximum brightness window, performing: under the condition that the number of partitions of the signal maximum brightness window is smaller than the minimum number of partitions, taking the second power born by the light source as unit power, and determining the partition power of the signal maximum brightness window by using the number of partitions and the unit power; and when the number of partitions of the signal maximum brightness window is larger than the minimum number of partitions, calculating unit power corresponding to the signal maximum brightness window based on the first power and the number of partitions of a power supply, and determining the partition power corresponding to the signal maximum brightness window by using the number of partitions and the unit power.
Further, for each signal maximum brightness window, performing: determining a first corresponding relation among the number of partitions corresponding to the maximum brightness window of the signal, the partition power corresponding to the number of partitions and the average brightness value corresponding to the number of partitions; and storing the first corresponding relation.
Fig. 2A shows, for example, 1000 partitions, the corresponding relationship among the number of partitions of the maximum luminance window of the signal, luminance (for example, average luminance value), actual output power, unit power (power of each partition), and data included in each first corresponding relationship determined based on the embodiment of the present invention, as shown in fig. 2A, the first corresponding relationship, for example, the number of partitions of the maximum luminance window of the signal corresponding to 20%, includes an average luminance value of 729.7, an actual output power of 85, and a unit power of 0.425 (the partition power can be calculated by the unit power and the number of partitions); the average brightness value corresponding to each set partition number may be obtained by SoC (where SoC is a system-on-chip that has an integrated circuit with a dedicated target), and for example, the SoC may obtain the average brightness value by histogram statistical data of the screen brightness. It is understood that the data in fig. 2A is only an example, the number of partitions of the maximum brightness window of the signal, the brightness (e.g., average brightness value), the actual output power, and the unit power (power of each partition) are different for different devices and different partition numbers, and the specific values and formats are not limited by the present invention. Further, each first correspondence is stored to a data source (e.g., a data table, a file, etc.).
Step S103: determining one or more partitions of a picture to be output, selecting a target signal maximum brightness window matched with the partition number of the partitions from the multiple signal maximum brightness windows, and taking the partition power of the target signal maximum brightness window as the partition power corresponding to the partitions; and outputting the picture to be output based on the average brightness value of each partition and the partition power corresponding to the partition.
Specifically, after the first correspondence relationship shown in fig. 2A is determined, when the picture is output, one or more partitions of the picture may be determined, and in the case of multiple partitions, for each partition, a target signal maximum luminance window matching the number of partitions of the partition is selected from the multiple signal maximum luminance windows by using the first correspondence relationship, for example, if the number of partitions matches 50% of the number of partitions of the signal maximum luminance window, 50% of the corresponding signal maximum luminance window is the target signal maximum luminance window, and further, the partition power of the 50% of the corresponding signal maximum luminance window is used as the partition power for the partition of the output picture.
The average brightness of the output picture of each frame of the normal picture can be obtained by SoC, after obtaining, matching mapping is performed with the table of each first corresponding relationship shown in fig. 2A, and in which range, according to the matching result, the closest Pi _ max (unit power) value is set, and regardless of the gray value of each partition under the frame, each partition under the frame is assigned with this value, and since the unit power is assigned with the maximum power, the actual final power can be output after local dimming processing, that is, further, for each signal maximum brightness window, the following steps are performed: the partition power corresponding to the signal maximum brightness window is the configured maximum power, adjustment is carried out based on the maximum power, and the power corresponding to the adjustment result is used as the actual output power corresponding to the partition number; and adding the actual output power corresponding to the partition number to the first corresponding relation corresponding to the signal maximum brightness window. As shown in fig. 2A. It will be appreciated that since the maximum Pi _ max of the partition selected after the average luminance is matched, the actual output power is within the range of the table of the first correspondence, and does not exceed the maximum power of the power supply. And, the actual output power (or the total actual output power) corresponding to the adjustment result may be the same as the configured maximum power. Because the power is adjusted to the actual output power through the local dimming, the efficiency of determining the partition power is further improved, and the complexity of determining the partition efficiency is reduced.
Further, as shown in fig. 2A, preferably, the setting the first corresponding relationship of the number of partitions further includes: setting an average gray value corresponding to the number of the partitions; wherein the average gray value and the actual output power have a positive correlation proportional relationship; outputting a picture by using the multi-partition platform according to the partition power corresponding to each set partition number and the corresponding average brightness value, wherein the method comprises the following steps of: acquiring an average gray value of a picture to be output, determining partition power corresponding to the average gray value according to the first corresponding relation, and outputting the picture by using the multi-partition platform according to the partition power corresponding to each set partition number and the corresponding average brightness value. In the embodiment of the present invention, fig. 2B shows that the average gray-scale value and the actual output power included in the embodiment of the present invention have a positive correlation proportional relationship. I.e. the average grey value of the picture can be used to map the maximum power per frame.
Further, there are two methods for outputting the to-be-output picture:
the first method comprises the following steps: acquiring the average gray value of each partition of the picture to be output, determining the partition power corresponding to the average gray value of each partition according to the first corresponding relation, and outputting the picture to be output according to the partition power of each partition and the corresponding average gray value.
The second method comprises the following steps: outputting the to-be-output picture based on the brightness value of each partition of the multi-partition platform and the partition power corresponding to the partition, including: acquiring a first average brightness value of the picture to be output; searching for a first partition power matching the first average brightness value from a plurality of the first corresponding relations; and outputting the picture to be output based on the first partition power.
It follows that embodiments of the present invention exploit the peak brightness improvement that algorithm optimization can achieve without increasing hardware cost.
