Detailed Description
The scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that the detailed description and the specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only.
Fig. 1 shows a flowchart of a picture display control method according to an embodiment of the present invention, which starts with step S10 of checking whether there is picture data conforming to a predetermined thumbnail policy according to resolution and performance factors of a current terminal in response to receiving a data request. The performance factor is determined from at least two of the following parameters of the terminal: hard disk rotation speed, memory size, GPU frequency and display bit width, display resolution, and CPU frequency and core number. Specifically, the performance factor is equal to the sum of at least two of the following:
generally, the hard disk weight is more than or equal to the memory weight, the GPU weight is more than or equal to the display weight, and the CPU weight is more than or equal to the display weight. The sum of all the adopted weights is 1, and the specific weights can be adjusted according to the influence factors of the actual terminal so as to meet the optimal calculation. The respective reference values may be determined according to parameters of terminals that are medium or more at the time. For example, at the current stage, it may be determined that the reference hard disk rotation speed is 7200, the reference memory size is 2G, the reference GPU frequency shows the bit width is 672 × 128, the reference resolution is 720 × 1280, and the reference CPU frequency × core number is 2 × 1.2. For example, in the case of a terminal having a GPU, the performance factor of the terminal may be determined as (disk speed/7200) × 0.3+ (memory/2G) × 0.3+ ((GPU frequency) × display bit width)/(672 × 128)) × 0.2+ ((width of resolution) × high)/(720 × 1280)) × 0.1+ ((CPU frequency × core number)/2 × 1.2)) + 0.1. In the absence of the GPU, the performance factor of the terminal may be determined as (disk speed/7200) × 0.3+ (memory/2G) × 0.3+ ((width × height of target resolution)/720 × 1280)) × 0.2+ ((CPU frequency × core number)/2 × 1.2)) × 0.2. If the calculated performance factor >1, the value of the performance factor is taken to be 1. In an embodiment, the predetermined thumbnail policy includes: for pictures larger than the terminal resolution multiplied by the performance factor, generating a preview thumbnail with a default size and generating display pictures with the same target resolution, wherein the target resolution is equal to the terminal resolution multiplied by the performance factor, and the default size of the preview thumbnail is 250 × 250 or 320 × 320; for the picture of the thumbnail which is smaller than the target resolution and larger than the default size and multiplied by the performance factor, only the preview thumbnail is generated, the display picture is not generated, and the original picture can be directly used for display; the original image is directly displayed without any processing for the picture of the preview thumbnail smaller than the default size. When there is picture data that conforms to the predetermined thumbnail policy, the process proceeds to step S20, and a data preparation completion signal is sent to ensure that the picture data can be loaded. When there is no picture data complying with the predetermined thumbnail policy, the process proceeds to step S15, and the corresponding picture is processed according to the predetermined thumbnail policy, generating picture data complying with the predetermined thumbnail policy. After step S15, the process proceeds to step S20. In response to receiving the data preparation completion signal, the picture data conforming to the predetermined thumbnail policy is acquired and loaded into the memory, and a data loading completion notification is sent to ensure that the display data can be updated at step S30. In step S40, in response to receiving the data load completion notification, the picture display content is changed based on the picture data complying with the predetermined thumbnail policy. Therefore, the picture loading matched with the terminal picture loading capacity can be realized, and the loading speed is increased. Meanwhile, when the original image is far larger than the resolution of the current terminal, the image corresponding to the resolution of the current terminal can be generated and loaded, so that the loading speed is increased, and the display effect is not influenced.
Fig. 2 shows a flowchart of a picture display control method according to another embodiment of the present invention, which includes step S50, in addition to including all the steps shown in fig. 1, of requesting again a higher resolution picture and waiting for a process notification to allow the user to see a larger, better-effect picture when the size is larger than the thumbnail display effect when the picture display size is dynamically changed.
Fig. 3 shows a schematic diagram of a picture display control system according to an embodiment of the invention, the system comprising: the picture data checking module 10 is used for responding to the received data request, and checking whether picture data which accord with a preset thumbnail strategy exist according to the resolution and the performance factor of the current terminal; the picture data generating module 20 is configured to, in response to that the picture data does not exist, process a corresponding picture according to the predetermined thumbnail policy to generate the picture data; a data preparation completion signal transmitting module 30 for transmitting a data preparation completion signal in response to the presence or ready of the picture data; a data loading module 40, configured to, in response to receiving the data preparation completion signal, acquire the picture data and load the picture data into a memory, and send a data loading completion notification; a picture display change module 50, configured to, in response to receiving the data loading completion notification, change picture display content based on the picture data; and a re-request picture module 60 for re-requesting a picture of a higher resolution and waiting for a processing notification when the size of the picture display is larger than a default thumbnail display effect in response to dynamically changing the size of the picture display.
