1. A subtitle control method, applicable to a display apparatus, for dynamically adjusting a subtitle of an original image, the original image comprising a right-eye frame and a left-eye frame, the right-eye frame comprising right-eye subtitle information, the left-eye frame comprising left-eye subtitle information, the method comprising:
selecting an adjusted subtitle display mode;
determining a shift distance of the right-eye subtitle information and the left-eye subtitle information;
selectively adjusting the shift distance according to the adjusted subtitle display mode and a selected 3D depth, such that an adjusted subtitle presented by the right-eye frame and the left-eye frame shows an adjusted subtitle 3D depth; and
determining an original subtitle display mode, comprising:
comparing the shift distance of the right-eye subtitle information and the left-eye subtitle information;
determining the original subtitle display mode as a static display mode when the shift distance is substantially stable; and
determining the original subtitle display mode as a dynamic 3D display mode when the shift distance changes with time;
wherein, the adjusted subtitle display mode comprises a static display mode and a dynamic 3D display mode, and when the adjusted subtitle display mode is different from the original subtitle display mode, the selected 3D depth is generated according to the adjusted subtitle display mode to accordingly adjust the shift distance.
2. The method according to claim 1, wherein when the adjusted subtitle display mode is the dynamic 3D display mode, and the selected 3D depth is associated with a 3D depth of an object in the original image.
3. The method according to claim 1, wherein when the adjusted subtitle display mode is different from the original subtitle display mode, the selected 3D depth is provided by a user to accordingly adjust the shift distance.
4. A subtitle control device, applicable to a display apparatus, configured to dynamically adjust a subtitle of an original image, the original image comprising a right-eye frame and a left-eye frame, the right-eye frame comprising right-eye subtitle information, the left-eye frame comprising left-eye subtitle information, the device comprising:
a subtitle capturing unit, configured to capture the left-eye subtitle information from the left-eye frame and the right-eye subtitle information from the right-eye frame, and determining an original subtitle display mode according to a shift distance of the right-eye subtitle information and the left-eye subtitle information;
a frame processing unit, configured to generate a 3D depth; and
a subtitle superimposing unit, configured to selectively generate an adjusted left-eye frame and an adjusted right-eye frame according to the 3D depth;
wherein, an adjusted subtitle presented by the adjusted right-eye frame and the adjusted left-eye frame shows an adjusted subtitle 3D depth;
wherein when it is determined to change the original subtitle display mode, the subtitle superimposing unit adjusts the shift distance according to the 3D depth; and
wherein when the adjusted subtitle display mode is the dynamic 3D display mode, the frame processing unit generates the 3D depth according to a 3D depth of an object in the original image.
5. The device according to claim 4, wherein the subtitle capturing unit determines the original subtitle display mode as a static display mode when the shift distance is substantially stable, and determines the original subtitle display mode as a dynamic 3D display mode when the shift distance changes with time.
6. The device according to claim 4, wherein when it is determined to change the original subtitle display mode, the 3D depth is provided by a user for the subtitle superimposing unit to accordingly adjust the shift distance.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A refrigerant cycle comprising:
at least two compressors, each of said compressors receiving a suction line for delivering refrigerant to be compressed, said suction line receiving refrigerant from a common suction manifold, and each of said compressors having a discharge line for delivering a compressed refrigerant to a downstream discharge common manifold;
a first heat exchanger downstream of said discharge manifold, and an economizer heat exchanger downstream of said first heat exchanger, a refrigerant tap tapping a refrigerant line communicating said first heat exchanger to said economizer heat exchanger, and an expansion device on said tap line, upstream of said economizer heat exchanger, an economizer manifold returning said tapped refrigerant downstream of said economizer heat exchanger to each of said compressors, and an economizer return line communicating said economizer manifold to an intermediate compression point in each of said compressors.
2. A refrigerant cycle as set forth in claim 1, wherein an economizer valve controls flow of returned economizer refrigerant to at least one of said compressors.
3. A refrigerant cycle as set forth in claim 2, wherein a first economizer shutoff valve is placed upon one of said economizer return lines, with a second economizer shutoff valve being placed on said economizer manifold.
4. A refrigerant cycle as set forth in claim 1, wherein an unloader line connects said economizer return line back to a line leading into a suction side of said compressor, with an unloader valve controlling flow through said unloader line.
5. A refrigerant cycle as set forth in claim 4, wherein said unloader line communicates with a pressure equalization line communicating each of said compressor suction sides to equalize pressure on each of said compressor suction sides.
6. A refrigerant cycle as set forth in claim 1, wherein an unloader line communicates said economizer return lines to a flow line communicating with a suction side of each of said compressors.
7. A refrigerant cycle as set forth in claim 6, wherein said unloader line communicates with a pressure equalization line communicating each of said compressor suction sides to equalize pressure on each of said compressor suction sides.
8. A refrigerant cycle as set forth in claim 6, wherein a single unloader valve is placed on an unloader manifold communicating with each of said economizer return lines through separate unloader lines, and said single unloader valve controlling flow from each of said unloader lines to a line returning refrigerant to a suction chamber of said compressors.
9. A refrigerant cycle as set forth in claim 8, wherein a pressure equalization line separately communicates the compressor shells of each of said compressors, and said unloader valve returning refrigerant from said economizer return line to said pressure equalization line when said unloader valve is open.
