Currently competition in terms of resolution and contrast of photos from digital cameras are widely mentioned. The higher resolution the photos contain; the more details the picture has. This fact enables the more details of pictures which also hold much more capacity of data. This also causes the electronic devices to be updated all the time to cope with those problems. Therefore the conventional devices are obsolete. This research has been developed and applied to improve digital photos with high contrast. The researcher has solved the problems by keeping the average error of the lowest results and improving heat histogram of various curves. The heat will break the histogram of the original image into n part by the concave side of the heat histogram. The part of this histogram is equal to n+1 and then smooth each other heap histogram independently. The result showed that the Tennengrade or contrast of the image is higher than the original one. However it can retain brightness errors (AMBE) as well

The purposes of this research were : 1) to study the formulation of eggshell clay suitable for development which is a new material in home decoration products inspired by stucco work Wat Phra Chetuphon Wimol Mangkhalaram2) to design and fabricate home decoration products from inspiring stucco work Wat Phra Chetuphon Wimol Mangkhalaram with eggshell clay and 3) to study the satisfaction of experts on home decoration products from the inspiration of the stucco work Wat Phra Chetuphon Wimol Mangkhalaram with eggshell clay. The processes of the research were to study the formulation of clay from eggshell by assigning 5 experts 3 clay mold experts and 2 clay sculptors and select the most suitable formula for 1 formula design and development of home decoration products inspired by stucco work Wat Phra Chetuphon Wimol Mangkhalaram 3 types: mirror frame lamp and vase 3 types of each type 3 types of design 5 experts 2 design instructors 3 interior designers 3 types of the most suitable type 2 interior designers selected the most suitable type for each type of 3 ones. Then fabricated products for home decoration eggshell molding from inspiration stucco work Wat Phra Chetuphon Wimol Mangkhalaram.There were 10 experts for product evaluation ; 5 of them were from clay expertises and the remaining persons were the product designs and inquire about the satisfaction of experts with the product. The results showed that: 1) experts give the highest level of satisfaction to an appropriate eggshell formulation equal to 4.25 in all areas in formula 1 2) research results for product designs experts are interested in choosing a home decoration product designs from the inspiration of the stucco work of Wat Phra Chetuphon Wimol Mangkhalaram with eggshell clay. Classifying products for mirror frame type 2 (3 people 60 %) lamp type 2 ( 4 people 80%) and vase type 1 (3 people 60%) and 3) experts have overall satisfaction towards home decoration products from the inspiration of the stucco work of Wat Phra Chetuphon Wimol Mangkhalaram with eggshell clay at the highest score In every aspect of satisfaction such as product functional material and satisfaction with an overall average score of 4.53 from 10 experts.

This research has objectives to study about production process of four types of processed food product to study quality of processed food product supplemented with cassava to study about consumer test towards processed food product to study quality of processed food product supplemented with cassava to study about consumer test towards processed food product made supplemented with cassava. From the test it was found about the appropriate quantity of cassava to supplement into four types of processed food product. The researcher had consumer test in order to test about acceptance of testers who are 40 instructors in field of Food and Nutrition field of Food and Nutrition Science and field of Food Service Industry using method of giving marks for favor in type of 9-point hedonic scale. The researcher supplemented cassava into barbecue powder French Fries at level of 0 2 4 and 8 percent of all ingredient. It was found that testers accepted the French Fries at level of 2 percent to be in level of moderate favor. The researcher made nuggets supplemented with cassava at level of 0 50 75 and 100 percent of all in gradient. It was found that testers accepted the nuggets at level of 75 percent. The researcher supplemented cassava into fish cake at level of 0 40 60 and 80 percent of all ingredient. It was found that testers accepted the fish cake supplemented with cassava at level of 60 percent to be in level of moderate favor. The researcher made crispy cassava mixed with Barbecue power at level of 2 4 6 and 8 percent of all ingredient. It was found that the testers accepted the crispy cassava at level of 4 percent to be in level of moderate favor. Regarding nutritional value of French Fries it was found that cassava for 2 percent in French Fries with Barbecue powder had moisture value for 28. 25 percent fat value for 27.21 percent fiber for 2.22 percent ash for 2.28 percent and protein for 2.22 percent. Nugget it was found that nugget supplemented with cassava for 75 percent had moisture value for 53.35 percent fat value for 6.47 percent fiber for 1.67 percent ash for 1.94 percent and protein for 17.98 percent. Fish cake it was found that fish cake supplemented with cassava for 60 percent the chemical quality had moisture value for 50.92 percent fat value for 13.78 percent fiber for 2.69 percent ash for 2.85 percent and protein for 21.97 percent. Crispy cassava mixed with Barbecue powder it was found that crispy cassava mixed with Barbecue powder for 4 percent chemical quality had moisture value for 1.39 percent fat value for 21.04 percent fiber for 3.64 percent ash for 3.05 percent and protein for 2.22 percent. However supplementing of cassava in four types of processed food products can be made but there shall be realizing about chemical elements of primary components such as moisture and fat quantity. These elements may affect the physical features for example smell and taste and texture. These features had effect on product acceptance.
